I would like to add a copperband butterfly to my reef to control aptasia. I have read that they are pretty hard to keep and considered to be a delicate fish. Below is my current inhabitants, that are all well established. Do you guys think I could successfully add one to my system?? 1 yellow tang 1 mandarin dragnet 1 magenta dottyback 1 blue sapphire damsel 2 clowns 3 lyretail anthias 1 cleaner shrimp It is a 100 gallon mixed reef, thanks in advance for your input.
