red macroalgae
8/31/09
Can you tell me the actual and or common name and care needs for this
macroalgae?
Thank you,
Catherine Kresge
red macroalgae. phylum- Rhodophyta. family- Gelidiaceae. From the Indo
Pacific
<Mmm, looks like Gelidium serrulatum to me; not from Indo... use the
name on the Net to look up its husbandry per your setting/system.

Green Star / Gorgonia ID please?
7/8/09
Hi there crew! My first time writing in! :)
I have attached a photo of some "Green Star Polyps" that I bought several
years ago. I bought it because I have never seen GSP quite like this type,
nor have I seen it again. It is indeed ULTRA neon. I have hunted around to
try to find a specie name, but I have yet to be able to even figure out the
genus. Could you please possibly shed some light?
<Is a beauty... likely a Pachyclavularia violacea species... they occur in
different colours>
Oh, it is encrusting, and grows in fingers along the surface. I also
attached a photo of it's growth pattern (as seen from the back side of the
glass).
Thank you so much!
Mindy
<Mmm, your second image is a Rhodophyte (red algae) in a reproductive
phase... the bumpy bits at the top. Bob Fenner>

Re: Green Star / Gorgonia ID
please? 7/8/09
Hi Bob,
<Mindy!>
Thank you so much for your reply!! So, it's just "basic" GSP, but a
different color? How boring. Hahaha! I'm kidding. Here I thought it was
different since the shape of the stars is so much different.
That second photo is actually of the GSP growing on the glass. I'm
pretty sure there is no algae growing with it. The photo is taken from
the underside of the GSP mat. When it first starts growing the mat isn't
very purple, but purples up as it ages. If you look real closely you can
see the green stars peeking out from the other side. I can take photos
from a different angle if you would like. :)
Cheers!
Mindy
<Geez, I've got to wake up a bit more before responding to queries... My
eyes are getting "sunburned" down here in Key Largo. Cheers, BobF>

Algae ID: 4/2/2009
Hello guys,
<Hi Adam>
Looking to identify a miscellaneous algae that has been in one of my fuge's
for a very long time. The fuge is connected into my 120 gallon reef and I am
slowly closing the 120 down and placing its inhabitants in my new 800 gallon
system.
<Nice setup!>
I wanted to identify this algae to avoid potential problems as I think it
may be Dictyota?
<Hmm... No>
The only algaes purposely placed in this fuge were Chaeto, a small fragment
(from a previously set up fuge) of what was sold to me as Gracilaria, and
some Ochtodes. I have moved some of the Chaeto over to the big tank already
and screened it for anything other than pods, worms etc. . and hope I have
done a good job at keeping anything un wanted out. Any help on an ID for
this algae would be much appreciated.
<Looks like a Fauchea sp. or a Gracilaria sp. In either case, definitely not
a nuisance algae, and is quite attractive when allowed to grow.>

Nuisance Algae or Sea Fan?? 2/16/09
Hi Crew:
<Hi
Bonnie, Mich here.>
Attached is a picture that I hope you can
identify.
<Me too!>
My reef tank is 3 1/2 years old. I have a
deep 5" sandbed made up of crushed coral. I know, I know.....it
takes a bit more maintenance than a substrate made of true sand, but
I am diligent in stirring up the crushed coral a couple times a week
and vacuuming the bed about every 3rd week.
<Good husbandry can
makes all the difference!>
I recently removed about an inch of
the top substrate and replaced it with new crushed coral.
<You
are wise, this will help your buffering capacity.>
After I did
this replacement, about 3 weeks later, I noticed this maroon,
feathery growth.
<May or may not be related.>
It has
continued to grow and is quite pretty.
<I agree!>
I thought,
originally, it must be some type of sea fan.
<Mmm, no.>
However, I just want to make sure and not have some nuisance algae
growing and getting out of control.
<Does look like a Rhodophyte
to me, but that certainly doesn't make it a nuisance! If it was
mine, I would encourage it to grow.>
It's very soft and feathery.
Can you tell me what this is?
<The photo is not clear enough for
me to tell to much beyond it's a red algae, but it sure is a
beauty!>
Thanks for your help!
<Welcome!>

Re: Nuisance Algae or Sea Fan?? 2/16/08
Hi
Mich,
<Hi Bonnie,>
Thanks so much for your response.
<Welcome, I'm happy to help.>
You are exactly right in your
identification. Once you told me that it was more than likely a
Rhodophyte, I did a search by that name. Someone had written in on
8/3/06 with a very clear picture of it. That one is a bit more
translucent than mine, but that is what it is for sure!
<Great!>
Since it's so pretty, and you've encouraged me to let it grow, I
will see what becomes of it.
<Excellent!>
Thanks, again!
<You are most welcome!>

Identification 12/21/08
Hello:
You have
always been helpful in the past...
<Glad to be>
Can anyone
tell me what this is growing on my colony of green polyps. I have
seen a this "plant" before when I first bought my LR 4 years ago,
but it never grew like this is growing!
Hoping it is not a bag
thing or evil plant...
Thanks!
<Mmm, is a Red Algae, a
Rhodophyte... not evil... Likely a Fauchea sp.
Please see the
Net re or here on WWM: http://wetwebmedia.com/redalgae.htm
I'd
enjoy it... will likely be "discovered" by life in your system, and
consumed... Or some condition, variable change there... that limits
its growth, being. Not likely to "run amok".
Bob Fenner, who on
the other hand... is very likely to do so> |

Animal, vegetable, or mineral? - 12/20/2008
This unusual
creature (plant?) below is a hitchhiker on a Corallimorph colony (which
seem to be Rhodactis, you can see in the pic to the right).
Photo
links are below, feel free to download them from the link if you want to
post them.
I have no clue what this is. I, and a few other reefers,
suspect it's a form of coralline algae.
<From the picture, I concur,
although it is hard to see any diagnostic characters.>
So, I browsed
all of your coralline ID and red algae pages and didn't run across
anything similar.
It is about 1/2" diameter, and never moves,
extends any form of polyp or sweeper (even night), or does any other
thing similar to a coral. It is rock hard, just like coralline algae. I
can't comment on how fast it grows, I've only had it two weeks.
But
it looks so much like a mushroom Corallimorph that it's just plain
weird. It seems to have an oral disc. Perhaps it's just some strange
coincidence and the algae is conforming to the shape of the rock
underneath.
<Sure, to some extend, environment and DNA make it look
like it does.>
I have never seen coralline algae that was brick red
like this, with the yellow striations. Very cool looking, I hope it
grows.
<Indeed.>
So I am at a loss. Coral? Algae? Bryozoan?
Republican? Democrat?
Any ideas?
<One of the over 600 species of
the order Corallinales as shown on
http://www.algaebase.org/browse/taxonomy/?id=4621 . >
Thanks!

<Cheers, Marco.> | 
Likely Peysonniella sp., a Rhodophyte, Red algae. RMF.
Re: More re: Animal, vegetable, or mineral? 12/20/08
Peysonniella squamaria is what I had suggested to me by a friend on
a reefkeeping forum. I did a Google image search, and I could find
examples of this specie with the right colors (red and yellow), but
none of them with this shape and pattern.
<Is highly variable...
mostly shallow concaves, to overlapping sheets>
Not that
shape/pattern really means much with a random-growth alga like this.
Thanks for the help! I hope this stuff grows all over the tank, it's
very nice.
Matt
<Is a beauty... Some of my pix here:
