Sick toadstool coral - parasite? Hi Crew, <Hey Matt> My
toadstool coral appears sick. Please see attached pic. He closed up
last week, and hasn't come back out since. <Not unlike a
toadstool to do this, but.....> There are what appears to be bite
marks on its flesh. <Possible stinging, poisoning, or is a
clownfish taking up residence in it> There is a Clarkii clown in the
tank that has began living in the coral the last few months as though
it were an anemone. <I see> Is it possible that he is responsible
for the damage? <Yes. Clownfish do bite to stimulate the anemone at
times. Check out our forums and ask around in there for more specific
information. Keep an eye on the toadstool however, as it has been noted
there are some mollusks that burrow into the crown or stalk of this
coral and feed from the inside out. May look unsightly, but keep your
water quality up and clean out the wound with a syringe or turkey
baster and I feel the coral will make a full recovery. Sarcophyton
corals are extremely hardy and resilient.> Or is there some other
forces at work? <Possible. These corals are also known for closing
shop for a few couple of weeks and shedding floc (chemical build-up,
digested foodstuffs, etc.) during growth periods. Keep an eye on it and
send us an update. Keep a journal if possible. You know, something to
reference at a later time just in case you see something like this
again. I just thought of something......... I remember Sally Joe over
at Graford working to connect clownfish to Sarcophyton corals. Do some
research on their site before calling them as they are with limited
abilities, trying to save money. (Aren't we all) If you can't
find anything specific to your situation then give Lionel a call. I am
sure he can relate some stuff he has seen or has heard discussed around
the shop. www.garf.org -Paul> Everything else in the tank is doing
great. <Glad to hear> Cheers, Matt Another Toadstool question - 11/10/03 I have a common toadstool coral. The stalk is about 5" tall and 1" in diameter. About 10 days ago, while I was cleaning the glass, the magnet came loose and hit the stalk of the toadstool. <Ouch> Since that time, it has what appears as a "bruise" on its stalk which seems to be getting larger. <Keep an eye on it. Don't panic and don't move the coral> The coral is bent over at the bruise point and doesn't seem able to stand upright. <just wait> For the first week after the accident, the polyps were closed and I didn't think it was going to survive. <A very hardy coral. Maintain water quality or maybe even increase water changes. Leave the coral be for a while.> Now, it's polyps have opened, but he is still bent in half. <Give it time> Is there anything I can do for it? <Leave it be. It may recover to an upright position and it may not. Either way it will likely survive the ordeal. You should see the "abuse" my several Sarcophytons have to endure (meaning cuttings for propagation) - Paul> Thanks Collapsing Coral And Rising Nitrate Hi, <Hi there! Scott F. here today> I talked to ya'll last week. I now have finger leather that looks like its insides have been sucked out of it. It is just lying there almost flat and is a brownish color. It had been looking so good. <It might be history...Not to be too premature here, but it may be beyond salvaging at this point. You could potentially try cutting out any salvageable parts of the colony and placing them in on rubble to re-attach... The reason for this collapse is not entirely understood. Eric Borneman, in his book "Aquarium Corals", suggests that salinity variations, physical trauma, or injury may play roles in this condition> Now I never did find that thing that was on my mushroom leather that you thought might be some kind of Nudibranch. <Hmm...the "thing" might have been the source of the "trauma"?> Also there is something on my rock that I have just noticed in the last few days. It is shaped kinda like a mushroom, they are really small, the stalk is so small I can hardly see it and the round top is a lot smaller that a dime maybe the size of the tip of a small persons finger. I can't tell the color of the stalk very well but it appears to be kinda a brownish color, the round top has little things standing up all around its edge and these and the top is clear. If my shrimp or fish get close to them they suck themselves back into the rock and you can't see the at all, you wouldn't even know there had been something there. <Hmm, I'd love to see a photo and I could attempt an ID on this animal> I did another 10% water change and vacuumed Sunday, my nitrate is still high around 60 I can't seem to get it to go down and stay everything else seem to be ok. <Well, consistent water changes over time, combined with solid husbandry techniques (skimming, use of chemical filtration media, etc.) over time will do the trick. Initial, larger changes can help get things started> I really need some help and I hope you guys can tell me what to do. Like I have told you I am just starting and I love my little ocean friends and want to really take care of them. <Keep reading up on the WWM site concerning nutrient control and export techniques, and you'll see the water chemistry factors improve> My sail fin tang ate out of my hand the other day; I thought that was really cool. <Gotta love that!> If I could just get my leather healthy and nitrate under control and these other things. <Hope I gave you some places to start!