I am looking for suggestions on active reef fish. Currently, I have 1 Perc, 1 Sailfin Tang, 1 Foxface, 1 marine Catfish and 1 Lunar Wrasse. The tang and foxface have bursts of activity but spend a lot of time in the rock. The clown is always out and the cat and wrasse are rock dwellers as well. I am looking for active daytime swimmers for my 120 gallon reef setup.
