i have them set up in cadbury tubs.....not sure if you have them in the us....from watching the Ralph Davis vids i can see that they are not as big as the tubs he sets his hatchlings up in.... im not a messer they have been left alone from day one....its not too much of a problem now anyways as someone has just been round and bought all but 1 of them, maybe someone else will have more luck with them....