> Thank so very much, Teri <My pleasure, Teri! Let us know if we can be of further assistance! Regards, Scott F> Sick (Dead) Toadstool? 3/13/04 Hi all, <Hi Kevin, Adam here. Sorry for the slow reply.> I have spent quite a bit of time looking for an answer to my question but have not run across a specific answer to date. On Feb. 19 (2 weeks+ ago) I received a rock with several Xenia groupings, two types of mushrooms and a toadstool. In bringing the rock home the toadstool seemed to have shed a waxy outer layer and the Xenia appeared 'burnt' in areas. The toadstool extended polyps for a couple of days and then appeared to go dormant and slouch over. <All sounds quite normal after being moved.> The Xenia disintegrated several days later and I cut them back quite close to the base rock. Since then the Xenia have started sprouting new arms throughout all of the areas that were cut back but the toadstool is inactive and the stalk is slowly taking on the colour of a bruise. I enclose two photos. <The coral doesn't look good, but as long as it doesn't start turning to mush or losing tissue, I would tough it out. These animals often take many weeks to recover from insults. If it stays in this state for more than a couple of weeks, despite water changes, etc., I would consider moving it to another tank. I have seen several cases where Sarcophytons suffer for months despite every effort only to quickly recover after being moved to another tank.> Parameters are: SG 1.024 Temp 77 PH 8.2 Amon 0 NO3 0-trace Phos 0-trace Alk 4.5 Calc 300 (attempting to bring up) The tank is a small 38 gallon with approx. 75 lbs. live rock, 12 times volume turnover per hour, 96 watt actinic (13 hrs) & 96 watt 10K (12 hrs). Dosing with strontium & iodine. <I would withhold the Sr and I for a couple of weeks. These are both easily overdosed and the experience of many aquarists who never supplement them proves that with regular partial water changes, they are not necessary.> Is this toadstool gone? How long should I wait to further signs of life? Thanks for the great resource. Kevin <I would perform a couple of 25% water changes, hold the Sr and I and see how it does, but don't give up yet! Best Regards. Adam> Sufferin' Sarcophyton? (Leather Coral Staying Closed) I have a Toadstool with pretty long "tentacles" and I have had it for maybe 3 months. It always came out really nice, then within the last 3 weeks it has not come out at all. I have other Toadstools with no problem and other corals in my tank that are doing fine. Do you have any suggestion what could be wrong. I have a 55 gal tank with 4 65 watt power compacts. Thanks, Karen <Karen, I'm assuming that you're referring to a "Toadstool Leather Coral", Sarcophyton. If this is the coral that you're referring to, I wouldn't worry too much just yet. These corals are well-known for their behavior of "closing up" for periods of time while they shed a waxy organic coating. Sometimes, they can remain closed up for many days. Given good quality water conditions and proper lighting, they will often re-emerge to their former glory. Just make sure that the tissue is still firm and not necrotic. In fact, I just experienced this phenomenon for the first time myself on a two-year-old specimen that I purchased from IPSF. If this is really a cause for concern, do run a check of your basic water parameters, and consider the possibility that some environmental factor might have suddenly changed. Or, there is always the possibility of allelopathic competition (i.e.; "chemical warfare") with another coral nearby. Hopefully, it will simply be another case of the "sloughing" phenomenon discussed above. Keep an eye on things, and don't give up. Good luck! Regards, Scott F> Necrotic Sinularia damage? I have a 3.5” tall Sinularia that that has grown large enough that it has started to rub on a small chunk of rock that sticks up next to it. Where the tissue is rubbing, there is a small black spot appearing, maybe 3/8” long by 1/8” high. The location of this occurrence is about ?” up from where the coral attaches to the rock. <yikes... the black necrosis can be quickly threatening to the coral and perhaps other corals in he tank. o address by cutting/pruning off the excess coral promptly> After perusing the archives, I have found two approaches to take here. 1) Cut the base of the coral, above the damage, straight through and reattach to a new rock. 2) Try to excise the bad material and watch to see if the coral heals ok. What is the current thought on this type of problem? <the latter at first and the former if necessary to follow> Thanks for you time. Don <best regards, Anthony> Will my leather coral pull out of a high temperature incident? HI, I accidentally turned my tank up to 30 degrees centigrade for about 12 hours several days ago. Since then, my leather coral has been drooping and developing holes and it seems to be getting worse rather than better. << Not surprising, but unfortunate. >>Do you think its dying and if so should I remove it as soon as possible? << I would frag a few of the larger branches, in hopes of saving it. I wouldn't just throw it out, as I think many leather corals can make remarkable come backs. >> Thanks << Blundell >> Distressed Leather? (Removing An Aiptasia From a Leather Coral) Greeting WetWeb Crew! <Hi there! Scott F. here tonight!> Kudos to you all, for the time and effort that is put into this site. It helps people like me to better enjoy and appreciate this great hobby. <We're thrilled to be here for you...We have as much fun answering your queries as we do playing with our fish!