Mandarinfish

Ambon Bay has established dusk sites for mandarinfish mating, run as scheduled sunset dives rather than chance encounters. Resident year-round; the timing is tied to dusk, not the calendar.

Seen on dusk dives on the rubble and jetty pilings off Banda Neira. It is a time-of-day sighting rather than a seasonal one — you need to be in the water in the last half hour of light.

Mandarinfish are reported around the shallow East Tangat gunboat, typically at dusk in the coral and debris. Resident but shy and site-specific.

Resident in rubble and jetty structures; best seen at dusk when they rise to mate.

Resident in the rubble at Kapalai's Mandarin Valley and at several Mabul sites. Only reliably seen in the short window around dusk when they rise to mate, so it has to be booked as a specific dusk dive.

Resident, with reliable dusk courtship at Lighthouse.

Reliable at set spots on the Panagsama house reef at dusk, when the males display; a guide is usually needed to find them.

Reliably seen at dusk on shallow, calm sites such as The Hill and around Sabang, when they emerge to mate. A dedicated dusk dive is usually needed.

Resident year-round; sightings depend on being in the water shortly before sunset, not on season. Best near mangrove-channel rubble at sites like Yenbuba and Sauwandarek jetties.

Resident at Mabul with dusk courtship; Mabul is not subject to the November Sipadan closure.

Present on the Padre Burgos shoreline reefs; as everywhere, seen on dusk dives when they rise out of the rubble to spawn.

Present in sheltered coral rubble and staghorn patches; most reliably seen on dusk dives when they rise to mate.

Present in shallow rubble and coral patches at some sites, most reliably on dusk dives when they emerge to mate.

Mandarinfish are a dusk-dive target on selected central reefs, not a general daytime sighting.
