Orange Ball Anemone
Another tiny and virtually undetectable creature is the Orange Ball Anemone. It is actually from the mushroom family, and not an anemone at all. However, due to its appearance, it was named accordingly. I have found these scattered throughout my tank, usually closed up all day long but opened up at night when the lights are out. This particular one was tucked in between some zoanthids that happened to be closed. It's kind of neat looking, and it would be nice if they were larger so they could be enjoyed properly. Reef-safe.
