I had a diving class and did three tank. I went out to see the Adolf's bush a 1oo ft down wreck.and a near by reef, two sides. Really fun when a fellow diver assisted me by blocking in one side of cavern and the Goliaths (he was trapped in the large cavern) only other way out was through me. I quickly caught on and we had massive fish trapped between us, he pinged the water pretty loud with a underwater noise they use for protection. He looked mighty confused, almost head butted me to get out, really fun to be head to head with one of these gigantic fish defiantly some of my most memorable highlights of ocean experiences.
