Parhomaloptera microstoma Profile

[Martin Thoene]

Scientific Name: Parhomaloptera microstomwa (Boulenger, 1899)

Common name: None.

Synonyms: Homaloptera microstoma

Distribution: Borneo, Indonesia

Sexual Dimorphism: Females probably plumper all over than males.

Maximum size: 3.5 inches (8.8 cm)

Similar to: Homaloptera species.

Care: Inhabit fast flowing streams in fastest riffles. Aquarium must duplicate these conditions as fish have very high oxygen requirements.

See: Hillstream Loaches: The Specialists at Life in the Fast Lane for more detailed explanation.

With all Homaloptera and similar 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.

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:

Temperature: 68ºF to 75ºF (20-23.8°C)

Breeding: Not bred in aquaria.

Notes: Parhomaloptera microstoma is a possible import as a contaminant with other Indonesian species, but it is unlikely that it has specifically been exported.
