Can you help me ID this macro,
please?
7/7/14
Dear Bob, et al -
I acquired a macro algae from an entire set up that I purchased months
ago.
<A beauty!>
It was a dark blood red wine color macro attached to a rock. At first
glance I thought it was fake, but then realized it was real. I
placed it in my pico. It was doing fine but I
moved it into a refugium that I'd set up
for my 110; i needed macro in there. It's been in the refugium about 4
months now.
Today I was cleaning the refugium and I noticed that this macro now had
a gorgeous blue hue to it. Something I'd not
seen before. I started to search and found
Fauchea sp. to be the two closest match. Then I found a post made
to you from another hobbyist.
http://www.wetwebmedia.com/RedAlgID8.htm -
the first picture looks identical to my macro. I've attached a picture
for you. Please let me know what you think.
<I do concur>
I've been searching for Fauchea sp. for many years. I always thought it
was more blue.
<Mmm, this genus, member species are definitely "change-able"... to
vacillate to more green, blue, purple "depending on circumstances">
I so look forward to your response. Thank you.
Very best regards,
Jan
<And you, Bob Fenner>

Red Algae identification
8/21/13
Dear WWM,
<Chris>
I am attaching a photo of the algae in question. It started as a small
red "flower" shaped bud on a piece of live rock. Over the last four
months it has steadily grown upwards. I have searched the Internet
up and down and have not been able to ID it. I was hoping you could
help.
<Looks to be a Fauchea sp.; a beaut!>
Thanks in advance for all you do.
Chris
<Glad to share, Bob Fenner>

Red bubble algae? 5/6/13
Is this red bubble algae?
<Nope. Appears to be Cyanobacteria aka blue/green algae>
I'm having difficulty identifying it. I also have a small patch of green
of the same looking algae on a different rock. Is it bad? If so, what
can I do to get rid of it? Any little creatures eat it?
<Read more here--

strange growths 12/27/12
Hello,
<Hi Jennifer>
I have 2 strange growths on my live rock that even my
local saltwater shop was not sure about when I showed them the pictures.
I have a 90 gal. bowfront reef tank which I just recently
transferred from a 60 gal. I did not add anything new into the
tank and had the 60 gal established for over 7 yrs.
Upon the transfer and new equipment, a new lamp with VHO, leds and a
timer with dawn, day, dusk, and moon light cycle I recently had an algae
bloom so upon my cleaning up the algae I noticed these odd things on my
rock. What are they? My saltwater guys at the shop, one thought one was
a mushroom which if it is, never seen anything like it and the other
photo a pink sponge which he said to just scrape
it off. But I'm just curious as this growth occurred in a months time.
Ideas?
<The first picture does appear to me a Corallimorph. The second photo is
a Rhodophyta, possibly Kallymenia sp.>
from the back of my tank I found this odd thing.. ?
<Not sure what this is in reference to.>
Thanks for your help!
<Anytime.>

Re: Clarkii Clown Fish Problem, & alg. ID
11/9/12
Hi! I just wanted to update you on my fish that has pop eye. I read your
information on pop-eye but couldn't do a QT tank. I went to my local
specialty fish store and they recommended to use MELAFIX
<... worthless. Would you pour a tea/extract in your own eyes? I hope/trust
not.>
by API. The directions said use it for 7 days and then perform a 25% water
change. We did notice his eye was going down during the use of MELAFIX but
soon after the 7 days it started to bubble up again. Do you recommend to
dose our tank for additional 7 days?
<No>
Another question, during this process of medicating our fish we noticed
these little stringy like things starting to form in our live rock. I feel
like they are spreading. What are they??
<Some sort of red branching algae, a Rhodophyte. Not problematical. Read
here:

and the linked files above. BobF>

Can you help me identify this? 10/11/12
Dear WWM,
<Laura>
I have this purple bubble looking stuff growing on one of my rocks, and
it is getting more prolific. Can anyone identify it?
<Looks to be some sort/species of Botryocladia...>
Should I be concerned?
<Mmm, not much>
I am wondering if it is in the bubble algae family....
<Sea Grapes... some folks call/label as Red Valonia... not as invasive>
Thanks in advance,
Laura Garmizo
<Welcome. Bob Fenner>

Re: Can you help me identify this? 10/11/12
Hi Bob,
<L>
Thanks for such a quick response.
<W>
Would you attempt to remove it? I don't find it unattractive...just
don't want some major epidemic on my hands!
<I'd leave it/this... most Reds come and go of their own accord. B>
Laura
Hi Bob,
Thanks. Will leave alone and continue to marvel at what just "shows
up" on its own in my system!

