I'm setting up a 125 with peaceful fish. I've already got a pair of angels and a keyhole cichlid living in a 55 community with silver hatchets, black neons and a whole pile of cory cats. All of them wil be moving to the 125 once it's planted & cycled. I'd like to add a few more fish, so I was thinking another keyhole and a couple of festivums. I know they get big enough to eat my tetras, so I plan to start out with a half-dozen juvies and return any showing signs of maleness to my LFS. What concerns me is how they'll get along with the angels. Anyone with experience on the matter?
