We have a 125 gallon S. African Cichlids tank. There is a Puffer, 2 Clown Loaches, 3 Tiger Barbs, & a Plecostomus in it. The Chichlids leave all the other fish alone but they fight over territory for themselves, they need lots of hiding places. We have 2 double filter Wisper filters hanging on the back, & a canister filter below. They are a little dirty with debris on the bottom, have to completely vaccum the gravel & change 20% H20 every month. Our biggest problem is breeding. Every maintenance day we have to give babies away, but they are very colorful. Sometimes me & the wife will just sit there & watch fish TV.
