Buying snakehead fish9/10/2023 Snakeheads are also capable of some powerful bursts of acceleration and apt to knock things around in the tank or stir up substrate. Surface cover, created by floating plants, is also recommended. Ample hiding spaces in the form of driftwood and submerged vegetation should therefore be provided. They spend a lot of time hovering in midwater or resting on the bottom within cover as ambush predators. They are not active swimmers and, when not feeding, tend to move only when surfacing for air. Snakeheads are fairly undemanding as regards tank décor. Many snakeheads come from habitats where water is soft (to 8 GH) and slightly acidic to neutral (pH 5.0 to 7.0), and these values represent a suitable guide to successful maintenance. While some snakeheads can tolerate a wide range of water conditions - and studies have shown that the Dwarf, Spotted and Chevron can survive for at least 72 hours in pH levels from 4.3 to 9.4 - many fare poorly when water conditions are allowed to deteriorate or undergo rapid changes, as in a massive water change. There’s a common misconception that air-breathing fish live in stagnant, relatively foul water in the wild and that clean water conditions are therefore not necessary in the aquarium. Many fish with a similar biology, such as walking catfishes and even the pirarucu (Arapaima), will drown if they do not surface. If you find the concept of a drowning fish strange, remember that snakeheads are not the only obligatory air breathers. Snakeheads are in fact obligatory air breathers and must have air lest they drown. They are primarily able to do so because of their paired suprabranchial chambers which are lined with respiratory epithelia (skin modified to absorb atmospheric oxygen) enabling them to use atmospheric oxygen as sub-adults and adults. One unusual feature is the snakeheads' tolerance of low oxygen levels. 'Kerala five stripe' - have already reached the aquarium trade. There are two genera (Channa, Parachanna) containing 34 species (31 Channa and three Parachanna), although the diversity is much greater and several undescribed species, particularly from India - for example, Channa sp. These fish are naturally distributed from south-eastern Iran and eastern Afghanistan eastwards to China, northwards to Siberia and southwards to Java, and from the White Nile westwards to the Senegal and Chad river drainages and southwards to the Congo river drainage in Africa. Snakeheads are members of the family Channidae, a group of perciform (perch-like) fishes whose affinities are unknown, although recent studies on the molecular phylogeny of bony fishes consider snakeheads as most closely related to the labyrinth fishes (anabantoids) and the synbranchiform eels, which include the spiny eels. They earn their name because their flattened shape and the scales on their heads are reminiscent of the large epidermal scales on snakes. They have been thrust into the limelight because of the picture painted of them as an aquatic invasive species but, whatever your opinion, snakeheads make great aquarium fish if given proper care. The long-term impact they would have on a smaller body of water is unknown, which is why biologists urge all of us to not introduce them to new water.Any discussion of predatory oddball fish for the aquarium will invariably feature a snakehead or two. It’s a large and diverse waterway, which is a far cry from the small lakes and streams where snakeheads have recently been found. The Potomac River has had a snakehead population for over 20 years, and according to, Virginia DWR biologist, John Odenkirk, snakeheads haven’t negatively affected game fish populations. While snakeheads can survive out of water for short periods of time, they cannot walk on land. And no, they aren’t walking on land to new bodies of water. But, people continue to move these fish into new waters despite the urging of biologists. Bucket biologists can face a $2,500 fine and up to one year in jail for illegally stocking snakeheads in Virginia. Introducing a non-native species is never a good thing for a natural ecosystem, and wildlife agencies have tough penalties for anyone caught spreading snakeheads to new water. Snakeheads are a species native to east-Asia, but have been introduced to countries around the world through the pet trade and illegal aquaculture.
