More anthias doesn't always mean more fun. When you get them into a school they form a well defined pecking order. This usually involves having the smallest one being beaten on until it dies, then the next and so on. Oh, and the dominant female can change to male, which causes the dominant male to kill that one too. Big happy families... Dispars are less prone to this but it does happen. Unless you have a really big tank, I'd stick with the pair and get a compatible but different species. I keep 3 different species of anthias together without issue.
