Jaguar Cichlid (Parachromis managuensis) Care Guide
Parachromis managuensis is a large, highly predatory Central American cichlid requiring a very large tank and careful tankmate selection.
Compiled by Aquairi from published sources · Published · Updated
Overview
Parachromis managuensis, the jaguar cichlid, is a large, highly predatory cichlid from Central America with a leopard-like spotted pattern. It is a powerful, territorial fish that requires a very large aquarium and is generally housed only with conspecifics or comparably large, robust tankmates.
Taxonomy
- Family: Cichlidae
- Genus: Parachromis
- Scientific name: Parachromis managuensis
- Common synonyms: Cichlasoma managuense, Herichthys managuense, Nandopsis managuense
Habitat
Native to the Atlantic slope of Central America, from the Ulúa River in Honduras to the Matina River basin in Costa Rica. It prefers turbid, eutrophic lakes with mud bottoms and tolerates warm, oxygen-poor water.
Tank requirements
- Minimum tank volume: 600 L
- Temperature: 25-29 °C (77-84 °F)
- pH: 7.0-8.0
- GH: 8-18 °dGH
- Lifespan: 12-15 years
Diet
A highly predaceous carnivore. Adults feed mainly on small fishes, while juveniles take a variety of macroinvertebrates. FishBase reports a high trophic level of about 4.0.
Compatibility
An aggressive, territorial species. It is unsuitable for typical community setups and will prey on or harass smaller fish. Suitable companions are limited to other large, robust species such as large plecos, while most fish and smaller cichlids should be avoided.
Breeding
A substrate spawner that forms pairs and provides biparental care of eggs and fry, typical of the genus.
Conservation status
IUCN Red List: Least Concern (assessed 2020).
Jaguar Cichlid Breeding Guide
Overview
Parachromis managuensis is a large predatory cichlid whose natural range extends down the eastern side of Central America, from the River Ulua in Honduras through Nicaragua to the River Matina in Costa Rica (Seriously Fish). It is a biparental substrate spawner: a pair cleans a flat surface, spawns on it and then moves the hatchlings into pits dug in the substrate, guarding the brood together. The species can reach about 24 inches but is usually smaller in aquaria.
Sexing
Males grow larger than females, reaching a total length of 65 cm versus about 40 cm in females (Wikipedia). Males have pointed dorsal and anal fins and generally more colour, while females are smaller and more rounded and lack the elongated extensions to the dorsal fin. During spawning the fins of males often darken to a near-black coloration.
Breeding Setup
Because the species is large and aggressive, a spacious tank with a sand substrate and flat surfaces for egg deposition is required; Seriously Fish lists minimum aquarium dimensions of 120 x 45 x 37.5 cm (about 212 litres) for younger fish and much larger volumes for adults over 12 inches. Suitable water for the species is around 23-25 °C, pH 6-8 and hardness 6-18 °dH (Seriously Fish).
Spawning Behavior & Trigger
The parents clean a chosen surface and spawn there, after which the eggs and hatchlings are transferred to spawning pits dug into the substrate (Seriously Fish). Both parents tend the brood. The best way to obtain a compatible pair, as with most large Central American cichlids, is to grow several juveniles together and let a pair form.
Egg & Fry Care
Broods are very large: a single spawn from 12-inch parents can produce around 3000 fry (Seriously Fish). The parents provide care for up to about 6 weeks, by which point fry reach roughly 15-25 mm. Older fry must be removed at this stage, otherwise the parents will kill them while guarding a new batch.
Common Challenges
The extreme aggression of this species makes pairing difficult, and an incompatible partner may be injured or killed. The very large broods require substantial grow-out space and the timely separation of older fry before the next spawn.
