Here are some shots of three interesting anemones that were hitchikers on the LR. Each is about 6" in diametre.
In this last shot you can see just a bit of my green carpet anemone, which is now about 18" diametre. It has grown remarkably since moving into the new tank. I think it gets a LOT more food than it used to.
