Alright, so i noticed today my betta's fins were looking sort of raggedy.... is it fin rot? And if so, what's the best way to treat it?
He's around four year's old, and lives in a filtered one gallon. He still eats vigorously, and is active. As far as I can remember he was never sick. I haven't done anything yet....I'm not sure what to do. PLEASE HELP!!!!!!
Can you tell from these?
