I currently have an established tank, 75 gallon mixed reef running one year now. Current residents are Scopas tang, One Spot Foxface, 3 Bangai Cardinals, 2 Firefish and the Yellow Candy Hogfish. Right now the tang, foxface and hogfish are best buds cruising and hanging together with zero aggression. The tang and foxface are small, I know one day they'll need an upgrade. My problem is I would like another couple fish. Some of the flasher and fairy wrasses are very attractive to me just don't want to affect the harmony in the tank. Any help is appreciated.
