About

Otocinclus tapirape hails from the Tapirapé River, a tributary of the Araguaia in Mato Grosso state, central Brazil. Like many recently described Otocinclus species, it remains understudied in both scientific and hobbyist literature. Its morphology is consistent with the genus: small, armoured, fusiform body with a ventral adhesive disc and terminal, transverse mouth equipped for rasping biofilm from hard surfaces.

The Tapirapé drainage is characterised by clear, warm, soft to moderately hard water flowing through tropical gallery forests and grasslands. The region experiences distinct wet and dry seasons, creating temporal variation in water level and temperature that these fish are naturally accustomed to. O. tapirape likely forages in groups over submerged wood, rocks, and aquatic vegetation in shallow stream margins.

For the aquarist, O. tapirape represents an opportunity to keep a genuinely rare, locality-specific species while still benefiting from the practical algae-cleaning function that makes Otocinclus so popular. Its care is standard for the genus, and experienced otocinclus keepers will find its maintenance familiar. The challenge lies in sourcing the species, as it is only sporadically available from specialist importers.

Care Guide

Water: Soft to moderately hard at pH 6.0–7.0 and 22–27°C; high water quality maintained by regular partial changes. Tank: 40 litres minimum with plants, wood, and leaf litter reflecting Tapirapé river ecology. Feeding: Biofilm primary; supplement with courgette, cucumber, and algae wafers; established tanks with natural algae are ideal. Breeding: Not documented in captivity. Compatibility: Peaceful with all small community fish and invertebrates.
