Sandbox is one of the shallower dive site diving Opal Reef, making for a great last dive of the day. There’s a well covered coral top and down at 10m coral structures in a sandy base. Inside these structures you are bound to find something interesting, like this Spotted Sweetlips.

A lizardfish – sometimes mistaken for a grub fish – as they sit on the coral tops in pretty much the same way.  But look at this guy’s face – just the face – it’s just like a lizard or a snake.

Finally, like most dives on the reef, there’s a great coral top to do your three minute safety stop.  If only the boat didn’t depart at 3.10pm – I could stay here all day.
