Can you identify the animal in the attached photo? Was told it is an "invertabrate", but can't seem to get any further info.

Thanks!!

nah, its not xenia. its a sea pen. genus Cavernularia. since this thread is a few months old I'd bet the animal is dead by now, unfortunetly they are tough to keep.

Fishome, I think you are right....I should have looked closer and seen the body off to the right and that it was laying flat threw me off as i don't think that is standard behavior for sea pens.

Cavernularia obesa

I agree, filter feeders do not seem to do well in reef tanks.

yea i'm sure its lieing flat for 2 reasons. 1 its not happy and 2 it should have a very deep sand bed.
