AKA Gastromyzon species SK02
Common name: Hillstream loach
Distribution: South Kalimantan, Indonesia
Sexual Dimorphism: Females
probably plumper all over than males.
Maximum size: 2 inches (5 cm)
Similar to: Other Gastromyzon species.
Care: Inhabit fast flowing streams over sand,
gravel and rocks. Aquarium must duplicate these conditions as fish have very
high oxygen requirements.
See: Hillstream Loaches: Specialists at Life in the Fast Lane for more detailed explanation.
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
Feeding: Good quality flake, sinking pellets, algae wafers, thawed frozen Bloodworm, Mysis Shrimp, blanched Spinach, Kale, natural algae an advantage.
Water parameters: pH:7.0-8.0 Hardness: Medium Max dh: 12
Temperature: 75.2ºF to
bred in aquaria.
This fish was collected by Hendra Budianto in the wild and designated SK02 for reference purposes.
It is notable in mature specimens for having a pronounced secondary
rostrum (nose area) that overhangs the lower and is noticeably longer at the
outside edges, giving a concave appearance when viewed from above.
The habitat was a hillstream about 8-12 M wide, up to about 80 cm deep.
The water was very clear and the current strong.
Temp. 26 C, pH 7.8, TDS 054 ppm.
Substrate of sand mixed with gravel and rocks.
