The 55 gal. that I had before moving, I started with damsels, and then added one perc clown, then another perc clown, then a yellow tang, then a blue hippo tang. They all worked well together and I never had any problems, I think that was because I did it slow and added the most hearty first. Also I added my corals kind of sparaticly (didn't know if that mattered or not?) This 110 gal. tank that I am working on is a little more of a task, and just because I have more space, I don't want to get impatient and add too much too fast once I get her up and running.
