Yeah I guess he is a mutt, and no the one side never produces any color. I got him quarter sized in July and he is about 1 1/2 inches body size. I can't wait until he gets full grown!!! He is with some barbs, neons, a peacock eel, glass catfish, a small quarter sized angelfish and a kribensis cichlids and 3 otos, so a community tank. My brothers dumped in all the barbs, catfish, eel etc. and I am going to get a new tank for some of them hopefully! They also put a KOI fish in there and we will build a pond for him this spring
