Native range
Captive domestic form; parent species occurs in South-east Asian hill streams and running waters.
Natural habitat
Base husbandry on Pearl Danio ecology: clear running streams with open surface/midwater space, plants at the margins and good oxygenation.
Diet & feeding
Omnivore/insectivore; parent species feeds heavily on terrestrial insects and zooplankton. Use varied quality prepared and frozen/live foods.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
