Not yet but working at it. My 125 gallon is a Discus and other species tank, Sterbai Cories, Boesemani Rainbow, Rams and L046 Zebras. The 90 gallon is Rams, Boesemani Rainbow, Bushy Nose, Sterbai Cories and Tiger Barbs no Discus. I am working with a new 75 gallon setup that is almost ready for grow out and as I increase my discus population I might shuffle things around. My zebra L046's are almost ready for their own tank as a species only and they don't need a very large tank since the don't travel far from their caves and the stay small. So for now my fry is the only discus only tanks.
