I've been racking my brain trying to figure out a cichlid/center piece that could go with these guys. Something with a level of aggression like a convict or above would surely kill them but watching the way they act I'm sure they'd make life really miserable for something more peaceful like an angel, a firemouth or even a parrot.Rosies are tough as nails and move really well
I'm impressed with how quickly they made themselves at home. The second I put them in the tank they were grazing all over the place. The next day they were spawning.
