My betta fish seems to be sick and has been like that for the past two weeks. He spends most of the day laying at the bottom of the tank and is not responsive. He goes up for air occasionally and is still eating.
I thought maybe he had swim bladder disease so I did not feed him for 3 days, but he did not get better. I noticed his color is not the same and his fins look rugged, so I assumed it was fin rot. I changed the water and gave him antibiotic for 7 days but he isn’t any better.
I’m having a hard time diagnosing him and figuring out how to treat him at this point. Does anyone have any ideas?
