A stunning wrasse covered in a leopard-like mosaic of spots, prized for its beauty but notoriously difficult to establish because it is a specialized micro-predator that often refuses prepared food. Best suited to mature, pod-rich reef systems and experienced keepers.

Part of the Wrasses
Wrasses (family Labridae) are an enormous, diverse group of active, colorful reef fish ranging from tiny fairy and flasher wrasses to large predators. Many sand-diving species sleep buried in the substrate, most are accomplished jumpers, and several are prized for controlling pest invertebrates in reef aquariums.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Mature sand-bed reef
55 gal / 200 L mature reef
Macropharyngodon meleagris is a sand-sleeper — it buries every night, so a deep (5+ cm) fine sand bed is mandatory. Needs a mature reef with abundant copepods/amphipods; quarantine carefully.

Recommended
Pod-rich reef with refugium
75–90 gal / 280–340 L
Larger pod-producing refugium supplies natural prey. Add live rock with calm grazing zones and supplement with frozen mysis. Peaceful — house only with non-aggressive tankmates.

Ideal
Large lagoon reef
125 gal+ / 470 L+ lagoon
Wide footprint with deep sand, dense rock, and a thriving pod population. Possible harem (one male, multiple females) becomes practical at this size and brings out full colour.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Fish eggs are small, translucent spheres, often laid in clutches on plants, substrate, or in a nest — or carried/brooded by a parent in livebearing and mouth-brooding species. A dark eye spot and the curled embryo become visible inside as development progresses.

Fry
Newly hatched fry are tiny and semi-transparent, frequently still carrying a yolk sac that fuels them before they feed freely. They lack full fin structure and adult coloration, staying near cover until they can swim and forage on their own.

Juvenile
Juveniles look like miniature adults but with developing fins and muted or different markings; many species shift pattern and color as they mature. Growth is rapid at this stage given clean water and steady feeding.
Adult
Adults show the species' full size, finnage, and mature coloration, and are sexually mature. Many fish develop sex-specific differences in size, color, or fin shape, which can intensify during breeding.
Habitat & enclosure
Provide a minimum of 50 gallons of mature, well-established reef with a deep, fine sand bed and abundant live rock teeming with copepods and amphipods, because the leopard wrasse depends heavily on natural microfauna. The deep sand bed is non-negotiable, as the fish dives into the sand to sleep every night and to hide when threatened. A secure, gap-free lid is essential.
Maintain stable tropical reef parameters: temperature 72-82 F (22-28 C), pH 8.1-8.4, salinity 1.023-1.026 specific gravity, and moderate flow. Stable, pristine water and a thriving pod population are critical to long-term survival.
Substrate
A deep bed of soft, fine sand (at least 1.5-2 in / 4-5 cm) is mandatory; the leopard wrasse buries completely every night and when alarmed, and coarse or shallow substrate will injure or stress it. Pair with mature, pod-rich live rock for grazing.
Equipment & setup
Run a mature marine system with a protein skimmer, strong biological filtration, a reliable heater, and ideally a refugium to continuously culture copepods. Provide moderate flow and standard reef lighting, and fit a secure, gap-free lid to prevent jumping.
Diet
A specialized micro-carnivore that grazes the sand and rock for tiny invertebrates: copepods, amphipods, small snails, foraminifera, and other meiofauna. This narrow diet is the main reason it is rated advanced, as many individuals slowly waste away if the tank cannot supply enough live prey or if the fish never learns to take prepared foods.
Keep it only in a mature reef with a strong pod population, ideally supported by a refugium. Tempt it onto frozen cyclops, mysis, and live blackworms or brine, and feed small amounts several times daily. Always buy a plump specimen seen eating, never a thin one.
Behavior & temperament
Peaceful, reef-safe, and harmless to corals, the leopard wrasse spends its day methodically picking over rock and sand. It is gentle and easily outcompeted, so it must be kept with calm, non-aggressive tankmates and should never share a tank with fast, greedy feeders that will starve it out.
Keep one per tank, or a male with females in a large, mature system. It generally ignores ornamental shrimp but may pick at very small snails. Its delicate temperament means stocking order and a stress-free environment are as important as diet.
Health
Establishment is the hardest hurdle: many leopard wrasses arrive thin and starve within weeks, so success hinges on buying a healthy, feeding individual and providing abundant natural microfauna. They are also prone to stress on arrival and may stay buried in the sand for a day or more after shipping, which is normal.
They are susceptible to ich and velvet and can be sensitive to copper, so quarantine thoughtfully, ideally in a system with a sand bed. A deep, fine sand bed is essential to prevent abrasion and chronic stress from being unable to bury.
Tips, DIY & hacks
Only buy a leopard wrasse that you have watched eat and that has a full, rounded belly, and add it to an established, peaceful, pod-rich reef. Maintain a refugium and consider pod-dosing to sustain it. Provide the deep sand bed before introduction, drip-acclimate slowly, and quarantine carefully in a sand-bottomed system.
