Discus becomes sexually mature in about 2-3years. They will breed in the smae tank as where it is kept, they should never be transported to a special breeding tank. After the female is pregnant, the pair will separate and became quite agressive chasing other fish to corners. The eggs are laid on either rocks or plants and the young will hatch in about 50 hrs. The parents play a major role because they chew the membrane off the eggs for the fry to get out. The fry are protected by both parents and will swim by themselves in 2-3 days. The young have a typical elongated fish shape, but soon become more rounded. They grow rather rapidly and by three months they are the typical Discus shape. The juvenile coloration changes to the definitive pattern after eight to nine months. it should be noted that Discus frequently eat their own eggs.
