Choat's Leopard Wrasse Care Guide
Macropharyngodon choati is an eastern Australian leopard wrasse with orange blotches; it browses gastropods and foraminiferans and is a delicate feeder.
Compiled by Aquairi from published sources · Published · Updated
Overview
Choat's leopard wrasse (Macropharyngodon choati) is a wrasse of the family Labridae from eastern Australia. Adults bear irregular rows of orange blotches and a black, yellow-edged spot on the operculum. The species grows to about 11 cm.
Taxonomy
- Family: Labridae
- Genus: Macropharyngodon
- Scientific name: Macropharyngodon choati
- Described by Randall, 1978
Habitat
The species is known from eastern Australia, Middleton and Elizabeth Reefs and New Caledonia, and is common on the southern Great Barrier Reef. It occurs in channels and seaward reefs over mixed sand, rubble and coral, to depths of about 30 m.
Tank requirements
- Minimum tank volume: 300 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Maximum size: about 11 cm
- Lifespan: 8-15 years
- Fine sand bed for burying
Diet
It is carnivorous and is usually seen browsing among the substrate for gastropods and foraminiferans, as well as small invertebrates, crustaceans and snails. Like other leopard wrasses it is a delicate feeder.
Compatibility
Choat's leopard wrasse is a peaceful, diurnal wrasse of the middle column. Adults are usually solitary, though juveniles sometimes school with other juvenile wrasses; calm tank mates and a sand bed are recommended.
Reef compatibility
Macropharyngodon choati does not harm corals and is considered reef-safe, although it grazes small benthic invertebrates and microfauna it relies on for food. Specific gravity 1.024-1.026, carbonate hardness 8-12 dKH.
Conservation status
Macropharyngodon choati is an Australian-region species that appears in the marine aquarium trade. It is documented by the Australian Museum and reef monitoring surveys.
Macropharyngodon choati (Choat's Leopard Wrasse) Breeding Guide
Overview
Macropharyngodon choati, Choat's Leopard Wrasse, is a labrid endemic to the Western Pacific waters of Australia. FishBase records it from channels and seaward reefs, usually at 0-30 m, in subtropical water of 23-26 °C. Its body is whitish with orange blotches and bands and a black, yellow-edged spot on the opercle. FishBase classifies it as oviparous with distinct pairing during breeding.
Sexing
As a leopard wrasse, the species is a sequential protogynous hermaphrodite in which females can transition to males according to social rank. Reef Builders recommends keeping leopard wrasses in haremic groups of one male with several females. Reliable visual sexing for pairing is therefore not practical at purchase.
Conditioning
Leopard wrasses graze continuously on micro and macro invertebrate fauna in the substrate. Reef Builders notes the captive environment best suited to them is a mature, well-established reef, not a fish-only system. M. choati is among the hardest to feed successfully on import, and no conditioning protocol leading to captive spawning has been published.
Breeding Setup
No aquarium breeding setup exists. The species needs a soft sand bed to seek refuge in at nightfall and a well-aged reef rich in live food. Given its notoriously low survival rate in captivity, establishing a stable group is itself the limiting step, well before any reproductive attempt.
Spawning Behavior & Trigger
As a labrid, M. choati broadcast-spawns pelagic eggs into the water column with no parental care, and FishBase records distinct pairing during breeding. The triggers are reef-scale environmental cues rather than 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
Choat's Leopard Wrasse combines exceptionally low import survival, a strict requirement for a mature reef with live micro-invertebrate food and a sand bed, broadcast pelagic spawning and protogynous social biology. These factors make purposeful breeding impractical and reserve the species for the most experienced aquarists.
