As of this morning, King Fishy looks soooooooo much worse. Almost all his fins are turning black. Piece of his tail, both full fins under his head, half his tail and it's starting on that fin bellow his tail from his body down. It's looking terrible. He seems to be breathing fine, but he looks like his body is rotten. He had been changing to a gold color around his gill, I was told that it was him just changing colors. Well...that gold color is almost completely gone and everything that was changing to the gold/green is now rotted. Well, maybe not around the gill. I can't really tell. He's a very dark blue/black there now. Should I put King FIshy out of his misery? This can't be good for him.
