Hello all, I have a feeling that you are all going to say I should leave him alone, but feel like I should ask anyway. I have a 13" male jag alone in my 125 gallon tank. Would you think it would be alright for me to add some more life to the tank? Or do you all think it would be Armageddon? I would buy other cichlids ranging from 8" - 12" and several dithers.
