I have attached a picture, and was wondering if this was
<Appears to be, yes>
Also, I read that the Red Legged Hermit Crab consumes Aiptasia,
does this include the dwarf red legged hermit crab?
<Mmm, neither usually do>
I have also included a picture of a colony of brownish things on
my live rock. Is this also a type of anemone?
<Perhaps... more likely a Hydrozoan or Zoanthid>
They don't look like feathers, but they look too thin to be
an anemone. Any help would be appreciated, I don't want to do
anything until I know for sure what I am dealing with.
<Mmm, please do send along a better resolved image if you
can... And if/when you have time, peruse WWM re these groups of
Cnidarians. Bob Fenner>
So I've looked everywhere I can think and posted this picture
on quite a few forums. The only response I've gotten is
I've had those before and don't agree.
has a flat, round, purple base with short, brownish, green tipped
tentacles. It closes in on it's self whenever touched or at
I know it's not the best picture but if you don't know
what it is exactly, then can you tell me at least that it's
NOT a pest anemone I need to get out?!
Thanks a ton for your help
<Is there a hard skeleton beneath? This is likely a
"single polyp stony coral"... likely a Caryophylliid.
Put this string of words in WWM's search tool... or the
Net's... and read the cached views. Bob Fenner>
Re: Aiptasia?? 4/5/11
I looked around a little and found a picture of a larger specimen
but almost identical to mine. I'll have to let it grow more
to be sure but probably a match. Thanks again
<I would keep this organism... not harmful, likely to be of
interest. Cheers, BobF>
Hi, I am not able to find this organism. I bought live rock and
it was included on it. I have no idea what it is.
<Nor do we. You didn't attach an image. Do remember, we
ask people to resize images to about 500 KB; don't send
multi-megabyte images straight from your camera please! Cheers,

coral identification problem 1/19/11
Sir or Ma'am,
I have been searching for the identification of this coral for
<Mmm, I don't think this is a coral... not an Alcyonacean
or Scleractinian definitely>
I have posted pics of it several times on reef central and no one
seems to have a good answer.
If you guys can help it would be greatly appreciated.
<From the gross shape, "tentacles" I suspect you
have a Pennatulacean here... a Sea Pen. Bob Fenner>

<Welcome Jonah. Please send along any further ID, pertinent
husbandry info. you gather. BobF>
Re: coral identification problem 2/14/11
Posted this again on RC and some suggested pulsing leather. That
sounds like what I was told by the guy I got the frag from.
<Mmm, had to look this up myself... Pulsing soft corals are
Xeniids, Leathers Alcyoniids... I don't see an explanation of
taxonomic affinity... Is this supposedly a Sinularia sp.? You got

Ok. Just heard back from the guy I got it from. Pumping
Club-tipped anemone or majano? 1/2/11
I initially thought these were majanos, but I think they look
more like club-tipped anemones. They're not green, except for
the middle row of tips under actinics. The rest are colorless
with white tips. The diameter is about a half inch. I'd be
interested in your opinion.
<Mmm, this might be the beginning of a Euphylliid... or even a
Corallimorpharian (see the Net re Pseudocorynactis... pix).
Can't tell from this image in other words if indeed this is
an anemone! Cheers, Bob Fenner>
Re: Club-tipped anemone or majano? 1/3/11
Based on similar pics on the Internet, I'd agree that
it's a Pseudocorynactis (white ball).
Thanks for helping to confirm.
<Certainly welcome Dan! BobF>
Coral Identification 12/29/10
I have searched on Google as well as asked several forums for an
ID on the attached coral. But, everyone that has look has been
stumped. The coral does not seem to have a skeleton but, is
similar to a hairy or frilly mushroom.
<This is Rhodactis. Search on Google re: under
I have noticed that this coral has several mouths though, as
opposed to the mushrooms which only have one.
<Is splitting/ reproducing by fission>
Any help would be greatly
