I have a 90g saltwater and I wanted to put the cast of finding Nemo in my tank for my neice and nephew. I have a yellow tang as well as 2 pecula clowns and two damsels. I have live rock in the tank and of course I want to add more. I kno that I won't be able to put coral or reef in it since I'll have a puffer fish but will they all fit in my tank?
