Unstable Feeding Schedule

Don’t worry if you keep fish in the office and can’t feed them on two weekends. Just make sure to give them food at least 5 days every week. It’d be even better if you let them starve one day per week.

Betta fish can live without eating anything constantly for up to two weeks, but never try to test them.

When Betta Fish Adapts To A New Environment

Your pet fish might be still tired when brought from the aquarium store, which is why they do not eat anything.

In fact, pet owners shouldn’t feed their fish during this time because it probably causes indigestion or bloating to them.

It’s best to feed your fish after 12 to 24 hours after bringing them home. For mature betta fish, start to feed them once per day with a very little amount of food.

Watch how your fish enjoy their meal to know if they eat the whole amount of food or if they like it. Accordingly, adjust the right quantity of foods per meal for them.

Once your fish is getting better, feed them twice per day, at least 5 days per week.

Overfeeding

Betta fish is extremely gluttonous. When healthy, they have a tendency to try to eat the whole amount of food you feed them.

This makes most beginner fish keepers assume that their pets must be very hungry, so they feed the fish more. Of course, this is not recommended! Overfeeding might cause bloating, indigestion, or some diseases to fish. In the worst case, they die.

Solution:

How to know if you’re overfeeding your betta fish?

As stated above, always observe how your fish enjoy their meal. If you find there is much residue left afterward. It is a clear sign that you should reduce the amount.

For example, if you feed them four food pellets and they can’t eat the whole of them, decrease to three. Remember to remove food residue in your aquarium tank to avoid bacteria, which might lower the water quality, leading to some unwanted diseases.

How do I find out the right amount of food for fish?

Determine the right amount of foods per meal to feed your betta fish.

From our experience, betta fish’s stomach size is the same as the size of their eyeballs, which is commonly equivalent to three small saltwater shrimp or three feed pellets at a time. Don’t feed more than that!

If you use dry foods, remember to soak them in fresh, chlorine-free water around 3-5 minutes before feeding.

Otherwise, foods will swell up in the fish’s stomach, causing floating or death in fish.

Your Betta Fish Might Get Sick

If the fish swallow food but spill it out right then, they might get sick somewhere. Here are some common diseases in betta fish:

Solutions:

First, let your fish starve for 1-3 days to clear out their digestion system. Frequently observe them during this time, especially how they poop.

Add fiber-rich foods to their diet, such as daphnia and thawed frozen pea pieces.
