Jurupari Eartheater

The Jurupari Eartheater, scientifically known as Satanoperca jurupari, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 25 cm and have a compressed body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the bottom zone of the aquarium and produces a high level of biological waste.

To thrive, the Jurupari Eartheater requires a freshwater only aquarium with a minimum volume of 280 litres and a tank length of at least 120 cm. Water temperature should be maintained between 26°C and 30°C, with a pH range of 5.5–7.5 and a general hardness of 1–10 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Jurupari Eartheater is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard (Adult) 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.

When setting up an aquarium for the Jurupari Eartheater, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise 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.

Classified as mostly peaceful, the Jurupari Eartheater is a social species that requires the company of its own kind to thrive. When choosing tankmates, boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Jurupari Eartheater is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 5. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Jurupari Eartheater like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.
