Hey i have 2 cichlid tanks a 30 gallon and a 70 gallon. I recently transfered one cichlid from my 30 to the 70 because he was being too aggressive he seemed fine for a few hours so i went to work. When i came home the other fish had almost completely bit all of his fins off and his body was a matted gray instead of gold. I put him in the 30 gallon and they picked on him too, so i bought a breeder and put him in the 30 gallon with the breeder and now he won't eat at all i've tried flakes shrimp and cichlid pellets he just doesn't seem to care. Is he going to die? i'm worried. 
to MFK!
