Channa andrao
A small snakehead from northeastern India with a dark body, iridescent blue fins and no pelvic fins. Only about 14 cm, the male mouthbroods, and it needs a cooler winter season.
Channa andrao is a small snakehead described in 2013. Endemic to the Brahmaputra basin in northeastern India, it is formally known only from a swamp in Jalpaiguri district, West Bengal. FishBase gives a maximum of 14.2 cm TL. It was in the hobby before description under names such as 'Lal Cheng', 'Assam' and 'blue bleheri', and has also been sold as other species such as C. bleheri or C. stewartii. It lacks pelvic fins and is most often confused with the rainbow snakehead (C. bleheri), from which it differs in lacking orange spots on the tail, having two rather than five dark bands on the pectoral fin, and being a mouthbrooder rather than guarding floating eggs. Its habitat is influenced by Himalayan snowmelt and cools in winter, so captive fish need defined winter and summer seasons. In Japan it is sold by specialist shops, including captive-bred fish.

14〜28℃
Carnivore (frozen bloodworm, prawn, fish pieces)
14-28°C, pH 6.0-8.0, 2-20 dGH (Seriously Fish). Do not keep it at a constant temperature; provide a cooler winter, during which it needs little food.
Seriously Fish suggests an 80 x 30 cm footprint. Keep lighting dim with floating plants, cover and leaf litter. A notorious escape artist, it needs a gap-free lid with an air layer above the water.
Best kept in a species tank, though peaceful non-territorial companions may work. Mature fish become aggressive to each other, females often more so.
Carnivorous: give juveniles bloodworm, small earthworms and chopped prawn, and adults fish strips, prawns and mussels. Do not rely on dried foods.
A paternal mouthbrooder bred regularly in captivity. Let a pair form from 6-8 young fish. The female feeds free-swimming fry with unfertilised eggs, and brood care lasts several weeks.
It may be sold under other species' names, so check for orange spots on the tail and the number of dark bands on the pectoral fin. It weakens without access to air at the surface.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Blue rainbow snakehead is 14〜28℃. Avoid sudden temperature changes and maintain a stable environment.
Blue rainbow snakehead typically reaches Up to 14.2 cm TL (FishBase) as an adult. Size may vary depending on care conditions and individual genetics.
