  • Reticulated Hillstream Loach (Sewellia lineolata)

    Reticulated Hillstream Loach (Sewellia lineolata)

    $16.99

    Probably the most beautifully marked of all the Asian hillstream loaches, the Reticulated Hillstream Loach or Reticulated Butterfly Sucker is found in fast-flowing, rocky streams and creeks in Central and Northern Vietnam. Like many of their close relatives, this species is perfectly adapted for life in fast moving waters, with their modified pectoral and anal fins forming something of a natural suction cup. This unique adaptation allows them to not only attach firmly to surfaces but also to move forward against strong current and climb up sheer rock faces and waterfalls. They will do best in an aquarium with slightly cooler, well-oxygenated water with moderate to strong current. They will readily feed on biofilms, algae, and certain prepared foods like Fluval Bug Bites Pleco Formula or Repashy Gel Diet. A social and outgoing species, they will thrive in groups of 5 or more and have been successfully bred in the aquarium.

  • Neon Borneo Sucker (Gastromyzon lepidogaster)

    Neon Borneo Sucker (Gastromyzon lepidogaster)

    $119.99

    The Neon Borneo Sucker (Gastromyzon lepidogaster) may be the most stunning loach from the “Borneo Sucker” complex. G. lepidogaster are unique in the fact that as they age, they change color. Young begin life as a small, nondescript, black hillstream loach. In sub-adulthood, they go through a dramatic color transformation, changing from black to bright-orange. When sexually mature, they change their color again, this time to a bright, reflective-green. Mature, older, adults can switch between their three color phases at will; or, choose an intermediate color between the two. Specimens that choose to wear a combination of the orange and green are sight to behold. The entire body of the fish has what almost appears as a “dusting” of iridophores: structural pigments that make them appear to “sparkle.” This is a truly “holographic” fish. As with all rheophillyne loaches, G. lepidogaster needs very clean (minimal TDS, no organic waste), slightly-acidic, highly-oxygenated, cool water (50F-80F; room temperature is fine).
