I've collected a good pile of pretty decent size rocks over the past couple weeks and I'm looking to make a rock scape with them. A few questions...
1) do I need to put egg crates or something else on the bottom of the tank?
2) is it advisable to glue the rocks together so they don't move?
3) any thing special need to be done to the rocks to make them aquarium safe?
