I saw one at an LFS in September, he said it was the first one he recalled seeing. He wasn't sure how often they appear on his order sheets. I would have got it but it just wasn't moving at all. I know cats are inactive but I had him move it from the back of the tank to the front so I could see it, it was behind a filter. Once up to the front I watched it for a while and it never moved. I just didn't want to risk it with a $40 fish, it was around 3".
