Paul thanks for the compliments, I had a great time meeting everyone.
I'm glad you figured out the problem with the boat, but what a pain to have to deal with the marina that way, good luck. Now that I'm prepared for the hike to shore I'll know to bring a dry bag for the camera stuff. It would have been nice to get pics of wingo trying to touch the bottom
My observation of the grass shrimp in my reef is that they like to form little groups. I have not observed them eating anything yet, and I don't think any of the fish have tried to eat them. My ocilaris clownfish got very upset they were in her area and kept chasing them away, that was about the only danger the shrimp were ever in.
