Frozen Food

Betta fishes are carnivores, which means they need to eat as much protein as possible. And this is where frozen foods come into play. Frozen foods for betta fishes are live insects or microorganisms that are frozen to expand their shelf life.

For this food, feed your betta fish with frozen fruit flies, mosquito larvae, bloodworms, or brine shrimps. But keep in mind that you should only use frozen food that came from trusted stores, and not the ones you may have caught outside your backyard.

This is because getting frozen food from random sources may have already contained some parasites and diseases with them depending on where they came from.


Pellets are one of the most common food types for fishes. There are myriads of fish pellets available in the market today. And they are also easily accessible, unlike frozen foods.

Keep in mind that there are different types of pellets depending on the brand. So opt for one that contains fewer fillers to prevent your betta fish from bloating.


Just like pellets, there are also plenty of fish flakes available in local stores or online. But beware! You should only feed your betta fish with flakes specifically for them.

Avoid feeding them with flakes for tropical fish as it may contain less protein and other essential nutrients your betta fish needs.


Freeze-dried food is just live insects that have undergone a freeze-drying process to keep them stable and last for longer.

But, they contain more fillers to keep their structure and form. Only feed your betta fish with freeze-dried food in moderation. Doing it frequently can lead to bloating and stomach issues for your betta fish.

Blanched Peas

If your betta fish is suffering from mild constipation, blanched peas can help ease it out. Blanched peas are high in fiber making it effective to help stomach problems your betta fish might be experiencing.

But, only feed your betta fish with blanched fish when needed. Treat blanched peas as an emergency food only and not something that you need to feed them regularly.

Live blood worms

Bloodworms (also known as Glycera) are mostly in ponds. They are small and are also a favorite among betta fishes too. Betta fishes treat bloodworms as if something that you can find in an eat-all-you-can buffet.

Best Food For Betta Fish

Live mosquito larvae

Mosquito larvae are prominent in a betta fishes’ natural habitat. But keep in mind that mosquito larvae are only active during warmer climates. You will have a hard time sourcing for one during winter.

Live brine shrimp

Brine shrimp are very tiny and can only grow up to 1-centimeter maximum. They call brine shrimp the ultimate “energy food” for betta fish as they are high in protein, fiber, vitamins, amino acids, and all other essential nutrients.

Live mysis shrimp

Mysis shrimp is your best choice if your betta fish is a picky eater. Their exoskeleton is rich in fiber, and it also contains twice the vitamins and minerals that in brine shrimp.

How Much Should I Feed My Betta Fish?

In feeding your betta fish, keep in mind its portion size. But, this will also depend on the type of food you will feed your betta fish.

Ideally, its foods’ portion size should only be equal to 5% of the body size of a betta fish. Food cleanup is also important. You should remove any excess food that sunk on the bottom of the tank as soon as possible.

Betta fish can thrive in a healthy environment. Keeping excess food for long can cloud the water and may hurt your betta fish. This can lead to further health complications or death.