> I've been reading your site now for about a year and have a 90 gallon marine tank for almost as long. My question is about a beautiful new mushroom leather coral I just purchased -Sarcophyton. The crown is about 4 to 5 inches across and is attached to an approximately 2 inch thick "stalk", about 3 or 4 inches long. On the very bottom the stalk is a piece of rock about the size of a quarter. Wedged in-between this piece of rock and the coral are a couple of nasty Aiptasia. Eeek!! If I am very careful, with a sharp scalpel, or Exacto-knife, could I or should I slice a very thin layer of the coral just above the rock, taking the Aiptasia with it? <I have experienced a similar occurrence with a Sarcophyton, and was surprised how easy it was to remove the Aiptasia without damaging the coral. The base of the Sarcophyton is surprisingly "tough", and you can practically scrape the anemone off of the coral without damaging it.> If so, what treatment should follow? <My best advice is to simply maintain very good water quality after this "procedure"> I have read in Anthony's Coral Propagation book that these corals are quite forgiving. I value your advice. What do you think? Thanks in advance, Brenda. <They are very forgiving! As Anthony and others have implied, you can practically run 'em through a blender and end up with a new coral. However, they do deserve the highest level of care we can offer, so try to be careful when conducting this "operation". Good luck! Regards, Scott F.> Sufferin' Sarcophyton > Hi y'all, > << Hi, Blundell here. >> > In a 6-month old reef tank I have Zoanthids and a Sinularia that are > thriving (twice pruned, still monstrous), but my Sarcophyton elegans > is not feeling well at all. > The problems started when I had to move S. elegans in order to remove a > rock in hopes of catching a suspected mantis shrimp (false alarm, as it > turned out).

The next day (this morning) the coral was in shock and seemed possibly dead. Grey flesh, completely closed up. However the tissue was not soft at all but quite firm. Coral rigor mortis? << It is possible the tissue is contracting, and you can feel the corallites. >> I think the whole animal is dead but in desperation I fragged the whole thing and placed the frags at different locations in the tank. << Not a bad idea.

Paul at your service> My tank is a 20 gallon micro reef that has been running for about 3 months. I've been in the hobby on and off for quite some time. The lighting for this tank consists of 100 watts of 5500k metal halide and 40 watts of actinic. Water parameters are as follows: salinity 1.023-1.024 at 77 degrees F. PH 8.0-8.1 Alkalinity 3.0-3.5 meq/l. Calcium 410-430 ppm. Ammonia, nitrite, nitrate, phosphate levels at '0'. Water circulation is good. <Well, I'll take good as meaning that there is a slight moderate flow over it. Hehheh =)> The tank has about a 3 inch layer of substrate on the bottom , 25 lbs. of live rock and a good protein skimmer. The other corals in the tank; pulsing xenia, green star polyp, Blastomussa, Ricordea mushroom, and 3 clams are all doing very well. <Sounds like an awesome tank> I've had this yellow leather for about 3 weeks. <Yellow corals are sometimes known to be the least hardy in the Sarcophyton species but still a pretty hardy coral in my experience> The 1st week it was doing well, but since then it has not been a happy camper. During the day it is not extended, instead it is shriveled and blotchy looking, and appears to be shedding. <this is very normal for a Sarcophyton to not open and extend its polyps, then shed a mucous coat. This shedding is thought to help keep contaminants and detritus from building up on the crown as well is sometimes related to growth.> I've tried various lighting intensities and played around with water current. I also recently ran carbon for about 24 hours. <Not a bad idea to run carbon most of the time in my opinion. I am thinking just "let it be" "let it be" (great song) Let it go through the shedding process and give it up to two weeks to a month in some cases to come around. Use a soft tooth brush occasionally to keep nuisance algae growth from taking over the coral and to help with the shedding.> Nothing so far has made a difference. I should also add that 10 percent weekly water changes ( natural sea water) from local pet shop, are performed on tank. <Wonderful!> This coral is not being harassed by any of the other inhabitants. <Sounds like you are a very observant and a very Conscientious Marine Aquarist. I have many of the various Sarcophytons in my tanks and have noticed this behavior a great many times and I employ the same technique of waiting and lightly scrubbing the crown occasionally. Usually my corals will come around about a week or two later. Sometimes less sometimes more. If everything you tell me is true, I think your coral will be fine provided the coral itself is just not stressed from collection but even with that it will probably recover. Give it time, that is what I would do. I would do my best to not move or muck with it any further as you could be stressing the coral further. These are very hardy corals for the most part. (especially the captive bred/propagated type.)> I think I've covered everything. Any suggestions would be helpful. Thanks, Chris. <Leave it be and keep me informed of any changes, mate.

