Lemon Fin Barb - Hypsibarbus wetmorei Fish Profile & Care Guide

Lemon Fin Barbs (Hypsibarbus wetmorei) exhibit striking and dynamic characteristics. They typically display non-aggressive behaviour unless confined in a limited space. However, they may consume smaller fish and assert dominance over slower or timid fish due to their constant activity and robust feeding habits. These Barbs are a schooling species and ideally should be kept in groups comprising at least six or more individuals. This species holds a favourable reputation as a dither species among enthusiasts who keep predatory fish and Cichlids, thanks to their resilience, active nature, and general compatibility with tankmates of similar size.

When it comes to setting up an environment for Lemon Fin Barbs, the emphasis lies less on decorative elements and more on maintaining optimal water quality and providing ample open swimming space. Nonetheless, for those interested in creating a long-term habitat, an aquarium designed to mimic a flowing river proves aesthetically pleasing. This setup should include a substrate composed of a mix of rocks and gravel in various sizes, along with smooth boulders and driftwood branches. Similar to other species originating from running waters, these Barbs are likely to be intolerant of organic waste and necessitate pristine water conditions with a high level of dissolved oxygen to flourish.

The visual characteristics of Lemon Fin Barbs are noteworthy, with an upper body sporting a reddish-brown hue complemented by shiny metallic diamond-shaped scales. Furthermore, their bodies develop a distinct yellowish sheen, while their pectoral, pelvic, and anal fins exhibit a pleasing yellowish-orange colouration.

Natural Habitat

Lemon Fin Barbs, indigenous to Southeast Asia, inhabit the lower Mekong Basin in regions encompassing Laos, Thailand, and Cambodia. They are also found in the Tapi, Chao Phraya, and Mae Klong systems in Thailand, as well as various smaller watersheds in southern Thailand and northern Peninsular Malaysia, extending as far south as the Pahang River.

These Barbs thrive in environments characterized by moderately flowing waters adorned with abundant riparian vegetation. They are notably absent from standing bodies of water, such as reservoirs and other man-made impoundments. These Barbs are typically encountered at midwater to lower depths within medium-sized forest streams. While they are not known for migratory behaviour, they may exhibit upstream movement during periods of elevated water levels.

Despite being locally common and categorized as a species of Least Concern, Lemon Fin Barbs face significant threats, particularly within certain segments of their habitat range. These threats include overfishing, the construction of dams, and the presence of pollution, all of which contribute to their vulnerability.

Breeding

Achieving successful breeding of Lemon Fin Barbs within a home aquarium is likely to pose a considerable challenge, primarily due to their substantial size. Regrettably, there is currently no documented record of successful breeding endeavours with these fish.

Diet & Feeding

Within the confines of an aquarium, Lemon Fin Barbs display a straightforward approach to feeding. However, it is advisable to provide them with a diverse diet, encompassing live and frozen offerings such as daphnia, bloodworm, and brine shrimp. Additionally, high-quality dried flakes and granules should be included in their diet, supplemented generously with ample vegetable matter.
