Thanks for the props Dreamer, they look great in your setup! That last shot is great:thm:. Don't worry about the sand, as soon as they get more comfortable in your tank, you'll be amazed at what they can accomplish while you sleep! Just recently, they were doing alot of "housekeeping" in my tank.
FWIW, I do have 7 more, but they are too small to sell yet. Probably a couple of months yet.
