What Neon Borneo Sucker look like

Gastromyzon lepidogaster, commonly known as the Neon Borneo Sucker, exhibits a laterally compressed, fusiform body shape that is characteristic of hillstream loaches. Adults typically reach a maximum size of 3 to 4 inches (7.5 to 10 cm), with some individuals reported up to 10 cm under optimal conditions. The species displays sexual dimorphism, with males generally being slightly smaller and exhibiting more vibrant coloration during breeding periods. The body is pale with a pattern of darker spots, providing effective camouflage against the rocky substrates of its natural habitat. A notable feature is the fused pelvic fins forming a suction disc, which allows for adherence to fast-flowing surfaces, an adaptation crucial for survival in turbulent waters. Additionally, the presence of a lateral line system aids in detecting water movements, enhancing its ability to navigate and forage in its environment.

Behavior & temperament

The Neon Borneo Sucker is primarily a benthic species, often found clinging to rocks and substrates in fast-flowing streams and rivers. It exhibits a social structure that can be described as loosely communal; while not an obligate schooler, it is often observed in small groups, particularly during feeding. The species is generally peaceful but can display territorial behavior during breeding, where males may engage in displays to attract females. Breeding occurs through egg scattering, with females laying adhesive eggs on surfaces, which are then fertilized by males. The temperament of this species is typically calm, although it may exhibit shyness in the presence of larger or more aggressive tank mates.

Diet & feeding

In the wild, the Neon Borneo Sucker primarily feeds on algae and biofilm, scraping these from rocks and surfaces in its fast-flowing habitat. In captivity, it requires a diet rich in spirulina and other algae-based foods, supplemented with blanched vegetables and high-quality sinking pellets to ensure proper nutrition.
