I saw this very interesting looking fish at my LFS. It was marked as a kling fish. It was ugly as sin but would pop its head out of the water to my fingers and it would swim right into the hand of one of the workers. He said it will eat right out of his hand. I've been looking for any info on this fish and I can find a single article or even a reference this this fish. Anyone have any info on this "Kling Fish"?
