The Sharks are members of the Fishtank crew who enter the house on occasion to perform various tasks, including messing with the contestants, who are the opposite of the Sharks as they are the "Fish."
The Sharks are best recognized by the masks covering their faces and their solid color appearances. During Season 1 and Season 2, there were at least three sharks noted to have appeared in the house during the show, all of whom were played by members of the production crew.
- Red Shark
- Black Shark
- White Shark
Often the Shark roles rotate as different crew members wear different colored-suits. In one instance from Season 2, Jimmy briefly wore the White Shark suit before he took off the mask and his one-day return as a freeloader was revealed. Another instance from Season 3 was when Jobe wore the White shark suit