Lobophytum Issues - 4/11/03 Greetings guys <Hiya. Paul
doin' my best>... I have a new Lobophytum (purchased 3/23/03) in
my tank. Up until tonight it had been expanded nicely, and a beautiful
golden/pink/brown color, with polyps coming out whenever I checked on
it. Tonight, within about an hour, this coral shrank to about half
it's original size, and turned an equally beautiful shade of
purple. <Does happen if something mucked with it or touched it
recently. Are other corals near? Fish? Sometimes does happen. Since you
sent this a few days ago, has the situation changed at all?> The
only thing that has changed in my tank is that on 4/6, I began to drip
Kalk to help raise my calcium levels. <Could have something to do
with it being so low and then going up, but likely would have noticed a
change in the coral relatively soon after the addition of Kalk not a
few days later. How are ya' doin' on your water changes?>
I've been using B-Ionic (60 ml/day, each part) for a few months.
The tank was started on 10/4/02 with live rock. I began to add fish and
corals on 2/16. They consist of two clowns and a yellow tail damsel.
The other corals are a small candy cane, and some green star polyps.
Water param.s tonight: Temp - 80.2 pH 8.2 SG 1.025 Ammonia 0.0 Nitrite
0.0 Nitrate 0.0 Phosphate 0.0 Calcium 310 <LOW!!!!!> KH 9 <A
little low> A little more background - I'm skimming with an ETSS
800 Gemini with an Iwaki 55RLT. Water is turned over by a T4 (about
1100 gal/hr) plus 2 300 gph power heads pulsed on and off randomly. Any
thoughts about the devils hand that so radically turned? <Hard to
say> Is this a recoverable situation or have I lost it? <very
likely not lost at all. Water changes, time may be all the difference.
Let me know what you find, and how it turns out> Thanks in advance.
<Look to hear from you soon. Thanks for your question and sorry for
the lack of a definitive answer, but hard to say. I would not want to
put it all on the Kalk. My Lobophytum will sometimes change appearance
and shape after tank cleanings, or if something touched it (darn
hermits) etc. Keep an eye on it and let me know if it returns back to
normal. Pablo> D.T. Sarco's acting funny... Hi I have a toadstool leather coral that I bought about 4 days ago. Since I placed it, it has been retracting and coming back every few hours. <First off, never expect a coral (especially a Sarco.) to behave normally in the first week or so as it acclimates to the lighting and the new environment.> Now it is out, but the edge has started to turn white. it's where it looks like it has been cut. <That rock flower anemone looks mighty close to it, could it be getting stung by it?> The store told me to put it in indirect lighting, and low in the tank. Does it need to be moved, or just get used to the lighting? <I'd move it away from the rock flower. You'll need to give it time to acclimate to the lighting again.> Right above it is a green mushroom coral and on the left a rock anemone. could it be that it is to close? I am sending a picture to show where is , Any advice would be a big help. <Good luck with it! -Kevin> Thanks Corey Leather Coral feeling poorly! 6/11/03 Hi Anthony, Hope you and all the crew are well! If you don't mind I have need of your advice again. <cheers, Jenny... good to hear from you> If you remember I asked you a while ago about the hard cancerous patch in the centre of my toadstool leather coral. It had been caused by my two percula clowns constantly swimming and living in the corals polyps. You didn't think at the time that it would be harmful but now there seems to have developed a big deep hole in this calcareous patch and the coral is very unhappy. <interesting... and indeed in need of address.> There are also yellow spots/small patches appearing in places on the coral, these show up clearly because the coral is hardly extending it's polyps now where as before they were always out. The coral is also shrinking in size and I wondered if there is something I can do to stop this determination. <clearly the coral and clowns need to be separated. I personally have never liked clowns in a reef aquarium... they often take even less suitable hosts like LPS corals and kill them. Yet... if you are attached to the clowns, we might simply pull the leather and hope they take a cave next> Everything else in the tank appears to be fine and the only parameter that is not as it should be is the ongoing phosphate problem I have always had and that is gradually diminishing with regular RO water changes. I don't think this is the problem though as this coral has lived happily in this environment for a very long time. <agreed... re: such hardy leathers & phosphate> I think the clowns have caused the damage and am thinking of trading them in but wondered This coral