* Low Oxygen Levels: Bettas are labyrinth fish, meaning they can breathe air directly through a specialized organ. However, they *should not* need to do this regularly. If they are frequently gasping at the surface, it means the water in their bowl is not adequately oxygenated.
* Poor Water Quality: Low oxygen levels are often a symptom of poor water quality. This could be due to overfeeding, lack of regular water changes, or a buildup of ammonia and nitrates.
* Small Tank Size: A bowl is rarely large enough to properly house a Betta. Even a small tank should be at least 5 gallons.
What to do:
1. Immediate Action: Perform a 50% water change immediately with dechlorinated water.
2. Add an Air Stone: An air stone will help to oxygenate the water more effectively.
3. Larger Tank: Invest in a larger tank (at least 5 gallons) with a filter.
4. Regular Water Changes: Do partial water changes 25% weekly.
5. Adequate Filtration: A small filter is essential for a Betta tank to maintain water quality.
6. Proper Feeding: Feed your Betta a small amount of high-quality food once or twice a day. Don't overfeed!
Important Note: If your Betta is showing other signs of distress, such as lethargy, loss of appetite, or clamped fins, it's essential to seek veterinary advice immediately.
