1. The first step is to check the water condition, the temperature should be between 76° and 85° F, and the water should be slightly acidic with a pH of 6.5 to 7.5.
2. Then, change the aquarium water regularly every 2-4 weeks; just replace 10-25% of the water.
3. Provide lighting, as lighting can help control algae.
4. Avoid combining Delta Tail Betta with other betta species.
