I first noticed my fish looked a little "different," maybe not bloated, about 3 weeks ago. About a week ago I could tell he was definitely bloated. I tried fasting him for the past 3 days, but he still looks the same.
He's still just as active as always, and his poop looks normal. He only poops once a week, but that's how it's always been. Yesterday his ventral and anal fins started trembling, and they're still doing it. What would be the best course of treatment?
