I noticed while I was at JL that the corals like yours showing up on my rocks were the same as the symbiotic porites that exist with Christmas tree worms and sure enough, a tonne of them started to pop up recently on my LR as well.
I bet you will notice many of these on your rocks shortly.

No pistol shrimp and no Christmas tree worms so far. I have had the Cuban LR for 2 months now so I suspect I have seen all of the wildlife that I am going to get. Lots of very small feather dusters.
