From time to time, my fish seem to want the spotlight. I was about to shoot a cerrtain coral and this gal (yes, it's a female Lyretail anthias) decided to swim into the frame. Fine, if you want to block my efforts, I'll just shoot you instead. Ended up with a really great shot.
Shooting a few shots with my macro lens yesterday, I spotted an oddity on a branch of the staghorn coral and focused on that area momentarily. It looks like a SPS polyp captured a small piece of a LPS hammer's tip that came off somehow. It's about the right size and shape.
