Channa bleheri blue - Tropical Fish for Sale UK

Blue is a rare currency in freshwater fish, and the blue form of Channa bleheri spends it generously. This dwarf snakehead variant wears vivid blue colouring over the species’ compact frame — around 10cm at adulthood — and brings the same fascinating predatory presence that makes Channa so absorbing to keep. Care is rated Moderate: achievable for an attentive keeper, unforgiving of guesswork, and centred on getting temperature and stocking right.

Like its rainbow relative, the blue bleheri runs cooler than typical tropicals at 20–26°C, in soft water of pH 6.0–7.5 and 2–12 dGH. A 60-litre aquarium is the minimum, which makes this one of the most space-accessible snakeheads we list. It is a carnivore occupying the middle of the water column, and a semi-aggressive one: the standard approach is to keep it singly, or with very carefully chosen, similarly sized peaceful tankmates in a large, heavily planted tank. Most community fish are simply not appropriate. Any companion must be too large to eat and entirely uninterested in nipping fins; exclude small fish, shrimp and other small invertebrates, overly aggressive or highly territorial species, and fast-feeding hyperactive fish that would beat it to every meal.

The 60-litre figure deserves context: it is the floor for a single fish, and the heavily planted, larger layout described above is the price of any company at all. Many keepers happily run the singleton option — one blue snakehead, one well-furnished tank, no compromises — and with hardness anywhere in the 2–12 dGH band and a relaxed pH window, the water itself is the easy part. The hard part is restraint at stocking time. Lifespan runs to roughly eight years, with territoriality rising around breeding.

Considering this fish?

Settle the stocking question before purchase: a singleton setup is simple to run, while a mixed tank needs the space, planting and tankmate screening described above from the very start.
