I don't know about that...while she looks nice and green here, I actually like the visible body pattern when I had them in the 120g with the Silica Sand. They show it once in awhile, but mostly dark. They've probably been in with the Black Sand for over 8 months. Here's another shot from May '12

Super black and muddy on this pic, is it the camera???? I think most of those who collect the upper jaw shoot for the greens but i would have to agree with you both i like patterns more hence the reason why I'm keep the lower jaws. Maybe you should try some of the MOHAWK I believe this stuff is good for both upper and lower.
