I wanted to try a lot of small fish in my 125 Like cardinals, anthias, and chromis. Problem is it can get pretty expensive with 10-15 anthias. I was thinking a cheaper alternative would be a tank full of blue damsels. Has anyone ever tried this?

Problem with that is most likely they will kill each other and if that doesnt happen it will be real boring after awhile and then try adding another type of fish
