Please anybody correct if I'm totally wrong about this but I'm pretty sure that they can be with other fish that are too big for him to eat and peaceful to where it won't bother him. The Barbeled leaf's mouth is huge compared to its body size so I would suggest fish that are just as big as him but being this is a 30 gallon your tank is going to get full very fast. He needs a heavily planted tank so that he can feel secure hiding with its natural camouflage and so that he can stalk his prey as he is a predator.
