I guess coming from the world of african cichlids Raf & I know that when dealing with aggressive fish overcrowding works like a charm. This tank has been up for 5 years. With massive amounts of filtration the tank can handle it... the only problem I foresee is the fish outgrowing the tank (unicorn, I am watching you). We have plans to give them at the very least 400 gallons with as much length as possible. We have witnessed far too many cases with large fish in small tanks, it just breaks my heart. Actually quite a number of these fish have been rescues.
