This South American Cichlid was named after legendary heavyweight: Jack Dempsey, although usually smaller than the average adult Oscar fish (8 in – 20 cm)this beautiful cichlid is considered by almost everyone the perfect match for our bully pet: The Red Oscar. Do to its aggressive behavior Oscars soon will learn no to mess with “Jack”.
It’s not a good idea to have a couple of Dempseys unless you have a 6 feet long aquarium, the will become extremely territorial when breeding and will kill anything that does not stay outside their limits.
The female will choose a flat surface and clean it before laying her eggs, another favorite spot will be a large clay flowerpot .
The female will tend her babies while dad keeps intruders a safe distance from the developing eggs. The fry hatch in three days at 82 degrees Fahrenheit and are fully mobile four days later. Offer them newly hatched brine shrimp or finely powdered prepared foods for their initial meal. If fed several times daily and kept under a regime of frequent partial water changes, the hardy young grow rapidly.
Because Dempsey parents are as prolific as they are diligent, few aquarists have the space to rear an entire brood of fry to independence. To avoid overcrowding and all the problems that go with it, emulate natural predation by siphoning out 50 to 75 percent of the wrigglers for use as live food, and allow the parents to concentrate on caring for the remaining fry.
