What could be capable of eating an entire zoa/paly in one night? The polyp was perfect yesterday then gone with no trace. Not even I am that good with a razor blade...
Well that explains it. There is just one in the tank right now. I knew he was suspect with his speckled pattern but I let him go just to give the guy a chance. Time to get him out before he splits.
Yeah I had two Asterina like that. I thought they were so cool I let them mow down my no name green zoanthids. It was a big colony, and Dino is what finally did the colony in, but before the Asterina would just munch away.