can be revived. <yes... easily> Have you any suggestions that might help? <worst case scenario, the necrotic patches can be cut out with a razor or scalpel> There have been no new additions of either fish or inverts to this tank in the last 6 months and it gets regular water changes of about 15% every 2 weeks. <all good :) > Many Thanks - Jenny P.S Do you know when the new book is going to be dispatched? I'm really looking forward to it arriving! <yes... very soon my friend. They have trucks scheduled to begin shipping it in the US the last week of this month. Hoping you'll see your arrive by airmail to UK early July <G>! Kind regards, Anthony> Leather coral troubles - 4/5/04 Hello- I tried posting this first, but no response..... My leather coral (looks like an upside down mushroom) had been drooping for about a week when I realized that he wasn't going to make it back to upright. I have had him for about a year and a little yellow goby had lived with him the whole time. The goby would perch on top and survey the tank. <this is a Sarcophyton correct?> Anyway, yesterday I took a glove and moved him to get a better look and saw that he was going necrotic on me. <Hmmmmm> I immediately took him out with some tank water and added some iodine all into my girlfriends Tupperware and cut off most of his stalk, which was decomposing. I sewed him up to a rock and he actually looked better with polyps a little extended. <Good move in my opinion> It seems that although the polyps are still extended the death is still spreading. Should I cut him down more? <Hard to say without seeing it but if the necrosis seems to be spreading then cut it about a 1/2 inch above the necrotic area> There were no parasites in his stalk. <Weird. Sounds like one to me> All water parameters are all good. Everything else in the tank is all good, from pulsing xenia to clams... Oh yes, there are no corals next to him or even close to him. <Excellent. Look through our FAQS on our site if you haven't already> The closet inhabitant next to him was a sponge that was about 4" from his base. <Well, never know. Sponges can be aggressive as well but probably not the issue though> thanks, <Good luck ~Paul> Miguelito Arias Ripped Finger Leather stock Bob and/or Crew, Thanks for all the great work you do. I have gained a lot of knowledge through reading through the Q&A and the daily Q&A on the web site. However I was not prepared to come home from work and find that my finger leather has ripped. The two stocks have some what, not completely, ripped apart. <by what action? Important to know.. water quality, age (natural branchlet dropping), imposed attack, etc> The finger leather was on a small frag of rock which I left it on and put it in the substrate, I probably should have attached it to a large rock now in hind sight. <no biggie> One stock of the finger leather is attached to the rock I set it next to, the other is now kind of just dangling there. Picture attached but it is not clear and the battery just died in my digital camera. <alas... no help: not clear> For the stock that is dangling should I cut it from the other stock and find a good rock for it or is there something else I should do. <do cut with sharp scissors or a razor. Then simply stitch with a needle and nylon thread to another rock. Keep handling to a minimum (latex gloves recommended)> The finger leather has grown quite a bit since I purchased it about 5 month ago. As always thanks for your insight and help. TTFN Sean <heehee... ready for my Book of Coral Propagation yet <smile>. With kind regards, Anthony Calfo> Colt coral combustion! Good evening gentleman! A strange thing happened this evening involving a colt coral and I want to get your thoughts... Tonight I noticed that a colt coral in my tank looked deflated around the main stalk. Further observation showed that apparently the branches were separating from the main stalk. <Ahhh, yes... self destruction. Not always as bad as it sounds... sometimes like now perhaps it appears to be strategic. A stress induced strategy of propagation. Animal dissolves at forks in the branches and frags drift to a (hopefully) better spot> Polyps were still extended and it really didn't look that bad. It just looked a little unhappy. When I picked up the coral to check it out, several of the long beautiful branches simply floated away in the current across the aquarium. After my wife stopped screaming (sheesh) I picked up the coral and gave it a closer examination. The "nose" test showed that the coral is not in a state of overall decay and neither are the branches. In the middle of the main stalk, at the point where the branches begin to separate from the main stalk, there was a necrotic ball. I scraped it out very easily and the hole that it left looks very