Typical clown knifefish dude. No two are alike. Personaly I like royals better (thats what I own), little pricey but worth it. Just keep looking around and eventualy you'll find a pattern you like. As for the oddly shaped patterns, you dont see it too often, in most cases there pretty oval or rounded from what iv seen. So if you want that certain pattern it might take a while to find. I suggestyou look at royal clowns.
