I kept a couple about 20 years ago. I'd have them again if I could find them. They ignored tankmates but, fed on rosy reds. Also ate earthworms, blood/blackworms, pellets, wafers, etc. Not as active as regular clowns but, not fearful of being out in the open, either. Kept them in a 78F tank until having to give them up to transfer back to sea duty.
