Well, i will probably be going to the petstore tomorrow (i need to buy some fish food
) and they have one out on display, maybe i can take some measurements or somehting. Because the tubes do look small, i'll see.
The other one i was thinking about, was the Habitrail Playground. It is basically the same as the other habitrails, except different colors. I would also buy two cages, and attach them.
Thanks for your help,
