Hello all! I posted a thread a few days ago called "adopted a sick betta". This is a continuation of that, but I wanted to make a new thread because I really need some help. The betta I adopted was very lethargic and laying on his side at the bottom when I received him. He's perked up a bit, and since he's swimming a bit more I got a closer look at him. He's got lesions on his head! My first thought was hole in head, but I know that's not very common in bettas. I'll post some photos. I'm trying to decide the best course of treatment. I'm still maintaining 40-50% water changes daily, and I have gotten him to eat twice now. It was an unexpected adoption, so I didn't have a cycled tank for him, but the ammonia and nitrites are low due to the daily WC. (Probably not 0, but under .2) Please, any help would be appreciated! I'm really trying to help this little guy.
