Cichlids - Central American

A massive, apex predator from Central America known for its striking jaguar-like pattern and extreme aggression. Jaguars are highly intelligent, wet-pet fish but require enormous aquariums and heavy filtration. They will consume any fish that fits in their mouth and aggressively rearrange their environment.

Jaguar Cichlid Care Guide Summary

The Jaguar Cichlid, scientifically known as Parachromis managuensis, belongs to the Cichlids - Central American family group. Adults reach a maximum size of approximately 40 cm and have a fusiform body shape with a moderate growth rate. Classified as highly aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a extreme level of biological waste.

To thrive, the Jaguar Cichlid requires a freshwater only aquarium with a minimum volume of 680 litres and a tank length of at least 180 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 78.5 and a general hardness of 1020 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Jaguar Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Male (Standard Adult), Female, and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Jaguar Cichlid Habitat Setup

When setting up an aquarium for the Jaguar Cichlid, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Jaguar Cichlid Compatibility Notes

Classified as highly aggressive, the Jaguar Cichlid is best housed alone, as they do not tolerate others of their kind in confined spaces. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, conspecific aggression can be intense, especially in smaller tanks, and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Pterophyllum scalare

Cichlids - South American
15 cm Semi-Aggressive

The most iconic South American Cichlid, known for its distinct arrowhead shape and majestic fins. While domestic strains are hardy, they remain cichlids: they are semi-aggressive predators that will eat any fish small enough to fit in their mouths (like Neon Tetras). They form loose shoals as juveniles but pair off and become territorial as they mature. Height is more important than length for this species.

Red Devil Cichlid

Amphilophus labiatus

Cichlids - Central American
35 cm Highly Aggressive

A massive, extremely aggressive Central American cichlid. Aptly named, the Red Devil is highly intelligent, interactive, and famous for 'glass-banging' at their owners. They are powerful diggers that will uproot plants and rearrange decor. Because of their sheer aggression and jaw strength, they are almost exclusively kept as 'wet pets' in solitary setups.

Firemouth Cichlid

Thorichthys meeki

Cichlids - Central American
15 cm Semi-Aggressive

A popular Central American cichlid famous for the bright red coloration on its throat and belly, which it flares to intimidate rivals. They are earth-eaters, constantly sifting sand for food. While territorial, especially during breeding, they are relatively peaceful for a cichlid of their size compared to larger Central American counterparts.

Jack Dempsey

Rocio octofasciata

Cichlids - Central American
25 cm Aggressive

A robust, highly territorial Central American cichlid named after the aggressive 1920s boxer, William 'Jack' Dempsey. They exhibit beautiful iridescent blue, green, and gold spangling over a dark background. As aggressive diggers and plant destroyers, they require a tank with sturdy decor. They are best kept as a single wet pet or in a large tank with other similarly sized, robust Central American cichlids.

Hybrid cichlid (Amphilophus cross)

Cichlids - Central American

A man-made hybrid cichlid famous for its vibrant colors, extreme interactive personality, and the large nuchal hump (kok) on its head. They are incredibly aggressive 'wet pets' that will attack hands, tank mates, and equipment. They have a massive bioload, dig constantly, and must almost always be kept completely alone.

Convict Cichlid

Amatitlania nigrofasciata

Cichlids - Central American

One of the most ubiquitous and hardy cichlids in the hobby. Named for their black-and-white prison stripe pattern, Convicts are infamous for their intense aggression, especially when breeding (which they do readily). They are intelligent, wet pets that rearrange their tank décor constantly. Best kept in species-only tanks or with other robust Central American cichlids.
