I have a total of 3 different Centropyge angels in 2 of my reef tanks.
I do not have a fisheri, but I have a fisheri/resplendens hybrid & have not had any problems. I have multiple clams in both tanks, one of the tanks is an SPS tanks & the other is an LPS tank.

I have a 210 w/a male rhomboid, male lineatus, six line, melanurus, radiant wrasse, solorensis wrasse and 2 labouti wrasses and I have no problems at all.
