So, when I received my Ikea catalog a month and a half ago, I saw an awesome item in the storage section. To me, it looked exactly like a snake rack. It was inexpensive ($40 for the rack, $2 each for the tubs), so I decided to see what it was like. My aunt was going near an Ikea and I asked her...

Thats a Very good Idea.
Its amazing what you can pick up from Ikea these days.

Is there any pics on it when u have animals in it?
How have you solwed the heater?

I am assuming that if you want to give a temperature gradient to all the animals the same, including the ones in all sections of the dividers, then you would have to wire a strip of heat tape and attach it on the bottom on one side for each tub since it doesnt have a shelf below it to attach the heat tape to. Might make it slightly hard to remove all of the tubs and clean them, if they are attached to heat tape and cords. The more you accidentally yank on cords and connections, the more of a risk you have to just breaking it off and having to rewire [ive had to do this my fair share of times from when I used to wire 10 gallon tanks individually]
