Winemilleri Eartheater (Orinoco)

Geophagus winemilleri inhabits the Orinoco tributaries and adjacent llanos drainages of Venezuela and Colombia. It is a more slender species than many Geophagus, with a somewhat elevated body depth and an attractive combination of red-orange and turquoise flank iridescence that develops fully in dominant males. It is a sand sifter and delayed mouthbrooder, forming loose social groups in the wild. In captivity it demands warmer and softer water than many congeners, reflecting its lowland blackwater habitat origins. Provide a generous fine-sand base, subdued lighting, and tannin-staining from driftwood or dried leaves to replicate natural conditions. Keep in groups of at least five individuals for confident behaviour and social dynamics.

Water: Soft; pH 5.5–6.8, temperature 25–29 °C, tannin-stained preferred. Tank: 250 L+; fine sand, driftwood, leaf litter. Feeding: Quality sinking pellets, frozen bloodworm, artemia, and cyclops. Breeding: Delayed mouthbrooder; loose group spawning. Compatibility: Peaceful with large, non-aggressive tetras and catfish.