Algae clarification
3/11/12
Hi Crew,
<Hello Si.>
It's been a long time since I posted on here and asked for
any information from you, although I do still regularly visit the
site (so don't worry :))
I just wanted some algae ID if possible. I think I know what
I'm looking at but just wanted a second opinion, and advice
if I should remove it or not. I attached a couple of pictures,
are they Rhodophyte and a species of Nemastoma?
<Your IDs look spot on and would leave both unless they bother
you aesthetically. I suspect the Rhodophyte would prove difficult
to remove entirely if you ever decided to try. Great looking
Nemastoma sp. by the way! >
Thank you in advance.
Kind Regards
Si

Macroalgae identification 1/27/12
Crew,
<Mich>
I am hoping that you can confirm an identification. This
macroalgae has been growing in our reef for several years under
actinics and metal halides. It's a gorgeous vibrant purple
and I find it more appealing than even the corals. I think
it's a Padina species (slang name onion ring algae),
<Mmm, perhaps w/ an encrusting Red overgrowing it... but I
think more likely this is Peyssonnelia sp. An encrusting Red.
Class Rhodophyceae, Subclass Florideophycidae, Order
Gigartinales, Family Peyssonneliaceae>
but I have been unable to find a picture with a specimen with a
similar color to ours.
Thanks again for the wonderful website!
Michele
<Thank you for sharing. Bob Fenner>

ID Help, Macro or Bubble? 12/14/11
Hello to the good folk of WWM!
<Hello Rey>
Can you help identify what type of Macro Algae or Bubble Algae I
have growing here? Its growing on several different rocks.
They are very small, maybe the size of a small chocolate chip and
shaped like a leaf. Very soft to the touch. Anything to worry
about or will it run its course?
<Some Rhodophytes have also been dubbed by some as Red
Valonia, but your macro algae appears to be a Rhodophyte,
Botryocladia skottsbergii. I'm not sure if they spread like
Valonia so I will ask Bob for his input in this regard.>
<<Not nearly as robust, invasive as Valonia.
RMF>>
Thanks!
<You're welcome. James (Salty Dog)>

Algae ID HELP 12/10/11
Hi all,
<Hey there!>
I am hoping you can help me identify the red (?) algae in the
attached pictures. I have been trying to identify this for some
time with little success. Two of the pictures are actually from
your own pages and are the closest that I have seen. However one
has the algae as unknown, the other as Galaxaura. If it is
Galaxaura what is the most effective means of
control/removal?
<Mmm, same ole... predator search, competition, nutrient
starvation, physical removal... See WWM re Rhodophyte/Red Algae
control>
It is a fragile algae that fragments very easily with loose
fragments sticking to, and colonising a new site very easily. The
fronds seem to exude a 'gel' that may contain tiny pieces
of the algae almost like spores that distribute easily.
<Mmm, yes... alginates... have their many purposes>
It is a nightmare that took over an entire tank and is gaining a
foothold in a new tank. It grows between and on soft and hard
polyps. I have many snails, hermits, an algae blenny, pencil
urchin and hippo tang in the tank but never see any of them
browse it. I have seen the blenny pull mouthfuls of it but that
seems to aid distribution rather than control it. The tang will
eat fragments it finds in the water column but I have never seen
it browse.
<Again, peruse WWM, the Net, in-print literature... as you
might surmise, there are organisms that eat all organisms...
Perhaps a Siganid, if it will go in your system>
Nitrate and phosphate are both zero, I use biopellets, and Chaeto
in a reverse lit refugium to control nutrients.
<Mmm... make that Mmmm, I'd be looking for a good
predator... likely modifying your water chemistry (gone over on
WWM) to severely deny HPO4 to the pest>
I really am desperate to find a solution before it gets out of
control again. This is a recently set up tank but this algae
growth is not part of the cycling process. Filamentous, Cyano and
diatoms have all come and gone and it looks like this is here for
the long haul.
<Ugh, no fun>
If it gets to the same proportions as in my previous tank I
really think I ill get out of saltwater altogether, it is too
sickening to see corals smothered by this as the tank turns into
a red/brown mass.
Hoping you can help,
David
<I can... please send along a better (more-resolved image...)
even a microscopic one if you can. Don't give up... often
some aspect, self-limits such outbreaks... Bob Fenner>

Re: Algae ID HELP 12/10/11
Hi Bob,
<Big D!>
Many thanks for your prompt reply, coincidentally I am taking a day
trip to my not-so-LFS
<Heeee!>
tomorrow and a Foxface Rabbitfish Siganus vulpinus is top of my
list. My old tank was too small to allow me to use such fish as a
control but I'm hoping they can do a job in this tank.
<Ah good>
I could also put a phosphate reactor in place to try and limit
availability of HPO4.
<Ehh, just boosting pH via Kalk will do all you want/need to do
here... Remove your Chaeto for the day...>
I often question myself as to the usefulness of nitrate and
phosphate tests.
<Mmm, are rationale "windows" into looking at what
is/may be going on in a system... BUT only w/ understanding of
their implications and short-comings>
Surely a kit could give a zero reading due to the fact that the
tank is a mass of problem macroalgae while the aquarist is
thinking, "Well done me!, so why can't I get rid of this
algae".
<Mmm, a valuable lesson here for you (and many others) re the
real nature of the universe... Uhh, it's not all that
"discrete"... but more like calculus vs. deterministic
arithmetic... In your "real time", it may appear that
there is insufficient nutrient to allow such a situation... In some
sort of reality, the pest algae IS the nutrient... i.e., it's
very likely scarfing/scavenging all up... One mechanism for
limiting (nee teleologically intended here) competition,
eh?>
Again, thanks for your time,
David
<And you for yours. BobF> |
