I moved one of my cyno sp hara's to the refugium b/c he was getting bullied by the dom male. I was planning to find him a new home. When I came home yesterday, he has a huge wound on the right of his head. It's perfectly circle and there was flesh hanging from it. It's white under the wound. He's the only fish in the fuge and the only thing in there was a heater. Has anyone ever had a fish sit next to a heater long enough to burn themselves? I'm thinking maybe he was hanging out there and it turned on and he didn't know...? I removed the heater and threw a few rocks in there to try and make him comfortable. Just curious if anyone had a fish burn themselves before. Quite literally.
