To care for a Betta fish, a person will need to be able to create a proper living environment for the fish, feed the fish appropriately and ensure that all male Betta fish are kept away from other Betta fish (the males are oftenÂ aggressive).Â Betta fish that are properly cared for can live anywhere from 2 to 4 years.
The Betta fish tank should have its water changed once per week and should not have any algae growing inside. The water should be kept between 74 and 85 degrees Fahrenheit. It should also be within a pH of 6.5 and 7.5, with 7.0 being the ideal pH level. Each individual tank should be at least a half-gallon or larger. The tank should feature either live or plastic plants, with gravel on the bottom of the tank. Betta fish have also been known to jump out of tanks, so it is important to keep the tank covered.
Most Betta fish prefer to eat 6 out of 7 days of the week. The skipped day gives the Betta's digestive system enough time to recuperate. Betta fish should eat a small amount of food twice per day. The exact amount will depend on the type of food given.
