I currently have a 120g (w/40g sump) stocked with a 6" one spot foxface, a 5" blue tang, two blue streak cleaner wrasse. They have been in the tank since January. I want to add some (3 or 4) disbar or randall anthias, a pearlscale and puntado butterflyfish, and a melanurus wrasse. My question is--Will the tang be problematic since it has been in the tank for so long? Should I move him out until the anthias, and others have settled in ? Is my plan to add anthias, then butterflies, then melanurus correct ? Would a fairy wrasse or two, be compatible in this tank with the melanurus?
