How Long Do Betta Fish Live 

WITHOUT FOOD

Bettas are normally very easy to take care of and it’s important to know how to take care of betta fish, especially if you plan on leaving it for a few days.

Bettas can live without food for up to 14 days thanks to their small stomachs and instincts from their wild habitats.

Surviving isn’t thriving, though - after 4 to 5 days with no food bettas will start tapping into their reserves and enter the beginning stages of starvation. 

Because betta fish have such small stomachs, they really don’t need a lot of food at any given time. In fact, it’s healthy for bettas not to have an overabundance of food at any given time.

Overeating in betta fish causes issues like bloating, constipation, disease contraction, swim bladder issues, and even obesity.
