ID - Baby RBTA?

[jnowell]

Hi everyone, I got 10lbs. of GARF Grunge a few months back, and tons of life has crawled up out of it, polyps, Zoas, starfish, etc. Recently, I noticed this little guy growing up out of an empty shell.

It has kind of a purple/red center, and a slit for a mouth (similar to my LTA). The disk is slightly smaller than a dime. Some of the tentacles are approaching 1.5" when it's fully extended. There are little white balls on the ends of the clear tentacles too. I can;t really see the base (foot) because it is inside the shell. If I had to hazard a guess, I would say it was a baby Rose Bubble Tip Anenome. If so, do the young ones require any special care, and if not, what the heck is this?

Thanks!

Pseudocorynactis spp.

Actually in the mushroom coral family and NOT an anemone.

They don't like/require light and are relatively harmless. You can target feed them for faster growth and reproduction.

I second that ID: a corallimorpharian... and so-called "ball anemone" of the oft-cited genus Pseudocorynactis.

It's quite common with Atlantic aquacultured live rock and other substrates pulled from there. See images and a tidbit of more info on the in the fabulous Humman dive series books (Reef Creatures, Reef Corals, Reef Fishes)
