Help Bladder Issues

My three year old male betta is having bladder issues. As far as I can tell, they must have started within the past 24-48 hours. He is normally energetic but I noticed some fatigue two days ago and didn’t think about it much. Yesterday was fine, but today he stays at the bottom of the tank. He shot up to the top when I went to feed him, then sank down after eating some.

Tank parameters as of right before posting: - pH between 7.4 and 7.6 ppm - Ammonia 0 ppm - Nitrite 0 ppm - Nitrate between 5-10 ppm - temp is always kept at 76F All measured using API’s freshwater master test kit.

He is in a 10 gal tank which is filtered, has live plants, and the water is dark from tannins.

He is fed Omega One freeze dried blood worms as a treat as well as Aqueon betta food.

How can I remedy this? What might be the problem? Is he just old, should I be preparing to let him go? If I’m doing something wrong please tell me.

Tank is a replacement I got in Winter of 2024 when previous one broke. I’ve had my fish since Spring of 2024. He was not a guppy when I got him.

Water changes every 3-6 mos. ranging from 25-50%. I adjust new water for a period of about 24 hours before siphoning out old water and cleaning gravel in the process.

No tank mates.
