Blue Throat Triggerfish digging in sand

[jamesrb]

Hey Everyone....
I've had a Blue Throat Triggerfish for about two months now and just yesterday started noticing a 6-7" hole in my sand bend near the right rear of the tank. sand was all over my corals.
I cleaned it up and figured it was a just a rogue Nero 5 pump... well it happened three more times so I then put a camera on it and watched from a distance...
It was my triggerfish! he would lay on the sand bed and move his tail until there was a huge mess of sand all over!

he appears healthy and in good spirits!.. any ideas?

Thanks,
James Bishop
