Mandarinfish

Synchiropus splendidus

Mandarinfish are tiny, brilliantly-coloured dragonets that spend the day hidden in rubble and emerge at dusk for a short, ritualised mating display — pairs rising a foot off the bottom together and releasing gametes. The dive is a sit-and-wait in the last ten minutes of light, hovering over the correct rubble patch. Lembeh, Mabul, Palau, and Dauin in the Philippines all have well-known mandarin dive sites. Red filters and restrained strobe work preserve the behaviour for subsequent divers.
