So as the topic states can I put or line the walls of my tank with the plastic fish tank background? Would it bother the tortoise since it looks like woods and such?
I have a vinyl background with a jungle on it and my tort isn't bothered by it as far as I can tell. He doesn't try to walk into it or something. And it looks cool!
Agreed. I would say it is common for those of us who have to use terrarium/vivarium type enclosures to use the fish tank backgrounds, just because they are cheap and easy.
The aquarium type decorative sheets are generally attached to the outside of the glass with some sort of tape.
I would not attempt to attach it to the inside of any enclosure. (Just for safeties sake)
