I have 2 oscars in a 75, They have been in there together for almost 6 months and been fine. Just recently they have began, what seems to me courting each other, They quiver at each other and occasionally lock lips. But today I got back from class to find both of their mouths pretty tore up and missing some scales on their side. They wont leave each others side but still seem pretty tore up. Should I leave them together or separate? Should I be worried or just let it play out.
