what is this on the rock

[keith gray]

I know this pic is not a good clear one but this thing growing on my rock is in a place that I can not get a good picture. It is to the left and looks like some kind of weed or something. It does not look like any aptasia I have seen before so I just wondered if it something good or bad. I think the other two things on this rock might be sponges any opiniono on these as well is welcome.

aiptasia - do you have any fish that will eat shrimp? I had some of this and added true peppermint shrimp and they ate it within 2 days

I very well could be wrong but it looks like aiptasia to me. I had the same thing a few weeks after I started my 120. I bought 3 (true) peppermint shrimp and it was all gone in a couple of days.

The aptasia I have seen in the past does not have the 'furry" looking arms for lack of a better term. The arms extending almost look like seaweed texture. It has been this size since I got this rock. It does not change shape or size it appears.
Any one else have an opinoin ??!!

Do you know where the rock came from?
Looks like a corkscrew anemone to me. Bartholomea annulata

Same thing as corkscrew, one of the reasons I like to include the Latin name when possible.

I bought this rock at my LFS. I did not think it was aptasia = it has no shaft or trunk so to speak.
I am not familiar with corkscrew anenome. Is this something that is not a pest- there are no more of these in my tank.
Is this OK to leave there ?

 

[spanko]

I don't know much about them. I do know they are a member of the Aiptasiidae family. Also the Curly-Cue Anemone is a carnivore, and will consume fish, mussels, and crustacean meat.

If it is aggressive I would hate for it to hurt one of my fish or invertabrates.
DO you think Aptasia- X will kill it ?

 

[spanko]

I do think so.
