Is this stone safe to use?
Will hot glue be safe?
Other then boiling the rocks is there anything I need to do?
Any advice or tips would be great.
also if any one has pictures of a good design that would super cool!
You could probably get away without the glue. Just place them CAREFULLY in the tank and make sure they are secure. You don't want one them falling against the glass.. If you really want to 'glue' them, I would use Aquarium silicone or 100% silicone(cheaper) instead. For designs, Google images is a good place to start.. The flagstones, pour some neat vinegar onto it, if it bubbles, then I don't think it's compatible. I'm sure someone else can correct me on that...
