Otopharynx walteri

Otopharynx walteri is a rarely exported deep-water species found along rocky slopes in Lake Malawi, typically collected from depths below 20 m. Males display a clean blue-silver body with orange-tipped anal, dorsal, and pelvic fins — a delicate and attractive color combination that stands out subtly against the bolder colors of tankmates in a mixed Hap display.

Due to its deep-water origin, this species appreciates cooler water temperatures toward the lower end of the Malawi range and benefits from excellent oxygenation replicating the well-oxygenated deep-water conditions of the lake. It is an understated but refined choice for the collector who appreciates less-common, rarer Malawi Haps.

Maternal mouthbrooder. Females are grey-silver and difficult to distinguish from other Otopharynx females. Males should be kept one per tank to avoid aggressive territorial disputes. A peaceful and elegant addition to any large Malawi Hap community.

Water: pH 7.6–8.8, 24–27°C, GH 10–20, KH 10–18; pristine conditions with excellent oxygenation; avoid temperatures above 27°C. Tank: 250 L minimum; rocky structure with caves; some sandy areas; moderate lighting preferred. Feeding: Omnivore pellets, frozen mysis, small krill, spirulina; feed twice daily in small portions. Breeding: Maternal mouthbrooder; females hold ~3 weeks; separate brooding female for best fry survival. Compatibility: Compatible with Peacocks, Copadichromis, and peaceful Haps; avoid aggressive tankmates.
