Betta, or Siamese fighting, fish are among "the most popular freshwater aquarium fish in the world," PetMD reports. Native to southeast Asia, this species is known for its range of vibrant hues. There are over 70 different types of bettas out there.

The freshwater fish is a common pet since it is relatively easy to care for. When given proper care, betta fish can live for a while.

But what is the average lifespan of a betta fish?

How long do betta fish live?

In captivity, betta fish typically live two to five years, according to Adelphi University.

Some betta fish, however, have lived longer. PetMD reports that the fish can live between five to seven years in ideal conditions. A few fish defy the norm and live up to 10 years of age, according to Spruce Pets.

A betta fish's lifespan can be impacted by the care it receives, WebMD reports. Bettas may live longer if their tank is clean, the environment is calm and their diet is healthy.

How often to feed betta fish

Betta fish should be fed at least twice a day, Aquatic Veterinary Services reports. Their meals should also be spaced out by six to eight hours.

Bettas are natural carnivores, so it is important for them to maintain a high-protein diet. PetMD recommends feeding fish pellets over flakes to them.

A betta fish's feeding habits will be based on the temperature of its environment. The tank water should be around 78 to 82 degrees Fahrenheit, according to Aquatic Veterinary Services. If the temperature is out of this range, your betta fish is at risk for several health issues.

Do betta fish sleep?

Like other fish, betta fish do "sleep." But fish do not sleep in the same way mammals do.

Fish rest by slowing down their activity and metabolism, the National Oceanic and Atmospheric Administration reports.

Another difference between a fish's sleep and that of mammals is that fish rest with their eyes open. Unlike mammals, fish do not have eyelids, according to Aqueon. So, a fish may appear wide awake while they are actually sleeping.
