Habitat and Tank Requirements

The Clown Betta fish is a tropical fish that requires a stable and warm environment to thrive. The ideal temperature range for the Clown Betta fish is between 76 and 82 degrees Fahrenheit. They also require a pH level between 6.5 and 7.5, and a water hardness between 5 and 20 dGH.

When it comes to their tank, the Clown Betta fish requires a tank that is at least five gallons in size. A filtered tank with plenty of plants and hiding spots will provide a healthy environment for your fish to thrive. They are also known to be solitary fish, so it’s recommended to house them alone.

Feeding and Care

The Clown Betta fish is an omnivore, which means they can eat a variety of foods. They require a well-balanced diet that includes both protein and vegetables. They can eat commercial fish food, but they will also enjoy live or frozen foods like brine shrimp or bloodworms.

Clown Betta fish require regular maintenance to keep their tank clean and their water quality optimal. Regular water changes are essential, and filters must be cleaned on a weekly basis. Ensuring that the water quality is excellent and the tank is clean is the key to keeping your fish healthy.

Once the male has built a bubble nest, he will begin courting the female, and when they spawn, the female will release the eggs, and the male will fertilize them. The male will guard the eggs and fry in the bubble nest, and when the fry hatches, it is essential to feed them appropriately and carefully monitor the water conditions.
