The L200 L# is split into two different species. Hemiancistrus subviridis, and baryancistrus dematoides, b. dematoides is the high fin varient in your avatar. The color dictates alot about the location of the fish. The farther north the more black the L128 will be, and the farther south the more blue-green they become. For L200s from grayish green all the way to a mustard yellow. I started a thread back there somewhere that has all that information; I'll try to find it and post it up. As to spots, they are just like human finger prints, no two are alike. I recently lost an L200 that only had 8 fully developed spots on his body, and he was 5.5" long. You can find that in the Breeding L200s thread. I'll link you to that specific fish in a second.
