Jauruense Twig Catfish

Farlowella jauruensis is endemic to the Jaurú River system in Mato Grosso, western Brazil, a region that drains into the Paraguay River and the Pantanal wetlands. It is one of the least frequently exported members of the genus and remains a prized species among Loricariidae enthusiasts. Its exceptionally long snout distinguishes it from most other Farlowella species and likely reflects adaptation to extracting food from narrow crevices in woody debris.

The Jaurú River is characterised by warm, moderately soft water with seasonal flooding that creates extensive flooded forest habitat. In the aquarium, Farlowella jauruensis thrives best when given a heavily decorated tank with large pieces of driftwood, leaf litter, and marginal vegetation to simulate its natural environment.

Due to its rarity in the hobby, little has been documented about its captive breeding behaviour, though it presumably follows the standard Farlowella pattern of egg-guarding on flat surfaces. Keepers should expect a settling-in period during which the fish may be shy and reluctant to feed.

Water: 24–28°C, pH 6.0–7.0, soft (GH 2–10); Pantanal-style warm conditions preferred. Tank: 100 L minimum; large driftwood pieces; leaf litter substrate; subdued lighting. Feeding: Algae wafers, blanched courgette, spirulina; allow biofilm to establish before introduction. Breeding: Poorly documented in captivity; follow standard Farlowella protocols. Compatibility: Peaceful only; avoid all boisterous or large tankmates.
