Adding a background to my tank. Does the background go inside the tank or on the outside and what should i make it stick because it was just the actual background that came in the packaging so help me out guys?:nilly:
Not really.
It goes on the outside.
There should be a peely-offy on the back.
If not, tape works good.
Tape might be preferred just in case you ever get tired of it, its not a pain in the anal area to remove it.
