Satanoperca leucosticta is native to rivers draining the Guiana Shield in Venezuela, Guyana, Suriname, and northern Brazil, including the Essequibo, Rupununi, and upper Branco River drainages. It inhabits slow-moving rivers and floodplain lakes with soft, acidic, tannin-stained water and sandy substrates interspersed with leaf litter and driftwood.
The White-spotted Eartheater is a visually elegant species, with a tawny-golden to olive-brown body covered in numerous bright blue-white iridescent spots across the flanks, cheeks, and dorsal fin. The eye is typically vivid red-orange in adults, which combined with the spotted patterning creates a striking appearance. Adults reach up to 20 cm and have the elongated snout characteristic of all Satanoperca species.
Like all Satanoperca, S. leucosticta is a highly specialized substrate sifter that continuously samples the sand for food items. In the wild, it is known as a delayed mouthbrooder: after spawning, the eggs are briefly incubated externally before being taken into the mouth of one or both parents. This behavior differs from obligate mouthbrooders and requires careful observation in the aquarium.
S. leucosticta is strictly peaceful and should only be housed with similarly gentle species. It will not compete aggressively for food or territory and can easily be outcompeted or bullied by more assertive tankmates.
