I haven't even looked at the instructions for the camera yet... still a lot of work to do with it.
I need to get the tripod out, too.
The sun coral is pretty big. I don't think it has added many new polyps since I got it, but it seems to be healthy. There's some kind of macroalgae on its rock that I'm trying to get rid of. You can see it fully extended in the bottom right of the last pic.
