I have a 29 gal reef setup and already have 2 dams 2 tom clowns and a diamond back gobie and i am wanting to add one more fish. First is that to many and if not could i get a suggestion on what fish to add.
I'd say that given the eventual size of the tomato clowns, their aggression level, and the fact you have two damsels, you are already maxed out at best. At worst, overcrowded a bit.
