I thought my betta had fin rot so I have been treating him with Maracyn 2 for the past 3 days. Yesterday I noticed him bending around like he was trying to get his tail but I couldn't tell if he was actually biting it. I also noticed some blood at the end of the shredded fins. His fins look very shredded. I am not sure if this is fin rot. I would really appreciate some help. I am worried about him.
