Pictured this week is a macro shot of an Acropora granulosa. This coral is extremely pretty, but there’s an issue with the coral in this picture. Can anyone spot it? I’ll give you a hint, it’s very tiny and is not desirable to have on an Acro coral. Click on the image and then zoom in to get a better look. You should see what I’m talking about. If nobody has guess it correctly in a week, I’ll spill the beans.
