use arrow keys to move eat the fish (only your mouth can eat them you can't eat them with other parts of your body) avoid the dolphin
I couldn't find any resources that describe natural predators of roi but I know dolphins eat lots of fish and one was in my dig box so I chose that. the roi eats lots of reef fish and the ones in this game are generic orange ones. go to tinyurl dot com slash digboxslideshow for more information
