we originally had 2 green terrors and 2 oscars in the tank but then the terrors started ripping the oscars up and we removed the terrors when we started to notice that the oscars were all torn up so we removed them and they have been out of the tank for about 2 months and the 1 oscar died a few weeks after we removed them but the other oscar hasnt really recovered at all he still has gashing wounds all over his body and u can see his gills cause he is so badly cut up and he also keeps getting little circular holes in his tail that seem to eat there way out and his lip is kinda crooked i have no idea what to do at all and its really just confused me if u could give me any advice id greatly appreciate it...
i need help cause i dont know how much longer he is gonna last in that tank
