A scuba diver films one of several large 3' - 5' long Potato Cod (Epinephelus tukula) that frequent the famous 'Cod Hole' dive site on the Great Barrier Reef in North Queensland, Australia. This fish is being cleaned by several Bluestreak Cleaner Wrasse and is resting on the ocean floor while it is happening.
There are frequent feedings of the Potato Cod's at this site, though in general only one or two of the Cod participate.
These grouper can grow as large as 7' in length and are generally docile and curious, although the occasional aggressive incident towards scuba divers have occurred.
