This is a very old camera at the infancy of this colony in my tank. I call this one the birth pic as it is in the process of making another head. I happened to catch the bubble at the right moment.
Taken with an old school Fuji E550 Point and Shoot camera.
Thread cleaned up. If your pic is gone either the link was broken or it was off subject. Check the first post for subject and rules. This month the subject is Euphyllia corals.
