how big is your tank? for your fish's sake i hope its huge. or 5 of them will likely be killed if you are succesfull in getting a pair
Easy to breed once you have a pair, which is somewhat difficult. Sexes are somewhat difficult to tell - generally, the males have more blue reflective scales than the females, who tend to have a deeper reddish hue with a wider girth. However, this is not always the case. Place one mature male with a number of mature females and watch for a pair bond to form, then remove the others as they will be killed if forced in close proximity to the eggs. The female will lay several hundred eggs on a flat surface - usually a dugout in the back of the aquarium, although you can provide flat rocks to encourage them. The eggs will hatch in a few days and the fry will be guarded in typical cichlid fashion. They can reproduce approximately every 3 weeks once they get going.
generally speaking the males are much more colorful than the females.
