Here's my crocea I got about 2 weeks ago for $30.
This is the best image I can get from the top down, my cords are all interconnected behind my tank, so shutting off pumps is a hassle (that and the lights don't cooperate being above the tank and all with reflections), I'll have a much more user friendly power setup as soon as I move my tank (so whenever I get off my butt and pull power to the room). It's quite amazing the color difference though, but I am NOT setting up one of those angle'd front tanks just to see clams from above.
