wow! awesome Thanks! I would love to pair the flame angel it is def one of my favorite fishAll Pomacanthidae are born female. Until they grow larger and either establish a pair, or become dominant, they stay female. Easiest way to pair angels, especially Centropyge, is to find an (obviously) smaller one than what you have. Both species are commonly seen in the trade so this wouldn't be an issue. You will want to QT well (as with all fish) and ensure they're acclimated to captivity and accepting the foods that you feed. There will undoubtably be some chasing and dominance establishing rituals , but if healthy and fat the new addition can take it and they'll likely pair off. Whenever I add new fish, or particularly trying to pair fish, I use an acclimation box in my main tank. This process is referred to as "socially acclimating" and allows the current residents view the new addition, but can't come into direct contact with them - good for both!
