Yeah, i want to but i got some coral eating critters in there right now. Chocolate Chip isn't reef safe and not sure about the flame, singapore or tang though. The cc hasn't tried eating my anenomes, yet.
I actually have 3 angels in a 125 they been together for 1.5 years. I have 1 koran, 1 flame, and 1 bi-color. Its all how you raise them
Actually I think it is introducing them all at the same time. About 6 months ago I got cocky and bought a coral beauty. The flame almost killed it in 1/2 of a day; I returned it. The Koran is dominate but does not constantly harrass the others; the two dwarfs are buddies I have never seen them go after each other.
