i have it in a mix tank...as for peacocks i had one female sunshine, a male regal, a male jacobfribergi, and this one. now this is the last one of my peacocks. the female had a spawn and was kill off by my other africans in the tank(about 20 at the time). my heater was set to high from winter and it got to 87f and killed the jacobfribergi, and my regal got sepsice i beleve. i was going for an all male tank and some females got in, both africans and the sunshine peacock. is there a diff. between the ruby red and orange shoulder?
