Reticulated Hillstream Loach (Sewellia lineolata)


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.
