Chromis conundrun

[Dickie]

Hey, I have blue bodied yellow tail chromis. One recently died. Now I have 2 in my nano. The question is should I replace this chromis with another one? I cant get another yellow tail because they are rare here. There is an abundance of green. Will a green chromis blend into the current chromis hierarchy? Will its different colour single it out and result in it being treated as another non chromis species?
I also have a clown fish and was considering just getting another clown to make a pair. Is this a reasonable course of action fishwise?

It all depends upon how big is your tank , its stability and how rigorous maintenance you do. For most nano tanks (<30G) , more than 3 fish is demands more care
