I am currently running a 55G setup, but I got a 150G. I am planning on setting up the 150 in the spring. will a blue tang be ok in the 150? Would I be able to add the tang to my 55 then move him to the 150 in the spring? I have 2 clowns and a purple firefish currently in the 55. I also have 2 emerald crabs and 3 very small pieces of coral.
