For some reason my little yondus left dangly bit (name escaping me right now) started to shrivel up I started doing 2 100% water changes a week (i have 1 gallon don’t worry I’m getting it changed soon) it was weird water parameters were good but whatever might help now it has started to uncurl slowly and is almost back to normal!
For me. It’s a future case. I bought a Bichir and I noticed bleeding in the bag. Next thing I know he’s missing a fin and the fin wasn’t in there. He was hiding from the Albino Bichir ( and possibly a tire track) in the tank where I got him but idk. I read they can regenerate fins as juveniles. So we’ll see
