Alternative names

Native range
Rakhine Yoma region of western Myanmar, including the Thandwe drainage.
Natural habitat
Clear to moderately flowing streams, drainage channels and seasonal waters over rock, gravel and sand; good oxygenation and open swimming space are important.
Diet & feeding
Small aquatic and terrestrial invertebrates plus plant material; use varied quality flakes or small pellets with frozen/live foods.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Females are deeper-bodied and fuller when mature; males are slimmer and generally more strongly coloured.
Breeding
Egg-scattering cyprinid with no parental care. Adults readily eat exposed eggs and fry, so use mesh, mops or dense plants for controlled breeding.
