Named for Ambastai (or Ambastus in Latin), a river in Ptolemy’s (identified as the Mekong).
Black Lined Loaches come from shallow rivers and streams with a good flow
and they require clean well aerated water if they are to thrive. Use soft
sand as a substrate in order to avoid damage to their barbels. They should be kept in large groups because they form
strong hierarchies, if too few are kept it will result in bullying, A group
of five to ten individuals should get along without serious bullying once a
pecking order has been established.
Aquatic insect and larvae form the bulk of their natural diet. In captivity they are relatively unfussy and will accept live or frozen blood worms, daphnia, cyclops, brine shrimps. They will also take suitably sized pellets and flake food along with a range of fresh greens such as cooked peas without their skin and cucumber. Black lined loach will also eat any snails in the aquarium and they may nibble plants.
Generally peaceful but needs to be part of a group. Black lined loaches may nip fish which have long flowing fins.
Adult males are smaller, more slender and more have slightly stronger colours than adult females.
Black lined loaches have not been bred under normal aquarium conditions.
Ambastaia nigrolineata is listed as being vulnerable by the ICUN Red List
