New Fish Tank Tips: Don’t follow the 1 inch of fish per 1 gallon of water rule. A better guide would probably be 1 inch of fish per 2 or 3 gallons of water. Use the future adult size of your fish when computing how many fish you can keep. Resist the temptation to overcrowd your tank. The more tropical fish you have the more often you will have to perform fish tank maintenance.

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 55–63 cm (22–25 in).
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 coloured, but generally smaller than the male. The female will also lack the long elonged extensions to the dorsal fins.
The Parachromis managuensis is capable of reaching 13″ (330 mm) in length with the female slight smaller than the male, reaching lengths of about 9–10″ (230–250 mm). It is highly advisable that a breeding pair of jaguar cichlids, or any other member of the Parachromis, are kept singularly, as a breeding pair will become too aggressive for any other fish to be added.
Breeding can be achieved with very little effort and no specific requirements are needed for such purposes. As long as water conditions are maintained at a desirable high quality, a breeding pair of jaguar cichlids will readily spawn. To enhance the likelihood of acquiring a breeding pair, purchase several healthy and active juveniles at a young age (between 6 and 10) and grow these specimens until sexual maturity. Generally, you should be left with a breeding pair or two. These fish will noticeably become more aggressive and territorial, Remove all other fish at this point and keep the newly formed breeding pair separate. When a breeding pair had been successfully established,The male will begin to court the female by displaying his erect finnage as he tries to impress her in an attempt for her to accept his mating invitation. The pair will begin to clean a flat surface if the female is responsive of the male’s previous courting behavior.The female with then lay approximately 1000–2000 orange coloured eggs which will then be fertilized by the male. The eggs will be ferociously guarded by both parents and a high degree of parental care is shown to the eggs and fry. When the eggs ‘hatch’ after approximately 5 to 7 days, the offspring (known as wrigglers at this stage in development) are defenseless and are unable to swim. They are often transported to pre dug pits by both parents, and are guarded. The fry will begin to swim in approximately 7 days and should be fed with baby brine shrimp or alike. If you would like to rear these fry, they should be removed at this point as they will later be consumed by both parents as the female becomes due to spawn once more. Feed the fry baby brine shrimp until the stage where they are large enough to consume blood worm, daphnia and other live foods. When purchasing fish in an attempt to acquire a breeding pair, try to buy fish from different sources. There is a high probability that when buying fish from the same source, Fish will be from the same parents (Siblings). This should be avoided, as breeding fish in this manner may form offspring with genetic disease usually associated with interbreeding. Also, buy fish of a similar size, the chances of acquiring a breeding pair with fish of a similar size is significant to that of attempting to breed fish of different age and size.
