ive got this tank dems are 91x31x33. In it know are a powder blue tang, a naso tang, a chocolate mimic yellow tang, a kole tang, an atlantic blue tang, a gold bar maroon clown, 2 Longfin Bannerfish, 3 tazmanian devil damsels, a lime green wrasse, a foxface, a picasso trigger, a niger trigger, a porcupine puffer, and a garibaldi. so if im counting right thais 17 fish the largest is maybe pushing 8 inches most in the 3-6 inch range. im just wondering if there is anything else i could add to this tank?
