The Reef 2: High Tide (2012)

Trained in the skills of sea power, Pi the fish can fight a shark, sink a squid or batter any random predator that ever threatens his friends and neighbors on the reef. Unfortunately, being the only hero in town can take its toll, especially when a group of sharks declares that the end of the reef is soon at hand.
