Channa Andrao (Channa Andrao)

This dwarf snakehead is native to the Brahmaputra river basin in Assam, north-eastern India, where it inhabits shallow, densely vegetated waters that undergo strong seasonal change, drying out significantly during winter.

It's one of the smallest snakehead species in the hobby, with a charcoal body set off by deep blue, iridescent fin edges and a subtle red wash through the flanks, making it a popular choice for hobbyists wanting a colourful, more manageable Channa.

Unlike many larger snakeheads, Channa andrao pairs bond reliably in captivity and can often be kept together as adults. They also benefit from a distinct seasonal temperature drop over winter, reflecting the conditions of their natural habitat, and tend to show their best colour at a slightly lower pH.

We recommend a dimly lit tank with dense hardscape, driftwood caves and leaf litter, a gap at the water's surface for air access, and a heavy, tight-fitting lid, as this species is a notorious escape artist.

Care

• Fish size: 10-12cm

• Tank size: 60 litres minimum for a single fish, 100 litres for a bonded pair

• Temperature: 22-26℃, with a cooler winter period recommended

• pH: 6.0-7.0

• Filtration: gentle to moderate flow, but strong biological filtration due to bio-load

• Diet: carnivorous — bloodworm, small shrimp, earthworm, small live or frozen fish
