This is of course for everyone, but mostly for Mark and Adam as they seem to like funky invert pics.
This one is hard to see, but underneath the dead coral skeleton, (the branch that is "looking" straight at you,) is a Spiney Oyster. I believe that's what it is anyway. You can see the opening with a white fringe on 2 sides of it. It sticks out about a quarter inch from the shell. You can't see it, but the other side has an opening as well.
This is a closeup of my largest Mexican Turbo Snail. It seems the only thing it really bothers in my tank is a branch of Frogspawn that gets knocked around by him sometimes. It does a great job on the green algae that grows on the glass though.
This thing looks like something coming back from the dead. (Hey, just in time for Halloween...)
"Hey, I'm just hanging upside down cleaning rock."
And this one is especially for Mark. I shifted a rock to move a coral up higher in the tank and guess what I found underneath.
