Bahuaja Crossoloricaria

Crossoloricaria bahuaja is named for the Bahuaja-Sonene National Park river systems in the Madre de Dios region of southeastern Peru, a biodiversity hotspot draining into the upper Madeira. The genus Crossoloricaria is characterised by a notably wider, more depressed head than most slender Loricariid whiptails, giving these fish a slightly more robust appearance. This species is among the least exported Loricariids from Peru.

In the aquarium, Crossoloricaria bahuaja requires clean, soft water with moderate flow and a fine substrate. Its care parallels that of other large loricariid whiptails — good filtration, stable parameters, and a diet based on algae wafers and fresh vegetables with occasional protein supplementation. Given its rarity, any husbandry observations from keepers are of value to the hobby.

The species is presumed to be a crevice or shelter spawner based on related genera. Providing appropriate spawning sites such as wide flat tubes or rock caves of suitable dimensions is advisable for hobbyists wishing to attempt breeding.

Water: 22–27°C, pH 6.0–7.0, soft to moderate (GH 2–10); moderate flow. Tank: 120 L minimum; sand substrate; flat rock caves or wide tubes for shelter and spawning. Feeding: Algae wafers, spirulina, blanched vegetables, occasional frozen foods. Breeding: Presumed shelter spawner; limited captive data available. Compatibility: Peaceful; upper Madeira or general South American community.
