Bolivian Ram (Wild Form)

Mikrogeophagus altispinosus is the hardier, longer-lived cousin of the German blue ram, native to the Mamoré and Guaporé river basins in Bolivia and adjacent Brazil. Wild-form specimens display the species' true natural colouration: a warm gold-grey body with bold black dorsal markings, a bright red-orange tail margin, and scattered iridescent blue scales — all unsoftened by selective breeding.

Compared to M. ramirezi, the Bolivian ram tolerates cooler and harder water, making it a more forgiving choice for hobbyists who find the strict conditions of wild German blue rams challenging to maintain. It is still a cichlid requiring good water quality and a well-maintained tank, but its greater adaptability earns it beginner-friendly status among eartheater-related cichlids.

Breeding is straightforward: pairs form within groups, select flat stones or leaf litter as spawning sites, and guard eggs and fry with attentive biparental care. Wild-form individuals tend to show stronger parental instincts than commercially bred strains.

Water: 22-26°C, pH 6.0-7.5, soft to moderately hard (2-12 dGH); more adaptable than M. ramirezi. Tank: Minimum 80L for a pair; fine sand, flat stones for spawning, some plant cover for female refuge. Feeding: Quality small sinking pellets, frozen bloodworm, daphnia, Artemia; accepts a wide variety of foods. Breeding: Open substrate spawner; biparental care; easier to breed than M. ramirezi; fry are robust. Compatibility: Peaceful; excellent with medium tetras, corydoras, dwarf gouramis, and peaceful barbs.