clean. <hmmm... could simply have been an infected spot from minor damage/attack/nibbling> I am planning to mount the loose branches and sew the main stalk back to its' base. <excellent... the best method for attaching this creature> I am surmising that the necrotic spot in the center of the stalk was caused from sediment deposit in that area. <indeed possible, but a sign of poor water movement in the tank of so> I am led to believe this because there was lots of sand in this spot. What do you think? <agreed... a likely possibility> Should I just optimize water conditions and let this incident go? <yes... with close observation and improved water flow> Do you think the branches will make it through this traumatic experience? <easily yes> Possible mitigating factors: B-ionic was started a month ago. <a fine product... be sure to shake vigorously before each use (calcium part stratifies and imbalance of dosing can occur with such liquid products> I add about 60 ml.s a day before the lights come on. The coral was moved at about the same time the B-ionic was started. ammonia- Always 0 nitrite- Always 0 nitrate- Nearly 0 Ca- 280 <definitely a bit low... get into the 300s approaching 400ppm Ca. Kalkwasser will be fine> dKH- about 7.4 ph- 8.0-8.4 lights- 420 watts of VHO. Bulb are a year old and I have ordered new ones. Current configuration: 1 50/50, 1 Aquasun, 1 actinic. Circulation: approximately 1300-1400 gph. <also... colt coral are one of the few coral believed to feed well on phytoplankton. Do consider a planted refugium or liquid supplement to feed this coral for optimal health> Thanks for your time and energy! Dave <our great pleasure. Anthony and WWM> Leather Coral Hi there! My leather coral has been in good
health - showing nice polyp extension and a fair amount of growth as
well. Recently the polyps have contracted and the coral has remained
like that for a number of days now. Everything else in the tank still
seems to be fine - is this normal behavior? <Yes, it is not unusual
for leather-type corals to remain closed for a while and shed a waxy
layer.> If so, how long can I expect it to continue - or do I need
to be concerned? <In a couple more days all should return to normal.
Watch out for that waxy material. You do not want it to fall and settle
on another coral. It is rather noxious.> Your insights will be
greatly appreciated. <You can search for additional information
using the Google search tool on www.WetWebMedia.com> Thanks,
Hilton
Past & Present, Green Finger Coral - 7/14/03 Hello & top of the day! <to you as well my friend> Anthony, I hope you don't mind seeing progressive photos of a green finger coral you helped me "fix" back in January of '03. <a pleasure to see> Do you remember the "Mash 4077th" emergency surgery you talked me thru? <yep... I do recall... carving out the necrotic area at the base as it were> As my very first coral, this beauty has nearly doubled its size twice over! The series of pictures began in mid January & ends 7-13-'03 (the pic with the shrimp on it!) <much appreciation for sharing, mate.... do need to ask you to send non-zipped files, and shrunk in size for us to view/post (low-med res jpegs)> Every time I look at the coral, I want to call ya and say thanks for teaching me all you have in the course of this tank. What better way than to let you see for yourself how the coral is doing! Many thanks, again for your knowledge & willingness to share with the hobby. Peace & incense, Stormbringer. <its truly redeeming and inspiring to hear my friend. Keep on truckin! Anthony> Colt Sickness Dear Mr. Fenner: I was hoping you could shed some light on a problem I have regarding my colt coral. My 125 gallon aquarium has been set up for at least a year now and was doing wonderful! I have a colt coral that has grown beautifully, but around 2 months ago I did a water change of about 25-30% and it has not expanded as much as it used to. <Best to use pre-made, stored replacement water...> Then on top of it not expanding nearly as much, it is now getting white on several branches, not exactly pasty though. Recently I bought a Sarcophyton elegans and it was placed near the colt coral, say 6 inches or so apart at least. <This could be a/the problem...> In your Questions and Answers page they mentioned something like my situation and said it could be chemical warfare between the two. <Yes> Obviously my colt is losing the battle badly now! I know lighting isn't an issue because it expanded beautifully before. Any thoughts on what my next steps are for my colt coral? <At least physically space them more... and add activated carbon to your filter flow path> My nitrates and ammonia are zero, PH is 8.3, and my Salinity is 1.024. Should I sever the white branches and hope for the best in another area? <Not just yet... do you have another tank to move the Sarcophyton to?