This species of fish (Eastern Blue Groper) is known as being very friendly with divers and snorkellers, but today I found this guy to be more friendly than normal. He was trying to rub me on our dive at Bare Island. Then of course I noticed why. The poor guy was covered in sea lice - they were scurrying all around his face and there were a couple of marks that looked suspiciously like burrows. It must have been causing the fish some discomfort, if only itchiness which explains why he wanted to rub me.
Weedy Seadragons eat sea lice. In Bare Island there are a couple of weedy seadragons so I am hoping he soon makes friends with one of them so that the pipefish has a good meal and the groper is relieved of his discomfort.
