I am wanting to put one of my raised babies into my reef to establish another breeding pair. There is a adult bangaii in there already. Along with a 4" leopard wrasse, a true perc, yellow tang, and algae blenny. How large should I let the baby get before considering putting him in there. He looks to be about an inch counting his tail fins. He is not being very cooperative in taking frozen food which is why I want him in the reef so he can see others feeding on it. What do you guys think?
