My Betta will be 2 years old this coming January and recently, in the past month, I have noticed that he has become very lethargic and is having a hard time swimming. It seems like when he tries to swim to the surface he is struggling and almost sinking.
I read that I should try fasting for 3 days and then if that does not work trying one more day and seeing if that helps. I stopped feeding him his regular hard pellets for 4 days and then tried feeding him small amounts of frozen peas. Neither of these have helped. He is still sitting on the bottum of his tank. I tried a water change and have tested the ph of the water.
I don't know what else to do! Please help :(
