Mapiritensis Eartheater

Satanoperca mapiritensis is a seldom-encountered eartheater from the Venezuelan Llanos and Orinoco tributary systems. It is a more slender species than its congeners, with a subtler patterning of iridescent scales and a small but distinct lateral spot. Its rarity in the trade gives it significant collector value, and specimens in prime condition are breathtaking.

As a blackwater Satanoperca, this species demands clean, soft, acidic water and is unforgiving of lapses in water quality. A spacious tank with deep fine sand, tannin-producing botanicals, and efficient filtration provides the ideal environment. It is best kept in small groups to promote natural social behaviour.

Satanoperca mapiritensis is believed to be a biparental mouthbrooder following the standard Satanoperca breeding pattern. Breeding in captivity is rare and represents a significant achievement. Dedicated keepers who can source and maintain this species are encouraged to document and share captive breeding results.

Water: 25-29°C, pH 5.0-6.5, very soft (0-4 dGH); blackwater conditions with tannins strongly recommended. Tank: Minimum 250L; fine sand, heavy botanical additions, driftwood; excellent biological filtration essential. Feeding: Small sinking pellets, live and frozen invertebrates, daphnia, bloodworm; variety is key. Breeding: Presumed biparental mouthbrooder; rarely bred in captivity; pristine conditions required. Compatibility: Peaceful; best with small to medium tetras, pencilfish, and non-aggressive catfish.
