2. Water Temperature:

Maintaining the water temperature between 78-80°F (25-27°C) is important for the fish’s comfort. You can use a heater and thermometer to control the temperature.

3. Filtration:

Bettas prefer calm water, so use a gentle filter to maintain clean water and proper aeration. Avoid strong currents.

4. Tank Décor:

This is really important because Bettas love isolation. Use decorations like plants and caves to create hiding spots for Bettas. It not only reduces their stress but also creates a natural resting environment.

5. Water Quality:

Regularly test water parameters for ammonia, nitrites and nitrates. Also, you must change about 25% of the tank water weekly to prevent ammonia and nitrate buildup. Make sure to use conditioned water at the right temperature while changing.

6. Balanced Diet:

Evaluate your Betta’s diet and feeding habits. Provide a high-quality Betta specific diet which may include pellets, flakes and occasional live or frozen treats like brine shrimps or daphnia. Two small meals a day is sufficient for them. Avoid overfeeding them to prevent obesity and water pollution.

7. Avoid Overcrowding:

Bettas are territorial and have a tendency to become aggressive towards each other. So, keeping only one Betta per tank is better.

8. Quarantine:

If you’re planning to add new fish to your tanks, make sure you quarantine the new ones in a separate tank for a few days to avoid any risk of potential diseases. Also, if you suspect any disease in one, consider moving it to a separate tank to prevent the spread of illness to other fish.

9. Observation:

Keep an eye on your Betta fish from time to time. Observe them for any signs of illness like changes in behavior, loss of appetite or discoloration basically the ugly look. If you can detect anything early, treatment will also become faster.
