Anyone know what this is? All of the sudden my eel has this huge white patch that looks like fin rot. Yesterday he was swimming completely fine and had no scratches on him, today he's chilling at the top of the water and this huge white "scratch" at the end of his tail. I'm assuming its a bacterial infection, if so, what meds should I be medicating with? I also did a huge water change. I have a tire track eel and they have never fought and leave each other alone. Also 4 bichirs with them. Please help!

Temp: 80
pH: 6.8-7
ammonia: 0
nitrite: 0
nitrate: 5-10IMG_6146.jpegIMG_6145.jpeg

Could be a form of fin rot. Can try api fin and body. Try half dose at first then add other half same day. But a few 4-6 hr apart just to see the response.
