Overview
The vermiculate or divided leopard wrasse (Macropharyngodon bipartitus) is a small wrasse of the family Labridae from the western Indian Ocean. It shows a reticulated red-and-white pattern and reaches a maximum length of about 13 cm.
Taxonomy
- Family: Labridae
- Genus: Macropharyngodon
- Scientific name: Macropharyngodon bipartitus
- Described by J. L. B. Smith, 1957
Habitat
The species ranges through the western Indian Ocean, from Zanzibar, Mozambique, the Seychelles, Reunion, Mauritius and South Africa to the Chagos Archipelago, southern Oman, Rodrigues and Yemen. It is marine and reef-associated, inhabiting lagoon and sheltered seaward reefs at depths down to about 30 m, in waters of roughly 25 to 29 °C.
Tank requirements
- Minimum tank volume: 250 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Maximum size: about 13 cm
- Lifespan: 8-15 years
- Fine sand bed for nightly burying
Diet
Macropharyngodon bipartitus is carnivorous and feeds by picking small invertebrates from the substrate. It is a delicate feeder, and a mature system with abundant live microfauna helps it acclimate.
Compatibility
It is a peaceful, diurnal wrasse that swims in the middle column and burrows in the sand at the sign of danger. The species occurs singly or in pairs, with females often forming small groups, and it suits calm tank mates.
Reef compatibility
Macropharyngodon bipartitus does not harm corals and is regarded as reef-safe, though it may consume small benthic invertebrates and beneficial microfauna it relies on for food. Specific gravity 1.024-1.026, carbonate hardness 8-12 dKH.
Conservation status
The IUCN Red List assesses Macropharyngodon bipartitus as Least Concern. It is harvested for the aquarium trade and is of no fisheries interest.
Macropharyngodon bipartitus (Vermiculate Leopard Wrasse) Breeding Guide
Overview
Macropharyngodon bipartitus, the Vermiculate Leopard Wrasse, is a small labrid of the Western Indian Ocean, recorded from Zanzibar and Mozambique to the Seychelles, Maldives, Chagos, southern Oman and South Africa. FishBase gives a maximum total length of 13 cm, in lagoon and sheltered seaward reefs to about 30 m. It feeds by picking invertebrates from the substratum and burrows in the sand at the sign of danger. FishBase classifies it as oviparous with distinct pairing during breeding.
Sexing
Reef Builders notes that all leopard wrasses are sequential protogynous hermaphrodites, capable of changing into males when the social structure allows. The most effective way to keep them is in a haremic group of one male with several females. Because functional sex follows social rank, fixed pairs cannot be reliably selected at purchase.
Conditioning
These fish feed continuously on small benthic invertebrates picked from the substrate. Sustaining them depends on a mature reef with an established population of copepods and amphipods, supplemented by frequent small meals, especially immediately after collection. No conditioning protocol leading to captive spawning has been published.
Breeding Setup
No aquarium breeding setup exists for this species. It needs a deep, soft sand bed to bury into for shelter and overnight rest, and a well-aged reef rich in live micro-invertebrate food. Reef Builders recommends a haremic structure, but this supports husbandry, not deliberate reproduction.
Spawning Behavior & Trigger
As a labrid, M. bipartitus 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 and feeding in the plankton until settlement. The very small first-feeding larval stages of these wrasses cannot be reared in home aquaria, which is the central reason the species is not captive-bred.
Common Challenges
The species combines a demanding diet of live micro-invertebrates, a strict sand-burrowing requirement, fragility on import, broadcast pelagic spawning and protogynous social biology. These factors make purposeful breeding impractical and place even basic husbandry firmly in the advanced category.