> I will appreciate any advice you can give me and I thank you in advance! If I left any information additional information out that you would need, I would have no problem providing it. Thank you very much, James <Do at least move the two apart, use a chemical filtrant for organics. Bob Fenner> Colt coral ?'s Hello Mr. Fenner, I hope today finds you well rested, fed, and lively. Oops, I'm talking like you're one of my many pets, or children, or something. <Woof!> My colt coral is weird (for lack of a better term). Let me start off by saying I love this coral. It is tall and proud, and I thought ready for some propagation. I think I jinxed it though b-cuz as soon as I started trying to decide where to cut, I noticed an area that was turning whitish. This area comprises about 5% or less of the entire animal, and does not appear to be sloughing off. Also, it does not appear to bother the animal as it is still looking quite majestic and has full polyp extension. <Might be worthwhile to go ahead with the propagation exercise and discard the apparently mal-affected area.> My H2O tests OK, the only number I'm not sure of is the alkalinity. It is about 9dKH. <This is fine... would be better at 12-15... but no problem> I added some super buffer (alkalinity booster) to bring it back up to acceptable levels (I was told it should be 12-15 dKH) <Oh!> Is this something that commonly happens with colt corals, or should I be concerned for the animals health. <Happens, but I would be concerned...> Also, should I be doing any concentrated feedings for this animal. <Yes... at least once a week, twice is better> I was told by the LFS that it got most nutrition from the PC lighting. On that note, I've got 4X55w PC. I think this is enough. <Mmm, I suggest whoever told you this try to get all their nutrition from standing underneath 4X55 watt PC's> On a different note, I'd like to culture some purposeful macro-algae in my tank but am having a bear of a time locating any locally (Sacramento, CA area). <What? There's a few great stores around there. Do you participate with the local marine club? Here's their link: http://www.marineaquarist.org/ Contact them, ask for names, addresses, directions, advice... there are folks who have a bunch of Macroalgae going themselves in their membership... Mention my name (ho boy!)... as they put up with my visits regularly> If there is anyone in the area who has an abundance I'd love to take a little off their hands. I remember on previous systems having to prune that stuff back weekly. Thank you very much for your feedback. You're a true asset to the marine/FW hobby. <Glad to be here. Bob Fenner> Jason Harris Help (soft coral injury) last night I stupidly moved my new Sarcophyton to a place which I thought would be a better spot I woke up in the morning and it was leaning against a rock and the part that was against the rock had being worn away is this normal? <Normal? Worn away? No> its only being an 1hr or so but should the coral have opened already or could it be dead? <Likely not dead.... maybe move it back to where it was. Bob Fenner> Leather coral Mr. Fenner, I started building a reef setup
about a year and a half ago. I only started stocking my coral in the
last six months. I tried to learn to create a stable environment before
I took a stab at stocking the coral I want. <A wise move> I have
a 125 gallon reef w/ 40gallon refugium and 25 gallon sump, AquaC
skimmer and four MJ powerheads on a wave/light timer. All is going
well. My water is doing wonderful with the help of my Knop Ca reactor.
Ammo. NO2 & NO3 are all zero. I have 150lbs of live rock and a
4" DSB that is very active. <Outstanding> I have as of right
now a frogspawn, hammer (no where near each other), red and blue
mushrooms (no where near anything that they could sting) two open
brains and some pulsing xenia. My next move up was keeping some
leathers. I bought a finger leather as well as a toadstool. I have
heard how it can take quite some time for them to acclimate to a system
after transport. The two I have mentioned I have kept for two months
now. They are mid way in the rock work, getting a moderate to strong
(at times) water flow. I do make sure to have a good food source for
them, and dose with DT often. They are under 384watt PC lights on 12hrs
a day. To be blunt they look like death warmed over. I have attached a
picture of my toadstool leather. I have been told not to move them
because it will cause it to have to acclimate all over again. It made
sense so I stepped back and let them get use to the tank. I am feeling
like a failure at giving the care these corals need to do well. Could
just suggest any course of action I could take to help these leathers?
