Flame angels are beautiful, just dont order them online, you never know what coloration your going to get, ill post you a pic in the morning of mine, all he does is swim around picking at algae or waiting for me to feed him.
And another idea, i know its probably going to be contested but i bought a pinktail trigger and he is probably the most interesting and coolest fish i have, he does not "nip" at anything in my tank, not even my inverts. He follows me around the tank and actually watches me, he yawns when hes tired, im not kidding..sweet fish.
