Hey all...
I have not added anything to my tank for many years, and I think I remember seeing this guy a few years back, behind some LR. Well now he's taking to front glass and I have no idea what he is! He is in the un lighted end and seems to open more at night! He has pinkish orange "bubble tips" and a base diameter of a dime with a spread of a 50 cent piece. If any of you have any ideas...

I've got several of them in my tank. I knew what they were, once, but it's very early on a Monday at the moment and my brain's not alive yet.

Ah, Pseudocorynactis carribeorum. I have some too. Closely related to corallimorphians, and about as quickly dividing. They are listed in Delbeek and Sprung, if you have it. Very nice pic, BTW.
