Bettas thrive in warm (around 78°F), filtered, and well-oxygenated water with a pH level between 6.5 and 7.5. The tank should be at least 5 gallons and should have live plants and hiding spots. Live plants provide oxygen, improve water quality, and give your fish a place to hide and explore.
2. Maintain good water quality:
Regular water changes (at least 25% once a week) are crucial for removing harmful waste products and preventing water quality issues. Always use a conditioner to dechlorinate tap water before adding it to the tank.
3. Feed a healthy diet:
Bettas are carnivores and require a diet of live or frozen foods such as brine shrimp, daphnia, and bloodworms. Feed your betta several small meals throughout the day, and avoid overfeeding.
4. Avoid stress:
Stress can compromise a betta's immune system, making them more susceptible to diseases and infections. Avoid overcrowding the tank, sudden changes in temperature, and other stressful situations.
5. Monitor health and watch for signs of illness:
Regularly inspect your betta for signs of illness, such as lethargy, clamped fins, loss of appetite, and erratic swimming. If you notice any signs of illness, take your betta to a veterinarian.
