I commented that I have some hitchhiker coral growing on the back-side of a rock. Well, I finally got my hands wet and turned the rock around and got the camera out. What I have here is a small colony of Zoanthids. These are really small and it turned out to be difficult to photograph. I took about 25 pictures before I got one that was good enough to post.I also have a few white sponges that hitchiked their way into my tank. Here is a picture of one of them I took today. My green bubble-tip anemone is in the lower-right of the picture. Some other green Zoanthids that I purchased are in the upper-left.
Here is a picture of the same sponge taken on January 12th.
My, how it has grown.
