I sold some fish out of my tank and just left my Aba Aba and Black wolf fish. Well it seems to upset the harmony and the black wolf bit about 2 inches off my aba's tail. Will it heal and grow back. I just added some salt.
It will grow back even if the bones were cut off. Mine was even worst than before when one of my bichirs accidentally mistook it as a food and grab and hold of the aba aba's tail and spin and cut it off. It grew back to normal.
