I just found my DG wedged in one of the holes in one of my decorations. I was able to gently push him out. I have no idea how long he's been there. But he's torn up pretty good from thrashing trying to get out. He has scales missing by his top fin and his top fin isn't red anymore. It's his belly area that's bad....he has a spot that looks like it's bleeding. I'll be surprised if he lives through this. What can I do to attempt to save him?
