Abalios Eartheater

Geophagus abalios is a medium-sized eartheater restricted to the middle Orinoco and its tributaries in Venezuela. It is a slender, elegant species with rows of iridescent blue-green spots on a silvery background, and breeding males take on an intense blue flush across the head and anterior body that makes them among the most colourful eartheaters in the hobby.

Like all Orinoco eartheaters, it benefits from soft, slightly acidic water and a deep fine-sand substrate. Groups of five or more reduce aggression and allow natural social structures to develop. This species is moderately active and appreciates open midwater swimming space combined with peripheral shelter.

Geophagus abalios is a biparental mouthbrooder with both parents sharing incubation duties. Captive breeding is achievable in well-maintained aquaria with consistent feeding and appropriate spawning triggers such as a slight temperature increase and water change.

Water: 25-29°C, pH 5.5-7.0, soft (1-8 dGH); clean, well-oxygenated water essential. Tank: Minimum 250L; fine sand substrate 8+ cm deep, open swimming zones, driftwood for shelter. Feeding: Quality sinking granules, frozen bloodworm, brine shrimp, daphnia; live foods enhance breeding colour. Breeding: Biparental mouthbrooder; blue coloration intensifies pre-spawn; flat sandy areas preferred. Compatibility: Semi-aggressive; best with other medium South American cichlids and robust schooling fish.
