My Tank has different types of tetras, lampeyes, Buenas Aires, Emperor, and diamond and glowlight tetras there's also Swordtails and cory and b-nose cats and rams. I agree that Kribs can be territorial and protective. I think that they took off one of my rams tails this happened before and it caused one of my old rams to die. So should I justl leave until they get bigger and then move them to another tank? My Kribs are impossible to catch in such a big tank.
