would a very aggressive jack dempsey be compatible with fishes such as a convict or a green terror? My J.D. is currently residing in a 20 gallon tank with no other fishes. He sadly killed my bicher and pleco, which totally sux. I do not want to risk another one of my fishes to die, so please reply and tell me as much as you can.
Quit being SOooo HARSH!!!!!!!!!!!!,
