Gastromyzon stellatus

Care: Inhabit fast flowing streams over boulders. Aquarium must duplicate these conditions as fish have very high oxygen requirements.

With all Gastromyzon species, care is broadly the same. All need excellent water-flow and aeration, numerous rocky hiding places and smooth pebbles and boulders to graze over. Lighting should be bright to encourage algal growth in the aquarium. Plants are not necessary as the fish do not normally encounter them in the wild, but they will help with water-quality. Suitable plants for high-flow environments are Anubias and Microsoreum. These will grow on rockwork or driftwood.

Gastromyzon stellatus, undersideThis species seems to have great variability in the spot patterning. Various individuals have denser patterns and some lack the joined dots which often form "dashes" in the pattern.
