I have a relatively small pond (~500 gallons) in my backyard and keep cichlids in it from about sometime in april till october or november (texas climate). Last year I kept geo winemilleri and tapajos, and various peacocks and haps that I was trying to grow out over the summer. Only the african cichlids tend to be visible and they move so fast much of the time they can be hard to view for long. This year I am keeping otapa swords and CA cichlids such as T. Maculipinnis, T Pasionis, and soon C. Nanoluteus. They are doing great outdoors and the T Mac's spawned just a few weeks after moving them outdoors. They are visible when directly in the sun, otherwise they are hard to follow.
