Live Rock Hitchhiker IDs (Corallimorph and
Red Alga) – 05/07/07
I purchased a new piece of live rock and a few weeks later found
this growing on a piece of dried out plate coral.
<<Neat>>
The plate was totally bleached out and dead when it went into the
tank. These appear to be some sort of mushrooms and I have no idea what
the red stuff is in the other picture.
<<Mmm yes, perhaps a Ricordea species...and the “red stuff” is a
Rhodophyte though what species it is I don’t know...perhaps if you have
a look around at algaebase.org...>>
It started out with just one small creature and has now expanded to at
least 20.
<<Fast grower, eh>>
They are now about 6 months old.
<<Mmm, ok...not atypical for Corallimorphs>>
There is clearly a mouth in the middle of each one. The stalk is soft
and will extend out. They look like Blastomussa on the top surface, but
as I said the stalks extend and are soft.
<<Yes...like Ricordea>>
When they are fully contracted the "fleshy" parts will look pink as can
be seen in some of the smaller ones. They can also blow up much larger
than this like an anemone. <<Typical Corallimorph behavior>>
The red stuff also appeared when the new rock was put in. It has now
spread over about 40% of this rock. It is made up of many small -3mm or
so lobes. These lobes are vertically flat.
<<The red alga “may” become problematic/spread more than you like. If
this happens, your best bet for controlling it (short of manual
extraction) will be an urchin species. Mespilia globulus is a good
choice for smaller systems or a Diadema species for large (100g +)
tanks...but be aware it has been my experience the latter will also
sometimes graze on Acroporids. EricR>> |

Unknown hitchhiker White Ball Corallimorph (Pseudocorynactis sp.)
4/27/07
<Hi Jim, Mich here.>
Would you advise your best opinion as to what this creature is.
<Yes, looks to be a White Ball Corallimorph (Pseudocorynactis sp.)>
I found it on an empty snail shell in my tank.
<Likely a hitchhiker.>
One opinion from another forum was that it is a bleached majano anemone.
<No. It is not a Majano anemone. Is a lucky addition to your tank. You
might try offering this coral finely chopped fish at night or when the
tentacles are extended. They are not common in captivity so enjoy
it!>
Thanks for any help.
<You're welcome! Mich>

Mushroom coral-can you please identify, Elephant Ear mushroom
(Rhodactis spp.) - 02/15/07
Hello, Peter from Bodmin Cornwall UK
<Hi there Peter from Bodmin Cornwall UK, Mich here from the Pocono
Mountain of Pennsylvania USA>
Greetings, and thank you for your advise on using Aerial
polystyrene sheets some time ago - I've had no problems.
<Glad to hear of your success>
I attach a photo' of an acquirement from a piece of living rock
(origin unknown) - it appeared as a growth approximately 5mm across
within about two weeks after installing the rock into my tank about two
& a half years ago. The picture was taken one year ago. The picture was
taken by 'flash' on a digital camera with the resultant colouring.
Viewed from the tank under blue actinic &
white lighting it is a soft 'terra cotta' colour-viewed from above a
silvery blue. It has thick stems of about 25 mm & the 'florets' of
which there are now seven are in the region of 15-20cm across. It
obviously likes my tank conditions - it is positioned in the middle of
the tank - about 20cm from the
surface. Can you please identify this for me.
<Yes, looks like an Elephant Ear mushroom (Rhodactis spp.) and a
potential fish eater so be aware. Can read more here:
http://www.wetwebmedia.com/corallim.htm >
Thanking you in anticipation
<You are welcome! -Mich>
Peter Heath
PS I have just purchased The Conscientious Marine Aquarist - a treasure
chest of information -no matter how much you think you already know.
<I wholeheartedly agree!> |

Mushroom ID 2/13/07 Elephant Ear mushroom (Rhodactis spp.)
2/14/07
Hi Crew,
<Greetings! Mich with you tonight.>
I have this large mushroom and would like to know exactly what it is
since there seems to be a debate in a local group as to whether it is
even a mushroom.
<A mushroom indeed, of the order Corallimorpharia.>
It was the size of a quarter when I got it a few months ago and now it
is about 5 inches across and my tank is just a 10 gallon.
<Growing quickly!>
It has a green background. It has a white mouth and long tan colored
tentacles that are very irregular with branches. Sometimes it shrinks
and the green is very intense as it is in this picture. Other times it
spreads out. It looks like there is a light on behind it. At times it
will roll up like a balloon with the underside being the outside of the
balloon. It does this mostly at night. Anyway here is a picture.
<Looks like an Elephant Ear mushroom (Rhodactis spp.) and a potential
fish eater so be aware. Can read more here:

