Watching mating mandarin fish is always great during a dive. Close to the lodge, there is a spot where they live. They are only maximum 6 cms long, and do come out of the rubble at dawn. It means a night dive. Packed with all gear (camera, torch, and all other nice accessories), we set-off at 17:30. Just in time in the water to see them mating. And that is definitely what they do a lot before full darkness.
