Corals fine as long as they dont bother each other , but some can overgrow others.

The tang and bleeny need to go . Chalk bass are cool fish and small. Just resaerch , there are very many smaller cool fish .
Or upgrade the tank as your eyes are bigger then your stomache. Remember that smaller tanks are harder to maintane then larger ones so whatching the water readings amount you feed and maint. are much more neseccery then a larger tank. And can go south real fast.
