The Yellow-Finned Hillstream Loach is a compact freshwater fish adapted to fast-moving, highly oxygenated water. Its flattened body, gripping fins, dark markings, and yellow fin accents make it an excellent addition to mature river-style aquariums. It spends much of its time grazing on biofilm and searching rock surfaces for small foods.
Key benefits:
Distinctive Coloration: Yellow fin markings contrast against the fish’s darker patterned body.
Natural Grazing Behavior: Feeds on biofilm, soft algae, and microorganisms growing on mature aquarium surfaces.
Peaceful Temperament: Works well with small, nonaggressive fish that prefer cooler, oxygen-rich water.
Specifications:
Scientific Name: Gastromyzon viriosus
Care Level: Moderate
Temperament: Peaceful
Adult Size: Approximately 2 inches
Minimum Tank Size: 20 gallons
Temperature: 68 to 75°F
pH Range: 6.0 to 7.5
Diet: Omnivore and biofilm grazer
Placement: Bottom and rock surfaces
Water Flow: High
Oxygen Requirement: High
Suggested use: Keep in a mature aquarium with strong circulation, high dissolved oxygen, smooth stones, and established biofilm. Supplement grazing with sinking foods, algae-based wafers, frozen foods, and small protein-rich foods.
