Any suggestions for large active colorful fish for 220G Fowlr that will not rock my my current fishes (list included)?

I'm still going to give the clown trigger 50/50 is he ends up being a model citizen or a murderer when he matures. I hate to break it to you but the picasso also has a slight chance of turning bad when he matures. Many fish, especially aggressive natured fish, don't show their true nature until they mature. The picasso usually around 5", they are slow growers and the longer it the tank the better. A 220g is a good tank size for a mature picasso, but it is on the smaller side for a mature clown trigger. In all honesty when these fish mature they do better in a tank with equally aggressive mates, and a lightly stocked. There is also a risk if you introduce a clown trigger too small to defend himself, the picasso will immediately kill him.

Got it - I do not want to disturb the hierarchy in tank ... do not want ich or bullying ...

Would you recommend me adding 1 male and 3 female group of Bimaculatus Anthias?
