Have you ever seen these little guys in action? For *years* I’ve wanted to capture this kind of image of mating Mandarinfish. But it’s not easy. For starters, they aren’t very common fish. Then they are difficult to track with a camera because they swim quickly in and out of the coral, flitting back-and-forth in movement akin to that of hummingbirds. And they are quite small, just 4-6cm. Oh, and they are notoriously shy of divers and lights.

The males spend the last hour of dusk courting and chasing the females around, lookin’ for love. When a female is ready to mate, she rests her belly on the male’s pelvic fin. Connected cheek-to-cheek, the pair leave the reef’s protection, and rise up into the water column. At the peak of their ascent, they release their spawn which will quickly disperse with the passing currents. Then the fish dash back down into the coral. The ascent lasts a few seconds, the spawning lasts less than one second. The challenge is guessing when their ascent will peak, and waiting for that moment before pressing the shutter: too soon, and your strobes won’t recycle in time to get another shot; too late, and the tiny fish are gone.

I spent two evenings with the Mandarinfish, and captured a total of just 12 frames. This was the only photo where both fish were positioned facing their bodies towards me during their ascent. And the tiny cloud of spawn is in the frame as well, which was a nice bonus.