Cheers! -Mich> |

Re: another Anemone ID... Corallimorph? - 1/22/07
Hi Bob,
I was wondering if there is a defining characteristic of ... Corallimorph?
<Yes... posted on our coverage of the Phylum (Cnidaria)
I watched this animal puff up his foot and go for a walk last night.
<!? Atypical!>
I also fed him and he felt sticky, which I imagined a ... Corallimorph would
be more slippery like a mushroom.
<Corallimorphs are mushrooms...>
My clowns were immediately drawn to the animal which I guess is why I am
skeptical of the fact that it would be
classified in the mushroom family.
<Clowns will/do associate with all sorts of Anthozoans...>
I understand that the clowns will host just about anything but they were very
vigorous about acclimating to their new home.
Again thanks,
Dale
<This could indeed be an actinarian per your original query... but morphically
atypical due to present circumstances... its position, lighting, circulation...
perhaps the tentacles will elongate with time, movement. Bob Fenner>
Nuisance anemone
1/17/06
Dear WWM crew,
<Hi Julia, Mich with you today.>
First of all, thank you all for any previous advice you have given me over the
last couple of years. Thank you for the fabulous web site. You guys (and gals)
are awesome!
<Thank you for your most kind words!>
I have a quick ID question for you. I know you guys need to see pictures to
know for sure, but a picture is not feasible right now.
<Would be most helpful.>
I just bought some "used" liverock and it has these tiny anemones on it. They
do not look like Aiptasia to me. They look more like Majano, except they are
perfectly clear, no tint of color whatsoever. Just the very tips of the
tentacles are whitish (and slightly swollen, from what I can tell). Can they be
bleached Majano, or is this another species? The outer tentacles are also a
little longer than what I am used to in Majano (almost like they are half way
between Aiptasia and Majano anemone, or they look almost like a clear dwarf sun
coral polyp, just shape-wise that is). Does this ring a bell?
<Really impossible to tell with out a photo. Many possibilities here, including
many desirable creatures, could even be something like a orange ball
Corallimorph (Pseudocorynactis caribbeorum)...do a google image search on this.>
And should I do anything about these? Until now I have had NO pest anemones (my
liverock was reseeded from scratch, so to speak), but if these guys are "bad" I
would rather not give them the chance to spread.
<Understandable, but if they are desirable I don't want to tell you to eradicate
them... thus the reason we ask for images.>
My tank is not terribly nutrient rich, but as it is a softie tank I do not want
to get it too clean :)
<I hear you.>
Thank you all again for your help and have a wonderful week :)
<Welcome and wishing you the same. -Mich>
Sincerely,
Julia.
Re: Nuisance Anemone...No, Desirable Hitchhiker... Pseudocorynactis
caribbeorum 1/19/07
Mich,
You are amazing :)
<Heehe! And you are funny!>
I did an image search on google, just like you told me, and Pseudocorynactis
caribbeorum indeed does look like my guy :).
<Lucky you! It is not sold in the hobby that I'm aware of.>
Except that mine has white balls, not orange.
<Yep.>
I guess I will have to do a bit of research on these creatures since I have
never ever encountered them.
<Hitchhiking nocturnal filter feeders.>
I just found a picture of it on your web site (I am attaching it, I hope you
don't mind), that is almost exactly like mine.
<Very good.>
Thank you so much and have a great day!
<Welcome and the same to you! -Mich>

Strawberry Anemone 3/24/06
Oh, I thought I'd include a pic of what I've been calling the
"strawberry anemone" from what I've found on your site and others.
Any input? Oh...and I also noticed a little frag of a purple
Ricordea that we thought we'd completely lost during a past
move...just thought I'd share a happy thought. Branon.
<<No real input other than the fact that they are neat critters. If
you want it to survive and thrive, make sure it gets frequent small
meals of meaty food. Glad to hear you rediscovered a presumed
missing critter! Best Regards. AdamC.>> |
