A pinky fish (Pomadsys olivaceum) hides in the shadows of uShaka Marine World’s shark tank. It is a common bait fish found along the South African coast and in estuary systems. The pinky fish is known by a few names in different parts of South Africa; piggy, olive grunt, olive grunter and, of course, pinky. These other names are derived from the grunting noise it makes when caught. It is a good fish to be used as live bait and can be identified by the black spot on its gill plate.
