Betta Fish Life Expectancy: Increase Their Lifespan

Betta fish (Betta splendens) is a species of tropical freshwater fish belonging to the Siamese fighting fish family Betta. Commonly known as Siamese fighting fish, betta fish originate from Thailand and Myanmar. These small, colorful, and interesting fishes are easy to maintain and care for.

Betta fish typically live two to five years in captivity. In the wild, most bettas will live up to roughly two years only. With these said, betta fish obviously can live longer inside an aquarium than in the wild where they need to constantly seek food sources.

Purchase Healthy Bettas

One of the best ways to lengthen your betta fish’s lifespan is by purchasing healthy Bettas when possible. Bringing a new, properly-sized aquarium home can be stressful for any fish and can cause them to lose their energy, appetite, and overall health. Simply keeping your bettas in an appropriate size tank will help keep them healthier and reduce conditions such as stress which could lead to shorter lifespans. Moreover, make sure the tank has a lid to prevent escape.

Provide Proper Environment

The key to a long lifespan for any fish is providing them with an appropriate environment. Bettas need clean water and plenty of hiding places to feel secure and avoid being picked on by other fish. A healthy diet is also important, as bland aquarium food can lead to digestive problems that can shorten a betta’s life span. Finally, be sure to give your bettas regular behavioral enrichment such as hiding objects or providing bubbling water to keep them amused and stimulated.

Use Proper Betta Fish Tank Decorations

Betta fish can become stressed if their tank is too bare, so it is important to provide them with hiding places and decorations.

Separate Male Betta Fish

Betta fish can become aggressive and territorial if they are kept together in the same tank. It is important to keep male betta fish separate from each other so that they do not attack or harass each other.
