Different fish have different feeding requirements, but on average most fish can eat twice a day, small doses each feeding. A different food for morning and night is also recommended but not required. Such as flake in the morning and a frozen shrimp in the evening.

you feed them every other day to them.

You won't need to feed fish as often because it keeps them "full" longer.
One or twice per day.

What to feed a fish is not dependant on whether it was wild caught or captive raised, you feed a fish based on whether it is a predator, omnivore or herbivore. Though wild fish will more often need fresh foods, instead of prepared. At least when first aquired.
At least once or twice a day.
You have to feed a Berta fish 3 pellets in 1 day because I have a betta fish and it eats fine
You should feed your betta fish flakes once or twice a day, giving them only as much as they can eat in about 2-3 minutes. Overfeeding can lead to health issues for your fish.
