swim bladder

If your betta is swimming sideways, it’s likely struggling with balance or buoyancy issues, often caused by swim bladder disorder, infections, or injuries. Poor water quality and stressful tank environments can also disrupt normal swimming behavior.

You’ll want to check the water parameters, tank setup, and diet to help your fish recover and stay healthy. Keep an eye out for other stress signs, and further insight can help you support your betta’s wellbeing better.
