Lifespan and Diet
Normally betta fish live to be 2-5 years old, but some betta fishes live to be nearly 8 years old. However, when purchasing from a pet store, it is not always possible to know how old the fish is when you take it home. Male bettas living in laboratories with large individual tanks and daily exercise have lived 10 years or longer.
Carnivorous, the betta feeds on zooplankton and mosquito and other insect larvae. Domesticated bettas will feed on bloodworms, daphnia, and brine shrimp. Betta pellets are typically a combination of mashed shrimp meal, bloodworms, and various vitamins to enhance color and longevity. For variety and fiber, bettas may also be fed finely chopped vegetables high in protein such as soybeans, green beans, broccoli, corn, or carrots.
Bettas are primarily surface feeders, that is their mouths are upturned, so any food items added should be able to float on the surface of the water.
Bettas fare better with a large variety of foods and will often show brighter, richer, and deeper colors if they are fed a wide range of foods. They will also heal much more quickly from fin damage if their diets are high in protein and fiber.
