natgeowild: ""I was able to swim with the grouper during the release. It's an incredible experience to be able to swim with a 300 pound fish and despite what some people say the grouper are gentle giants. After we had tagged them I would hold the fish and swim away from the boat then push it down and guide them to deeper water. I loved seeing them swimming back down to the darker blue water beneath the boat." --@ZebHogan host of #Monster Fish. New episode tonight at 9/8c."
