When I was doing a lot of dives on the Deliverance several years back there were a pair living under the wreck's bow winch. They would come out to be petted when I swam up to them. I could lay my left hand underneath the fishes body and stroke along the back with my right like patting a dog. Growing up commercial fishing and seeing them out of the water (they behave much like a rabid pitbull when taken from the water) it took me quite a while to muster the courage to approach these animals closely underwater, but they are extremely docile when in their own element.
Hopefully, now that they've been placed on the protected list, they'll start to make a comeback and we'll start seeing them more often on dives again.
Cheers,
Al.
