Most of my aquariums are not perfect examples of biotope communities. Too many species and not enough tanks. This aquarium was set up to be the home of a colony of Xystichromis sp. ‘Dayglow’, one of the Lake Victoria basin species I want to maintain. I have one male and four females that I have grown up from 1/2″ fry. I started them in a 15-gallon tank until they were showing adult colors, then moved them to this 40-breeder. They have turned out to be very shy fish, and when they were in this tank alone I almost never saw them.
I like to use rainbow fish as dithers in peaceful to moderately aggressive cichlid tanks, especially when the water is harder and higher in pH. Since these Victorians are not too large or mean I chose to move my colony of Melanotaenia sexlineata ‘Tabibul’ in with them. This is a beautiful medium-size rainbow that is becoming more common. The work perfectly as dithers adn now the cichlids stay out front all the time. Hopefully they will spawn soon so I can grow this colony (five fish is too few!).
