hey everyone, i want to add a copper band butterfly to my 60 gal reef tank, the ONLY issue is an aggressive flame angel who doesn't take very kindly to them or tangs (thus i don't have either of those fish). the flame is perfectly fine with the wrasses, chromis, gobbies, and clowns that i have. any tips on how to add a CBB without the flame scaring him to death (literally, the one that i tried adding was too afraid to come out of the corner to eat) would be greatly appreciated. thanks!
