As one of the natural carnivores, wild betta fish like eating insects and insect larvae, which are high in protein. Some betta fish are greedy, they eat a lot of food because wild betta fish have to compete for food, or they will be starving. For the betta fish kept in your small aquarium, you can feed them with these foods.
Fish FlakesFish flakes are full of fillers, which will make your fish feel full more easily while taking in fewer nutrients. And it will also pollute the water in your aquarium, which will affect the water quality. The fish flakes are not recommended on most occasions, but if there is no choice, you can feed your betta fish with them.

A betta fish has a small stomach that is about the size of its eye, so remember to soak the pellets for a while because they will expand roughly twice their size in water. If you don’t soak them before feeding them to your betta fish, the pellets will expand in your betta fish’s body, causing constipation and even death.
Freeze-Dried FoodsFreeze-dried foods are easy to get and have a long shelf life, you don’t have to worry that the foods will be expired before your betta eat them up. Compared with live foods, freeze-dried foods contain no parasites that will bring disease to your fish.

Including insects larvae, brine shrimp, mysis shrimp, blood worms, and algae. These foods should be stored in your freezer, then thaw them before feeding to your betta. They may be more expensive than other foods, but they are high in the protein and nutrients your betta fish need, and they can be stored for a long time. what’s more, although the larvae, shrimp, and worms are dead at the time of feeding, they do provide an environment that is similar to the wild.
The only drawback is that it may cost a little time to thaw.
As we mentioned before, wild betta fish like eating insects and insects larvae, so you can feed them with some live foods, such as insects larvae, blood worms, brine shrimp, and so on. Don’t forget to rinse them thoroughly before feeding them to your fish because there will be many bacteria on their bodies.

How to prevent overeating
Wild betta fish have to fight for food, so when they are kept in a fish tank with no competitors, they will eat as much as they can, which will cause overeating. Sometimes overeating can be very dangerous for betta fish. It will lead to digestive stress, a severe gastrointestinal condition, bloating, swim bladder problems. and obesity.
To prevent your fish from overeating, the first thing you should know is how to tell whether they are full or not. Generally, betta’s feeding time lasts for about 2 minutes since their digestive tracts are very small. So after feeding for 2 minutes, you can see if there is a slight bulge in their belly, which is a sign that they are full.
Once you have known the amount of food that will make your betta fish full, feed them with the roughly same amount of food each time.
Then you need to clean the excess food in the fish tank. If you don’t clean out the excess food, they will continue to eat until the food has been eaten up. Cleaning out the excess food can also avoid water pollution, which will harm betta fish’s health. You can use a water changer or a filter to remove the uneaten food in your aquarium.
If your betta fish have overeaten, you can try to make them move around to digest the food they eat and let them feel more comfortable.
