Suggestions for 180g peaceful FOWLR

[cowfish]

Right now, in the 180, I've got a tassled filefish, orange spot filefish, carberryi anthia, camelback cowfish (tetrasoma gibbosus), a CBB and 2 skunk cleaner shrimp.

I plan on adding another 2-3 carberryi anthias.

Any fish or invert suggestions? I'm trying to avoid anything with the potential for heavy aggression or predation so no scorpions, large wrasses, etc.

Thanks.

I'll suggest the fish I suggest for everyone, orchid dottyback. Non-territorial, small, nice color, fun to watch, and even better in harems!

Purple is good! Is there an easy way to differentiate males from females?

I have read that it's all in the shape of the tail, but I don't know if that is true or not.
