longer snout, no stripes, bigger tail, larger teeth, 4 extra teeth in back of mouth (although nearly impossable to see at juvie size), and usually their eyes(not pupil) are lighter in color. I owned one years ago, around the same time as supajap, but I live in Nor-Cal. I picked it up from a LFS that priced it as a regular ATF. Kept it in my 60 gallon for a few months and tryed to sell it because I knew it's potential size. Since I didn't have a digicam back then, didn't have many people interested in buying, eventhough my home was open for anyone to come see. I guess they were just way too rare back then for anyone to believe I owned one. Bad thing was I ended up selling it for around $150 cuz of the non believers. Tank was way too small to hold on to it. I believe it was back when WW was Predatory. Anyways, moral of the story...Keep your eyes open at your LFS. You never know what you might find.
