How to remove foam backing??

[Java]

Does anyone have any idea how to get rid of that fake (foam?) backing on the Exo-Terra Nano Glass Terrarium? I am now using this setup for my tarantula and it's become problematic (she can't stand it and will crawl every where BUT on it. Plus, it'd give me more room.) I'd love to learn how to take it out.

Thanks! Any ideas are better than none!

After removing the screen top; just pull background forward (toward door) on one side only. Once it's diagonal to enclosure you can pull it out from the top. Good luck !

Thanks so much! I usually avoid these types of tanks but it was cheeeeap, lol. Thought I'd have to heat up the glass or something.

Thanks again!
