i have a snakehead (Channa Asiatica) around 3 inches long. he's currently not eating the food i'm giving him. he's been like this since yesterday. how much longer can he last without food?

Hey.
As I don't know the context, and am still learning myself, I can only speculate, so take it with a grain of salt please.
My channa is a little bigger than yours, and when I was going to take him home I was told he'd been fed two days prior, as it's best they aren't moved on a full stomach.
Was also told to not panic if he didn't eat, that he'd he'd be ok for about a week with no food as long as everything else about him seemed healthy.
He didn't eat for almost a full week.
Eventually I went and bought some live food to sort of jump-start him, showed him the bag and he seemed eager to eat.
But if I'd just left him alone, eventually he would have eaten pellets too. He does now.
If you can test your water, or take some in a bottle to a pet store, they should be able to help you do so. Always good to know for context.
Have you made any recent changes in the aquarium or around it that may have stressed your Channa out? Changed or modified your filter? Had drastic temperature changes?
They're very clever and attuned fish, so small things may be imposing to them. If there are high levels of nh4 or n02 in the tank and you need to change the water, do so.
Avoid putting your Channa in another tank while you change the water.
Use water that's the same temperature as your tank, always preferable to let it "age" in buckets overnight. Treat the water with aquatan or other product that preps your water and makes it safe, bacteria and your recommended/previous same dose of salt.
If your water is fine and everything else works, try to leave the tank and fish alone and don't change things or fuss too much.
Don't put food in unless they seem interested.. Sorry this was long, best of luck

Please have your water tested.

What are you offering? How big? We need context

I’ve never kept snakeheads but in general fish can go awhile without food. Obviously smaller fish can’t go as long as large fish. Give it time 1-3 days is nothing to panic about. You should buy a test kit though, they’re good to have, even just test strips will help you.

?? The guy was last seen July 5th. By now it would have either started to eat or have been dead by now

Very true

Do snakeheads need oxygen?

Air-breathing It can survive outside of water for up to four days. However, snakeheads can also use their gills to respire underwater, which they often do in the winter months. In summer, and in warmer conditions—which necessitates more oxygen—the fish solely breathes air though its suprabranchial organ.

What is the lifespan of a snakehead?

The protection allows more young to survive, increasing the number of these fish — including in areas where they are invasive. Northern snakeheads have an average lifespan of 10 years but have been documented living as long as 15 years.

Can snakehead live without air pump?

Because snakeheads are obligate air-breathers, they can live in poorly-oxygenated stagnant water. Out of water, they can survive for up to four days.

What is the biggest snakehead ever caught?

Malaysian angler Faizal Zainal potentially broke the All-Tackle World Record for giant snakehead (Channa micropeltes) with this massive 13.6-kilogram (30-pound) fish that he caught-and-released on February 28, 2018 while fishing outside of Rawang, Malaysia.
