Okay so I bought my blue veil tailed betta at petsmart almost 8 months ago and have never had any health issues besides minor fin rot and constipation, both of which were cured.
As of about a week ago, I came home to my betta floating on his side hiding and barely moving. He usually comes up and wiggles at me until I walk away. Strange bubbles kept coming out of him and when he pooped it was stringy and white/clearish. Now he seems as if he is constantly sinking and it's hard for him to stay up near the water surface when I feed him. Other than feeding time, he is very lethargic. I hardly ever see him move. He has also developed another case of fin rot.
