This is Gunner.
I found him at my LFS
in a tiny display bowl covered in fuzz, with fin rot and not moving unless you tapped the glass. That was Friday. I thought about him all night so I went back and to get him Saturday morning. They didn't want to sell him to me because they 'don't sell sick fish'. After talking to the manager they bagged him up and I brought him home!
The fuzz cleared up overnight with clean water and salt. His fins have stopped rotting and he has the biggest apatite. He's on my night stand and every morning since I got him a wake up to him 'wagging' his tail and swimming happily. I'm so glad I got him. His personality is shining now he's feeling better. I hope he makes a full recovery. He's fast becoming my favorite fish!
