Overview
The black leopard wrasse (Macropharyngodon negrosensis) is a small wrasse of the family Labridae from the Indo-Pacific. Females are blackish with small pale spots, while males are blackish with pale green-edged scales and blackish caudal-fin lobes.
Taxonomy
- Family: Labridae
- Genus: Macropharyngodon
- Scientific name: Macropharyngodon negrosensis
- Described by Herre, 1932
Habitat
The species ranges from the Andaman Sea and Christmas Island to the Philippines and Samoa, north to the Ryukyu Islands and south to northern Australia. It lives on lagoon and seaward reefs with mixed sand and coral substrates.
Tank requirements
- Minimum tank volume: 250 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Maximum size: about 12 cm
- Lifespan: 8-15 years
- Fine sand bed for burying
Diet
Macropharyngodon negrosensis is carnivorous and feeds on small benthic animals picked from the substrate. Like other leopard wrasses it is a delicate feeder best kept in a mature tank with live microfauna.
Compatibility
It is a peaceful, diurnal wrasse of the middle water column, found in pairs or loose groups near the bottom and making distinctive up-and-down movements when threatened. Calm tank mates are recommended.
Reef compatibility
Macropharyngodon negrosensis does not harm corals and is considered reef-safe, although it may consume small benthic invertebrates and the microfauna it depends on for food. Specific gravity 1.024-1.026, carbonate hardness 8-12 dKH.
Conservation status
The IUCN Red List assesses Macropharyngodon negrosensis as Least Concern. Juveniles are dispersed away from breeding ranges by ocean currents.
Macropharyngodon negrosensis (Black Leopard Wrasse) Breeding Guide
Overview
Macropharyngodon negrosensis, the Black Leopard Wrasse, is a labrid of the Eastern Indian Ocean and Western Pacific, recorded from the Andaman Sea and Christmas Island to the Philippines and Samoa, north to the Ryukyu Islands and south to northern Australia. FishBase gives a maximum total length of 12 cm, in lagoon and seaward reefs of mixed sand and coral at 8-32 m, in tropical water of 24-28 °C. FishBase classifies it as oviparous with distinct pairing during breeding.
Sexing
FishBase notes the fish occur in pairs or small loose groups, and that males display a metallic green sheen during courtship. As leopard wrasses are sequential protogynous hermaphrodites, females can transition to males according to social rank, so reliable visual sexing for pairing is not practical at the point of purchase.
Conditioning
The diet consists of small benthic invertebrates picked from the substrate. Maintaining condition depends on a mature reef with an established copepod and amphipod population and frequent small feeds. No conditioning protocol that has produced captive spawning has been published for this species.
Breeding Setup
No aquarium breeding setup exists. The species needs a soft sand bed to sleep in and a well-aged reef supplying live micro-invertebrate food. It occurs naturally in pairs or small groups and spawns over open substrate rather than at a fixed nest.
Spawning Behavior & Trigger
As a labrid, M. negrosensis broadcast-spawns pelagic eggs into the water column with no parental care, and FishBase records distinct pairing during breeding with males assuming bright courtship colour. The triggers are reef-scale environmental cues, not tank parameters, so spontaneous spawning is not expected in captivity.
Egg & Fry Care
Eggs and the resulting larvae are pelagic, drifting in the plankton until settlement. The very small first-feeding larval stages cannot be reared in home aquaria, which is the central reason the species is not captive-bred.
Common Challenges
A demanding live-invertebrate diet, the need for a sand bed and a mature reef, fragility on import, broadcast pelagic spawning and protogynous social biology together make purposeful breeding impractical and even routine husbandry an advanced undertaking.
