I have a 60 gallon tank currently stocked with a 4 inch female jd. Anyway I have tried several different possible tank mates with my jd and none have worked so far. They include a blood parrot, a fire mouth, and an Oscar. I now have a male blue gene jd, a female jd roughly the same size as mine, ad a Salvini all available for me to try. Would any of these be good to try with my aggressive jd or should I just keep her all alone. I like her and don't really want to get rid of her.
