How to feed your betta fish. It is recommended to feed your betta fish two to four pellets, once or twice per day. Pellets expand when placed in water and are very filling for your betta fish. Freeze-dried or fresh food can be substituted for their pellet feeding 1 to 2 days per week.

How many days can a betta fish go without food?

As we've just mentioned, betta fish can survive between 10-14 days without food. However, there are some major factors you should consider before leaving your betta fish unattended for such a long period of time.

How much do you feed a betta fish?

Anything between 4 to 6 pellets a day is a good amount to feed a betta. This measurement can vary as manufactures produce differently-sized pellets, so take this measurement as a rule of thumb. Aim for about 1.8 grams worth (for an adult betta) if you are unsure.
