Whats this on my Clam?

That's a resting Nudibranch. They are almost all very colorful, but can sometimes be trouble. Keep an eye on it. If it starts to bother something you want to keep then... hmmm, which one to remove?  Enjoy the diversity of the reef.

The Nudibranchs below, called the Balloon Nudibranch and the Spanish Dancer, were amazing but for lack of food, would not have lasted much longer in my tank so after a few months were returned to where they were collected, Lapahoehoe Point.
