达氏无须魮

Overview

Orange to red pectoral, pelvic, and anal fins distinguish Hypsibarbus wetmorei from yellow-finned H. vernayi. The body is robust, with reddish-brown coloration above. Confusion between these fishes is common in trade labeling.

Distribution & habitat

Its range includes the lower Mekong in Laos, Thailand, and Cambodia, several Thai drainages, and northern peninsular waters reaching Malaysia's Pahang River. Flowing habitats with substantial bank vegetation are preferred; reservoirs and similar standing waters are not characteristic habitat.

Seasonal movements occur, but the extent to which whole populations or separate local groups migrate remains uncertain.

Aquarium setup

A large footprint with clear swimming space is essential. Gravel, worn rocks, and branches can form a river-style setting. Effective space and water quality matter more than the decorative theme. Intolerance of organic waste is considered likely, so prioritize cleanliness and oxygenation.

Diet & feeding

Shrimp and snails are known wild foods and suggest browsing near the bed. Offer a varied captive menu of good flakes or granules, live or frozen additions, and vegetable matter. Match portions and particle sizes to the fish.

Behaviour & compatibility

With adequate room it is generally not aggressive, although crowding can cause problems. Small fishes may be swallowed, and slow or timid companions can be unsettled by constant movement and enthusiastic feeding. A group of six or more is preferable.

Sexual dimorphism

Mature females may be deeper and heavier than males and may also attain a larger size.

Notes

A yellow-finned fish labeled wetmorei is likely to be the similar vernayi. Their broad distributions overlap, so even wild shipments may contain both. Check identification before choosing breeding stock.
