Gastromyzon zebrinus

Gastromyzon zebrinus is a Bornean hillstream loach belonging to the family Gastromyzontidae, recognized for its flattened body, broad paired fins, and distinctive zebra-like markings that help it blend into rocky, fast-flowing stream habitats. Its ability to cling to stones in strong current, graze on biofilm and fine algae, and move with a unique gliding motion gives it a highly specialized charm that appeals to aquarists interested in rheophilic freshwater species. When understanding Gastromyzon zebrinus in aquarium care, it is important to provide clean, cool to moderately warm water with strong flow, high dissolved oxygen, smooth stones, and mature surfaces rich in biofilm, as these conditions help support its natural grazing behavior, healthy coloration, and long-term vitality.
