Jurupari Eartheater Care Guide - Aquarium Setup, Diet & Breeding

The Jurupari Eartheater is a graceful, deep-bodied cichlid with a gently sloping forehead, elongated fins and a subdued silver, olive and brown colouration. Depending on mood and conditions, darker vertical markings can appear along the body, while the fins may show delicate blue, gold or reddish highlights. The eyes are often marked by a dark stripe or patch that contributes to its expressive appearance.

This species earns its common name from its distinctive feeding behaviour. It takes mouthfuls of sand, sifts out small edible organisms and organic material, then expels the cleaned substrate through the gill openings. Watching a group work methodically across the bottom is one of the most appealing aspects of keeping these cichlids.

In nature, Jurupari Eartheaters inhabit quiet backwaters, sandy margins and leaf-strewn stretches of rainforest rivers. Their natural surroundings can change significantly between seasons, with flooded forest and submerged vegetation providing additional feeding areas and shelter.

Although they are cichlids, they are generally less aggressive than many similarly sized members of the family. They are social, observant fish that establish a hierarchy within a group and become especially interesting when pairs form and display parental behaviour.

Satanoperca jurupari is native to slow-moving rivers, tributaries and floodplain waters of northern South America, particularly across parts of the Amazon and Guiana Shield drainage systems. Its range includes Brazil and neighbouring countries such as Guyana and Suriname.

A group should have at least 300 litres, with a larger aquarium preferable as the fish mature. A footprint of approximately 120 × 50 cm is a sensible minimum, with additional length and floor area particularly valuable for a group. Use fine, soft sand that can be safely sifted through the mouth and avoid sharp gravel. Arrange smooth stones, bogwood, roots and sturdy plants around the edges while leaving broad open areas for foraging. Moderate water movement, efficient filtration and shaded areas help recreate the calm, structured environment of their natural rivers.

Males can reach around 25 cm (10 inches) in length, while females are usually smaller at approximately 18–22 cm (7–8.5 inches). Aquarium specimens are often somewhat smaller than the largest wild adults.

Their natural diet consists of small aquatic invertebrates, insect larvae, crustaceans, worms, plant matter and detritus collected from the substrate. Offer a varied diet of quality sinking cichlid pellets or granules, frozen or live foods such as bloodworm, brine shrimp, daphnia and mysis, along with occasional vegetable-based foods. Feed small portions regularly so every fish can forage naturally without leaving excessive food in the sand.

Jurupari Eartheaters can live with similarly sized, peaceful South American fish that appreciate warm, soft to moderately hard water. Suitable companions may include larger peaceful tetras, peaceful barbs, medium-sized peaceful loricariid catfish, robust Corydoras species and other calm eartheaters. Avoid very small fish that may be swallowed, highly aggressive cichlids and fin-nipping species. They should not be mixed with territorial or predatory tankmates that are likely to intimidate them, and their social group requires substantial aquarium space.

Jurupari Eartheaters are biparental mouthbrooders. A compatible pair usually lays eggs on a clean, solid surface such as a stone or piece of wood, after which both parents may take turns carrying the eggs and larvae in their mouths. Provide excellent water quality, gentle circulation and plenty of open floor space, and avoid disturbing the pair during spawning. Raising a group of young fish together is generally the most reliable way to allow pairs to form naturally.

Sexual differences are subtle outside the breeding period. Mature males are generally larger and may develop somewhat longer dorsal and anal fins, while females tend to have a rounder body, particularly when carrying eggs. Reliable sexing is difficult until a pair forms or the fish are examined during spawning.
