My DIY Styrofoam Background (and tank)

[SRC]

Had to wedge it down with the filter foam..but it has been in there for 4 days and Moo (that's my new girls name lol..it's Thai for Pig..since she was my guinnie pig lol) is still happy as a lark. And the cave is still holding up nicely...not soggy parts or flaking.
