Assuming this isn't a wind-up, and honestly, your message is written just like one...
The Red Snakehead is Channa micropeltes. This species is amongst the worst aquarium fish in the world. The main problem is that they will, repeat will, get to about a metre in length. They *do not* grow to the size of their tank. This is why they're good food fish: you can pack 'em into the pond, and they'll still grow, assuming diet and water quality allow.
Snakeheads are generally not difficult to feed, but they don't have much interest in dried foods. You need to be offering juveniles things like earthworms and river shrimps, and adults should be weaned onto beefheart, frozen seafood, and small frozen fish such as lancefish. As always with predatory fish, you need to choose food carefully to avoid fat and especially thiaminase (which is in things like shrimps and mussels, and long term, causes problems).
They are red only when small. Adults are more mottled blue-grey. It is considered a destructive and invasive pest fish in some parts of the world, and consequently banned from the aquarium trade, e.g., in California, Florida.
When I was a teenager these fish were rather widely sold. Thankfully, they are now rarely seen in British aquarium shops.
