Is anyone familiar with what other kinds of creatures one might get on LR? This thing is translucent, it has a smooth swim stroke (or whatever you call it) ie-not jerky, it is narrow, about 3/4 inch long. I've seen it twice now, once swimming away from the sand after I'd done a dip and once today as I was looking at the rock it had swam to. It just kind of regally walked down the edge of the rock (about 1-2 inches of cat-walk) untill it went to the other side. Right after I saw him I heard my clicking creature from what sounded like the other side of the tank. Any ideas?
