I am to the point where I would like to add one more fish and be done, but I don't know what I should get. I like gobies but I don't like finding fish dried to my floor. I like angels but am worried about coral nippers. What would you add? I have a pair of Ocellaris clowns, a one spot foxface, a blue hippo tang, and a powder blue tang. The tank is a 5 foot 120. The powder blue was the last addition about 1.5 months ago.
