well what i would do is get a male and They reach maturity at around 6", which is approximately a year to a year and a half old. Eggs are generally laid on a smooth piece of rock or a small pit dug into the substrate. Unlike most SA cichlids, G. Surinamensis are partial mouthbrooders, either parent will take the fertilised eggs in their mouth and hold them until hatching which occurs around 3 days later. After hatching, the fry will stay close to their parents, taking shelter in their mouths if danger threatens. As with most cichlids, the parents will be very protective while caring for a brood, and this is the only time that any serious aggression will be shown. They breed more readily in softer water with a neutral ph, and many people have had success using one of the "blackwater" water conditioners that are available, as they simulate the fishes natural habitat.
