An obligate dweller of swiftly-flowing streams and headwaters containing clear, oxygen-saturated water. It often inhabits riffles and runs and is likely to show a preference for shallower zones.

Substrates are generally composed of gravel, rocks, boulders or bedrock carpeted with a rich biofilm formed by algae and other micro-organisms.

Juveniles are often found in slower-moving stretches with gravel substrate and submerged tree roots. In both cases patches of aquatic plants are only occasionally present but riparian vegetation is usually well-developed.

At the type locality of Homaloptera batek (Tan, 2009)[5] H. stephensoni was collected from a foothill stream running swiftly over a rocky/gravel substrate with clear water of pH 6.4.

It was observed only in the fastest-flowing riffles and other fish species included Garra borneensis, Paracrossocheilus vittata, Rasbora elegans, Homaloptera orthogoniata, Nemacheilus spiniferus plus unidentified species of Hypergastromyzon, Gastromyzon and Glyptothorax.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Aquarium size

An aquarium with base dimensions of 60 ∗ 30 cm or equivalent is required for long-term maintenance.

Maintenance

Most importantly the water must be clean and well-oxygenated so we suggest the use of an over-sized filter as a minimum requirement. Turnover should ideally be…

Diet

Homalopteroides spp. are specialised micropredators feeding on small crustaceans, insect larvae and other invertebrates. In captivity some sinking dried foods …

Behaviour and compatibility

Not an aggressive fish although its particular requirements limit the choice of suitable tankmates. Species inhabiting similar environments include Barilius, D…

Sexual dimorphism

Sexually mature females should be a little larger and fuller-bodied than males.

Reproduction

Presumably a seasonal spawner in nature but nothing has been recorded in aquaria.

Notes

This species is poorly-known in the aquarium hobby and may never have been exported for the ornamental trade. It can be told apart from congeners by the follow…
