A fighting fish is otherwise know as “Betta Fish”. A varied diet will maximize the health of your Siamese fighting fish.

You should offer high quality specialised Siamese fighting fish pellets/granules and supplement this with black worms, brine shrimp, frozen tubifex worms and daphnia.

Siamese fighting fish should be fed 1-2 times per day in very small amounts (2-3 pellets or pieces of other food). You should ensure all foods aside from pellets are broken into tiny pieces before feeding.

Can Betta Fish Eat Food Meant For Humans?

A very controversial topic amongst betta fish owners is whether their pets should be given human food. The answer is yes, but only occasionally.

You can serve your betta fish human food on occasions where you have run out of fish food or if you want to give your fish a little treat.

However, giving human food to a betta fish all the time is not good. Your betta fish will not be able to survive entirely on human food.

A betta fish cannot digest processed foods, and the preservatives can also make them sick. Betta fish are carnivores, which means that majority of their diet consists of meat-based meals.

Whatever human food you give to a betta fish, make sure it is only a supplement and not a replacement for an entire meal.

Just like any other animal, betta fish also prefer a little variation in their diet. When giving human food, make sure that you follow the same guidelines as you do for commercially-bought food.

The food must not contain any fillers, preservatives, chemicals, or additives. It must also fulfill the dietary requirements of your betta fish.

Some Human Foods You Can Feed a Betta Fish

Following are some human foods that you can feed your betta fish occasionally:

Boiled Peas

Remove the outer skin of the peas and boil them until they are mushy or cut up into very tiny pieces. Your betta fish will enjoy it!

Peas are an excellent source of fiber and can prevent constipation and bloating. Make sure you remove the shell and the skin before you give peas to your betta fish.


Lightly microwave or boil spinach leaves and cut them up into tiny pieces to feed your betta fish.

However, not all betta fish will like spinach. Try giving it to your betta fish and see if it enjoys it.

Sweet Corn

Sweet corn is an excellent treat for betta fish. Boil sweet corn kernels and cut or mash them up. Remember to remove the outer skin at all costs.

Even though delicious, a sweet corn kernel does not contain any nutrients, so make sure your betta fish gets its nutrients as well.


The best way to give cucumbers to a betta fish is to boil it until it is soft and cut it up into tiny pieces. Nibbling on cucumbers gives your betta fish a yummy treat and enables faster digestion.


Just like spinach, lettuce leaves are also beneficial for your betta fish. They contain a high amount of vitamins.

Just make sure that you do not give very large quantities of lettuce to your betta fish. Always cut and boil lettuce leaves before giving them to your fish.


Since betta fish are carnivores that live in the sea, they rely on other small fish for their diet. Therefore, betta fish will deficiently enjoy some seafood!

You can give your betta fish fresh pieces of shrimp, scallops, and oysters. Raw chunks of tuna are also a great choice.

These protein-rich foods provide the most natural meal substitutes for betta fish.

Human Foods That You Must Never Give to a Betta Fish

Following are some foods that you must never give to your betta fish, no matter what happens:


As mentioned, betta fish are carnivores. If you add plants in their tank and expect them to live off them, you’re wrong!

Betta fish will die due to a lack of protein and starvation if you rely on plants to feed them.

A Betta Fish’s Normal Diet

Betta fish need high amounts of protein in their diet in order to survive and live healthily.

Because they are carnivores, betta fish eat shrimp, fish, bloodworms, and other small creatures when they are in their wild habitat.

Since you are keeping your betta fish at home in an aquarium, you must ensure that you replicate their wildlife diet. You can purchase fresh or frozen food options from a local pet shop or aquarium store.

Some foods you can feed your betta fish regularly are:

White worms

Blood worms

Glass worms


Mosquito larva

Fruit flies

Shrimp (brine, fairy, opossum)



If you are giving your betta fish dried versions of the foods listed above, make sure you soak them in water before giving it to your fish. This will prevent the notorious bloating and digestion problems.

If you wish to feed pellets or fish flakes to your betta fish, please do so but only occasionally. Commercially-produced pellets and flakes can cause digestive problems for your betta fish.

Find high-quality fish flakes and pellets that support digestion and do not cause constipation or bloating. If you are giving pellets, soak them in water to ensure complete digestion.

It is advisable not to buy large quantities of commercial fish food since most foods have a minimum expiration time.

Please do not use any processed food (packed or tinned) for more than 6 months after opening it.

Feeding Tips for Betta Fish

If you want a healthy and happy betta fish, you must follow these extremely important tips we will share with you in this section:

Make a Feeding Schedule

Feed your betta fish twice a day, after every 12 hours. For example, feed your fish at 9 am and then at 9 pm.

Even if you change the time, no need to worry. As long as you keep a 12-hour window before you give your fish its next meal, you’re doing good.

It is fine to give these occasionally. However, since bettas are carnivores, their diet must consist of 75% to 90% meat-based food options.

Do Not Give Too Much Human Food

As discussed previously, giving too much human food must be avoided since bettas cannot survive solely on human nutrition.

Digestion problems can also arise due to human food consumption. Give human food occasionally, as a treat, perhaps once or twice a week.

Add Variety

If your betta fish is a picky eater, give it a variety of different foods. While frozen and dried foods are the best options (free of bacteria), you should also give raw or fresh foods to spark your betta’s interest.

Feed your betta fish according to its nutritional requirements. Like all animals and even humans, betta fish have specific needs that you must fulfill as the owner.

Bettas, like all other fish, have very tiny and sensitive digestive systems.

Keep their food options as close to the ones they get in their natural habitat, and you will have a healthy pet for a long time!
