Red-spotted blenny (Blenniella chrysospilos) pair, just finished spawning. After attracting the female (foreground) to his burrow, the male moves to another hole while the female deposits eggs. He visits multiple times to fertilize while she does this. This is the spit-second just before the female departs and the male takes over to brood the eggs. The male's dark hue is breeding coloration. Kumejima, Okinawa, Japan, Pacific Ocean
