Flame Angel advice?

hi

Hi,
My local lps says some angels like to nip at coral, the coral beauty seem to be more docile than some of the others.
They tell me only one angel to a tank or there will be problems.
Same with tangs, I guess if you buy one the same time as the other and maybe they were tank mates at the store it would be better. My tang was chasing the coral beauty around for about 24 hours.
I am amazed how territorial some fish are,
My two burgandy clown stay in the left corner of the tank behind a large rock and if any one comes near its gonna get uggly.
I move some coral around and was bit about four times by the burgandy clowns, The four clarki clown all hide in their anemome when I work in the tank.
I found a nice roya gamma and he was threatoning everyone in the tank with a open mouth head shake that lasted about 24 hours he had one tooth like a moray eel , i didn't know they had teeth that large it looks like a wolf fish with its mouth open..

If you want to add another flame, make it as small as posible!!!!! Your current one will, or sould have already turned into a male. When I say small I mean like 1 inch or less. Then they should pair up, and youll have the joy of having a pair of flames. You never know they mite even mate...

 

Are flame angels A-Sexual as juveniles? I didnt know that.
