Hey bud. I would consider adding another clown of the same species. they really need a partner so they can go and explore together and also interact with. i have two Black Snowflake that was lucky enough to get a pair that was already bonded for like 90 bucks. These two really love each other and never separate in the tank.love those two and because of them i decided to have QT tank. I have a red bubble-tip anemone in tank that hasn't moved and i haven't seen them interact with it . Hopefully they get acquainted later on lol. Bottom line, get him a partner a bit smaller but not too small because at the beginning they will fight to figure out who's the boss. they will figure out the sex themselves later on.
