I think my betta has fin rot. I'm pretty sure it was from a plastic plant I used to have in his bowl before I learned all about fishkeeping. He's been in a 10 gallon for a few weeks but I recently noticed the fin rot getting worse so he's I'm quarantine. He's still acting perfectly normal but his fins keep getting worse. Can I treat him with just salt or do I need an antibiotic. Here are pictures of him when I first got him and today. Please help!