Or should I sit back and let them be. <Mmm, two months is way long
enough for these soft corals to "recover" from shipping. Do
you add iodide to your water at all? You mention phytoplankton, but do
you feed any meaty foods to these two? I would.> Thank you for your
time and consideration. I hope the attachment will be clear enough for
you to decipher. Take care <Please do read through the scant
materials posted on WetWebMedia.com re Alcyoniids (including the FAQs)
and respond re the feeding and Iodide questions. Be chatting. Bob
Fenner> Another Sarcophyton Question. General Health hi Robert I have had a leather coral for about 3 weeks now and its polyps have partly extended but they look no where near as good as the pictures I see of leather corals on the internet my water levels are all good am I doing anything wrong <Could be... that the animal is just new... could be food, competition, parasitic issues... likely alkalinity, pH, biomineral involvement. Please read over the stinging-celled life sections on WetWebMedia.com Bob Fenner> Sarcophyton woes Hi Bob! <Anthony Calfo in your service> I have had a toadstool leather (appears to be Sarcophyton trocheliophorum) in my 55 gallon tank for about 2 months. It has been happy and healthy as far as I can tell, in fact it is looking better than it did at the fish store! I recently noticed white spots on the trunk. Some are smaller than a dime and others are larger and more oval. I have used a turkey baster to blow off some loose skin in the area, but these spots appear to be spreading. This morning I blew off some algae that was growing at the base and underneath it the trunk was completely white. I took it out of the water and gave it a smell test and everything smells fine, no rotten egg smell. <and the tissue isn't necrotic/eroding?> I also noticed that the white spots appear to turn light brown, and I can blow this off to reveal the white spot underneath. There aren't any of these spots on the top of the coral and the polyps are opening fine. I have read all my books and searched the internet, but I can't find anything that really describes this. <could be the equivalent of a mucosal tunic (shedding/sloughing waste compounds through growth)> It does not appear to be moving across like a front, nor it is it moving rapidly. I noticed the first spots probably about 2-3 weeks ago. Each spot appears to be an isolated spot. Nothing else in the system is affected. Here's the lo-down on the tank: 55 gallon with wet/dry filter, replaced bioballs with live rock. 4 55 watt PC's 2 actinic 2 daylight Ph 8.2 NH3 0 NO2 0 NO3 <5ppm KH 7-8 Ca 400 <do get your Alkalinity up higher...your at the bottom for reef invertebrates...aim for 11-12 dKH> Livestock: 2 cleaner shrimp 3 peppermint shrimp 1 yellow tang 10 blue leg and scarlet crabs 10 Astrea snails 1 serpent star pulsing xenia Sarcophyton elegans Trachyphyllia geoffroyi 2 hairy mushrooms 5 red mushrooms 2 unidentified encrusting corals The open brain sits directly under the leather in question, probably about 5 vertical inches between them. Could there be any chemical warfare going on? <Wow! An important factoid...yes, in fact beyond allelopathy (chemical warfare) you brain can easily reach your leather in the dark of night. You may simply be looking at the mucosal symptoms of burns from the brains night tentacles> The 2 cleaner shrimp have also taken to hanging out on the underside of the leather, could they be picking at it while I am not looking? If I move this coral into my quarantine tank, the lighting in that tank is way low. I think 15 watts regular florescent on a 10 gallon tank. Will this be a problem? Will the shock of moving this coral do more harm than good?? <yes... please move the brain or leather laterally instead (not higher unless gradually. Your brain is stuck in the sand bottom isn't it? Otherwise, there is a very good chance it will die within the year on rock placement> Help Bob, what do I do??? Thanks Leslie <an easy solution. Happy reefing. Anthony> Leather Coral infection Anthony, Working late nights again I
see. <yes... back from a trip and feeling guilty at having
left our friend Steve high and dry solely with e-mail duty
<smile>> Thanks for the advice. I will try cutting in place
and supplementing with iodine as you recommended.
<excellent... it really is a simple and safe maneuver> Running
some AC for a few days after the cut would probably be helpful
too? <absolutely...although there is a minor concern of light
shock to improved water clarity (yellowing agents) if carbon has not
been used for a while (4+ weeks... a bad habit)> Just curious, but
do you have a guess as to what caused this damage, (bad water quality,
fish/crab nibbling,...)? <so many things it could be..
although water quality and aggression from another coral (even if not
touching... called allelopathy. Commonly from hostile LPS corals like
Galaxy, Hammers, bubbles and the like)> Also, thanks for the plug on
your book. <no... thank you for tolerating the shameless
nature of it <wink>> When my wife and I were looking to buy a
good coral book, your book and Borneman's was recommended. We went
with the one with the pretty pics. We're suckers for nice color
reef photos. :-) <understood and agreed... as I am too
<G>> But you can never have too many books, and now that
we've satisfied our pics Jones, we'll be looking to get your
book as well. Thanks! <thank you... best regards, Anthony> Toadstool Leather Plaque Bob, <Anthony Calfo in your service> I have a Toadstool Leather that has always done very well in my aquarium. However, recently I noticed an outbreak of something on the upper part of the “stalk” part of the specimen. It looks like small deposits of a plaque-like substance. It is white in color and porous to the touch. It can be rubbed off but it leaves a white “scar” on the flesh. The Toadstool still stands up straight, but it hasn’t opened its’ little tentacles since I noticed the outbreak. I haven’t been able to find any information that addresses this problem. Please help. Kelli <somewhat general symptom... could be several things. If superficial... could be an incidental sponge or other invertebrate taking residence. If indented, then my suspicion is that it is not pathogenic but rather pest (fish bites, segmented worms, flatworms, etc. nipping and causing necrotic patches). Do observe polyp extension normalcy... if retracted uncommonly for its nature (leathers can have polyps out day and night) pay attention to that photoperiod for a predator. Look closely even with a magnifying glass for camouflaged flatworms. Best regards, Anthony>
