General Notes:

Neonoemacheilus labeosus is a little known loach from Asia where it lives in fast flowing streams which are very well oxygenated. In captivity good water quality with a high oxygen content is essential. Good filtration and regular water changes are necessary to achieve this.
Their aquarium should have a fine sandy substrate with some smooth water worn stones and bogwood for hiding in.
Neonoemacheilus labeosus comes from exposed shallow streams and so their aquarium should be brightly lit in order to replicate this.


Small aquatic inverts make up the bulk of the natural diet. In the aquarium live or frozen blood worms, daphnia, brine shrimps, cyclops along with suitably sized sinking pellets will ensure a good diet.




There are no external differences between the sexes.


No reports of aquarium breeding.
