My betta fish has been healthy for the past 7-8 months that I had him but lately his tails are shriveling up and he seems slouchy. His light broke so it's been a bit dim in my room. Also, the water I use is from our well. My parents own an oyster business so chlorine tests are taken every month for the health department. Besides that, I still use water conditioners to be sure. What should I do? Suggestions? I'm worried about him I changed his water today & put him near a lamp and he seems to be swimming a bit more and moving his front fins really fast. He's still eats normaly, 3-5 pellets in the morning and evening. Still, any suggestions about if he's sick? I wish he could tell me what's wrong himself ((.he sits in the corner at the top or bottom or by his plant. I Don't know the temp. But I'm going to in the morning. Anything else I should pick up?
