pick sack thing?? 02/09/09
Since moving my tank, these strange pink sack like things appear
in my tank at random intervals. When I scoop them with a net they
fall apart. I assume it is some sort of waste material, but can
not figure out where it comes
from. They are rather large 1-3 inches in length. Tank is 170
gallon FOWLR six line grouper, wolf eel, snowflake eel, dog face
puffer, saddle back grouper.
Thanks in advance
<Mmm, given their shape, the falling-apart behavior... my best
guess is that these are fecal pellets... What do you feed these
fishes?

 "Heighhhhdy
hoooe!" |
Re: pick sack thing?? 02/09/09
Thank you for the response, They eat frozen or freeze dried
krill.
<Ahhh! Am more convinced that this is waste material...
Euphausiids often "come out" like this color and texture
wise... I'd just vacuum out. Cheers,

Re: Algae ID?! 02/06/09
Hi Minh,
<Hello Brian.>
I apologize! I thought that I had sent you the pics. I did look
on your site (http://www.wetwebmedia.com/trialalgaeid.htm) and a
few you mentioned below but still can't find anything that is
similar to it. Hope these pics are clear enough to get a good
view! Please let me know!
<I'm sorry but I still don't see any attachment with
this email. Could you try to resend the message with the pictures
attached?>
Thanks again for your help!
-Brian
<Cheers, Minh Huynh.>
Re: Algae ID?! 02/06/09
Ugggghh! Very Sorry Minh!
Here are some links to them in case they are getting stripped
off.

http://i258.photobucket.com/albums/hh246/networkfishman/algae%20prob/IMG00033.jpg
Sorry for the inconvenience!! I really apologize!!!
<No problem, Brian. Technology can be so unpredictable. Well,
I am finally able to see this algae and it is quite an
interesting case! If it is indeed a type of algae, I don't
believe I have seen this algal variant before. A typical long and
white algae would be Acanthophora spicifera
(http://www.reeflex.net/tiere/1619_Acanthophora_spicifera%20.htm)
and the growth in your tank is quite different. Another
possibility is a form of sponge like the Carteriospongia
vermifera
(http://www.reeflex.net/tiere/2202_Carteriospongia_vermifera%2002.htm).
I will have to check with my colleagues and other resources to
verify and get back to you.>
Thanks again,
-Brian
<You're welcome. Minh Huynh.><<RMF's
vote's on a Poriferan>>

Unknown hitchhiker; Hydroids -- 02/01/09
I have a BioCube 14 standard setup (no modifications). I am using
20 # live sand and 13 # of live rock. My water test are nh 0,
nitrites 0 ,nitrates 10, Cal 400, dKH 16 ,phos. .25 ph 8.2 this is
what my test have been showing for about 3 weeks now. I have be
doing 20 % water changes once a week since the nh and nitrites were
0.
I added 2 clowns and a xenia and green star polyps. I notice the
GSP had something attached to the bottom of it . looks like an
antennae. There are a total of 3 of these antennae attached one is
about an inch and a half the others are maybe 1/2 inch. They are
non mobile stiff straight the color is a pinkish brown .I have been
on 3 different forums with no luck on the ID. I was hoping you
could ID for me. I will attach a pic for you. Thank you. Anna
<Hello Anna. Looks like branched hydroids. Please have a look
here: http://www.wetwebmedia.com/hydrozoans.htm . Difficult to see
more detail on a usual photograph. Most have a strong sting, better
do not touch with bare hands. It's possible they will not live
very long in your tank, will depend on the available plankton.
Cheers, Marco.> |

Re: unknown
hitchhiker 2/1/09
I apologize I sent the wrong photo. I will attach the
correct photo.
sorry again, Anna
<Mmh... looks like a type plastic needles used by the
hobbyist or shop to fix the Clavulariid. Will leave this
email for other crew members to see and have a guess.
Marco.>

Re: unknown hitchhiker
2/1/09
I apologize I sent the wrong photo. I will attach the correct
photo. sorry again , Anna.
<Me again, probably hit the send button too early. Can you
get the them out, see if they are plastic? Do the smaller
ones have the exactly same length or are all 3 different?
Some sea urchin spines look quite similar, compare
http://www.kreidefossilien.de/assets/images/galleries/182/pseudodiadema_sp_.jpg
. Cheers, Marco.> |
Re: BobF asking... what is this?
2/2/09
Lynn... Howsit? Marco responded ayer to
this person re something in their tank, and they've sent
along a new pic... I can't put my finger on what these
three prominences are she's referring to... Can you? Have
put in your in-folder.
BobF.
Doing good this morning, Bob! I just checked out the photo.
You know what those look like - urchin spines - with the
attachments/bases visible on the ends and the tips buried in
whatever that thing is.
-Lynn
<D'oh! Of course! Maybe just some BGA overgrowing...
Thank you Lynn. BobF>
You betcha! I'm glad I was able to help. :-)
Take care and have a great week,
-Lynn
<Thanks Lynn. You as well. BobF> |

Mystery stuff growing in my established marine tank --
02/01/09
Hi, I tried to search through all I could at your sight and
didn't come across anything I could find that would describe
what this is in my tank. I attached 3 pictures, 2 of the one and
1 of the other. Here is what I have:
1.This white, almost leather looking stuff that has LONG stringy,
root looking things growing all off it and around it. Doesn't
seem to move. I took really great pictures so someone could help.
I have this same white or off white leather looking globs on
other rocks but the stringy stuff isn't growing there...all
is gathered in the area you see in the picture.
<This is a sponge... a Poriferan... See WWM re... not
deleterious>
2.The second question is this cotton ball looking growth, it
actually reminds me of a dandy lion after you blow the stuff off
of it. Its round in shape with short spike things all around it.
Doesn't move either. The rock in the tank has been in my tank
for years and these things are just now showing up. I can't
think of any reason for the changes at all.
<Mmm, how large is this? It looks like an Urchin of some
sort... may not move much... also not harmful...>
Any help to point me in the right direction would be awesome!
Thanks! Leann
<Enjoy them! The sponge can be "cut back", the
"Urchin" removed entirely if they bother you. Bob
Fenner>

Re: Mystery stuff growing in my
established marine tank 2/1/09
Thanks! As far as size to the cotton ball, spiky looking
things I sent a picture of, its about the size of a paint
ball....it doesn't ever move, I re-attached the picture
just in case you still didn't have it. Are there growths
on tanks that look like that?
FWIW, I think it's just a sponge... - Sara M.
<Mmm, yes... Am changing my guess to another Sponge.
