i cant decide between a clean spotted clown knife and a black aro, both magestic beutifull and very awe inspiring. i had a clown knife a while back, he was one of the best fish i have ever had, maybe my oscar and pistus where better, but he was absolutely stunning, and live an amazing 9 years, i bought him from a guy who had him for 6 years in a 250 gallon pond and he only got 5 inches, so he sold it too me and he grew to 7.5 inches in his last 2 years with me, but then we gave him to a guy with a 1200 gallon southeast asian monster tank at the lfs(display only) and he lived another happy year.
