The lionfish is not with these guys its in a different tank.
still needs brackish conditions minimum they are a type of stonefish
My cichlid tank is : yellow lab, ob peacock, 2 parrots(hybrid), venustus, Butterfly and a featherfin catfish. There is nothing that can fit inside his lizard like mouth
good luck with this setup, , you have herbivores with omnivores and carnivors, the labs shouldn't have high protein diets as this will lead to things like malawi bloat which will kill them, aggression Will be a problem when they start to mature
All of these guys have been together in the same tank at the pet store for roughly 3 weeks.
that means Jack
