The brilliance of the juveniles is reduced. Their background color is tan or dull gray and the flex is a dull turquoise color.
Growing at Home
The Jack Dempsey shows a typical way of spawning in the open. The temperature for spawning suggested is about 78o. Spawning at temperatures lower than this is impossible. In case the female is not ready to spawn, the male deals harshly on her and may not even hesitate to kill her. At the moment a couple is ready to spawn the remaining fish in the tank, is either destroyed or chased out. The Jack Dempsey is used to first cleanse the rock and then spawn over it. For this it needs a particular rock, without which it will not spawn. The size of the spawn is possibly 500 eggs, which get hatched within 3 days. Following hatching of the spawn, the couple shifts the fry to tiny holes that they dig in the gravel.
Identifying the Jack Dempsey female from the male is confusing. The female is smaller in size compared to the male and they are dull colored. The water quality suggested is neutral with hardness, ranging from soft to medium; the temperature suggested is 78 to 82 F and pH value 7.0. Jack Dempsey breed in the open, they require water that is properly oxygenated.
The size of the tank suggested for a single fish is not less than 50 gallons, However a, bigger tank is required for many. This Jack Dempsey requires enough space for moving and a very good filtration process. Equip the tank with sufficient plants between the wood and the rocks for camouflaging. A few floating plants like Sagittaria will be cherished. Also provide fine gravel at the bottom of the tank. While arranging the plants, display them around the inner walls of the tank, leaving a central portion free for them to swim. In order to prevent the roots from uprooting, pot them or keep floating plants.
Jack Dempsey adjusts to most of the temperature conditions; even then, if the water is warm, the fish becomes aggressive. For reducing this inclination, most of the aquarists retain the temperature to a maximum of 78oF (26oC)
This carnivorous Jack Dempsey consumes all frozen and prepared foods, which includes Tubifex, frozen and dried blood worms and ocean plankton, also live fish.
