Hey there I have a multiple tanks. at home a 7''+ emperor angel full adult colors and at my office I have a Koran angel 3'' changing. my Emperor at home as started a habit of nipping at my LPS softies, and even my RBA's. now my question is can I put my emperor in my tank at my office with my Koran angel or will my emperor kill the koran? the tank and current stocking: 75 gallon with 1 WP-40 (3200pgh), DC-6000 return pump (1500gph), Reef Octopus Diablo DCS 250 In-Sump Protein Skimmer rated up to (500 gallon systems), and 150lbs of live rock. the stocking is 3'' Koran, 4'' humu trigger, 3'' yellow tang, (2) 2.5'' sabea clowns, (4) 1.5" green chromis. the tank it HEAVLY fed daily to keep aggression down (hence the super sized skimmer to deal with the extra waste and foods) . the fish do not fight at all. I do a 25 gallon water change every two weeks.
