Ok, I had one reply to my Question, which was: would it work if I turn 36L-18W-15T on it's end, and use the black, wire/bar lid, would crix get out. The reply said the crix would get out (which, after looking at it, I can see that they clearly would). If I used a mesh (like a screen for your window, not the bars) for a lid, would the tank still function ok, even if it is on his side?
Thanks
Joe
