rock wall, glue it or egg crate?

It is a big tank, 180g tall. I can actually sit in it, if it were not for the bracing. I was scuba diving in Cuba and saw an amazing wall of coral. I would love to recreate something like this. When I saw this tall tank for sale (used for an amazing price) I grabbed it right away. Then I shall get out my mask and have a flashback LOL. Later I will drink rum and tell tall tales ... dare to dream!
