My cichlids are only 2-2.5 inches I'm hoping to be getting an upgrade before they get bigger than that. My pleco is bigger than them. I've never seen them bother my molly or my tetras, They used to bother my platy and gourami so I seperated them. Theres 2 albinos and they follow eachother everywhere. I guess when I see them actually bother my other fish, then I'll worry. But thanks for the warning. If anything, I'd get rid of the cichilds just because its 2 of them vs. 7 of the others.
