when my rbta split i thought it was only 1 clone. but i found a small little dude with only 2 tentacles and no mouth. don't know how that happened, because i thought it needed a mouth, but i guess not. he has been in my extra tank and still growing. has a mouth now too. your anemone could have popped that little piece off.

and i agree with jimd, that mh is probably the way to go.

so, have you been able to feed it yet? he didn't look bad in the pics, maybe it was just getting used to your tank.
