捷豹慈鲷
Parachromis managuensis is a cichlid native to Nicaragua in Central America: the scientific name means "from Managua" (as in Nicaragua's capital city). It is a food fish and is also found in the aquarium trade where it is variously known as: the jaguar cichlid, managuense cichlid or managua cichlid, guapote tigre, Aztec cichlid, spotted guapote and jaguar guapote. It grows to 32.5–35 cm
The species is a carnivorous, highly predatory fish. Their diet consists mainly of small fish and macroinvertebrates. They prefer turbid, eutrophic lakes, often found in warm water depleted of oxygen. Their native substrate is one of mud-bottoms, but can also be found in other ponds and springs with sandy bottoms covered in plant debris. They natively live in lakes of approximately 5 m (16 ft) in a tropical climate and prefer water with a 7.0–8.7 pH, a water hardness of 10–15 dGH, and a temperature range of 25 to 36 °C.The Parachromis managuensis (commonly known as the jaguar cichlid) is the most commonly traded species of its genus and is greatly valued among the aquarium trade. As with all members of the genus, the jaguar cichlid is a large, aggressive and territorial member of the cichlidae. All members of the Parachromis are visually alike, and can only be identified by minor differences in apperiance. The Jaguar cichlid is a large, robust cichlid, displaying a shade of yellow/bronze throughout the body. This yellow colouration is then scattered with vivid black spots which are seen all along the flanks and gill plates. A series of several large black dots then run horizontally along the lateral line area.The fins are often a dark to black colouration, especially when in spawning colouration.
The female is similarly colored, but generally smaller than the male. The female will also lack the elongated extensions to the dorsal fins.
The Parachromis managuensis is capable of reaching 13" in length with the female slightly smaller than the male, reaching lengths of about 9–10". It is highly advisable that a breeding pair of jaguar cichlids, or any other member of the Parachromis, are kept singularly,with the exception of very large aquaria, as a breeding pair will become hyper-aggressive, and pose great danger to any other fish in the tank..The aquarium should be large (400 l +) for a breeding pair of jaguar cichlids. As with all members of its genus, These fish are large and heavily built cichlids who are aggressive and highly territorial. Decor should be kept to a minimum in such an aquarium and sand or fine gravel should be used as the main substrate. Many pieces of flat slate or rock should also be included for the purpose of spawning.
