Quick Answer
The Leopard Wrasse is a expert-level saltwater fish needing at least a 55-gallon tank, 72-78°F water, and pH 8.1-8.4. Leopard Wrasses demand precise water conditions and are best kept by experienced aquarists.
Leopard Wrasse Overview
The Leopard Wrasse (Macropharyngodon meleagris) is a challenging but stunning species for experienced aquarists only, native to Indo-Pacific. As a saltwater carnivore, this species has earned its place as a staple in reef aquariums and FOWLR (fish-only with live rock) setups worldwide. The Leopard Wrasse is a peaceful species that generally coexists well with other non-aggressive fish. With proper care and appropriate water conditions, Leopard Wrasses can live for several years and become a rewarding centerpiece — or supporting cast — of your aquarium.
According to FishBase's species profile, the Macropharyngodon meleagris is widely distributed across Indo-Pacific and has been selectively bred in captivity for decades, resulting in a robust trade fish that typically adapts well to aquarium conditions. That said, replicating natural water parameters as closely as possible always produces the healthiest fish.
Tank Requirements
The Leopard Wrasse requires a 55-gallon tank as a minimum — larger is always better. Crowding this species into too-small quarters leads to stress, aggression, and disease — the most common cause of failure with this fish. Budget for a canister filter with adequate flow — target 4–6× tank volume per hour to keep the water clean and well-oxygenated.
- Minimum Tank Size: 55 gallons
- Temperature: 72-78°F (ideal: ~75°F)
- pH: 8.1-8.4 To maintain higher pH, use crushed coral substrate or aragonite sand. Regular water changes help stabilize pH.
- Filtration: A canister filter with adequate flow — target 4–6× tank volume per hour
Live rock provides essential biological filtration and hiding spaces in saltwater setups. Maintain salinity at 1.023–1.025 specific gravity and ensure adequate protein skimming. Once your tank is fully cycled, perform 20–30% water changes weekly to maintain stable parameters. Stability matters more than hitting exact numbers — sudden swings cause far more harm than gradual drift.
Diet & Feeding
In the wild, Leopard Wrasses are predators that hunt live prey. In captivity, replicate this with high-protein foods. High-quality carnivore pellets, frozen bloodworms, frozen brine shrimp, mysis shrimp, and occasional live foods are all excellent choices for this species.
Feed once or twice daily, offering only what they can consume in 2–3 minutes. Remove uneaten food promptly. Variety is key — rotate between different protein sources to prevent nutritional deficiencies.
Compatibility & Tank Mates
The Leopard Wrasse has a peaceful temperament and does well in community aquariums with similarly sized, non-aggressive fish.
Good tank mate options from our database include Anthias (Lyretail), Bangaii Cardinalfish, and Bi-Color Blenny. Avoid housing Leopard Wrasses with highly aggressive species or fish that compete for the same territory.
Common Health Issues
The Leopard Wrasse is susceptible to disease when conditions are suboptimal, but no aquarium fish is immune to illness. Prevention through clean water and a varied diet is always better than treatment. For detailed species-specific health notes, SeriouslyFish has an excellent care sheet for the Leopard Wrasse.
Marine Ich (Cryptocaryon)
White spots similar to freshwater ich but caused by a different parasite. Treat in a separate quarantine tank with copper medication or hyposalinity. Never treat in a reef tank.
Marine Velvet (Amyloodinium)
More aggressive than marine ich, causing rapid breathing and golden shimmer. Requires immediate copper treatment in quarantine — mortality is high without quick action.
Brooklynella
A ciliated parasite causing mucus buildup and rapid gill damage. Common stress-related disease. Treat with formalin-based medication in a hospital tank.

Frequently Asked Questions
What size tank does a Leopard Wrasse need?
The Leopard Wrasse requires a minimum of 55 gallons. Smaller tanks cause stress, reduce lifespan, and increase disease susceptibility. If you can afford a larger tank, always go bigger — fish generally thrive with extra space.
What do Leopard Wrasses eat?
The Leopard Wrasse is a carnivore. Feed high-protein foods: frozen bloodworms, mysis shrimp, carnivore pellets, and occasional live foods. Feed once or twice daily, only what they can eat in 2–3 minutes.
What water temperature and pH does the Leopard Wrasse need?
Maintain water temperature between 72-78°F and pH between 8.1-8.4. Use a reliable aquarium thermometer and test your water weekly. Stability is more important than hitting exact numbers — sudden parameter swings are more dangerous than gradual drift.
What fish can live with a Leopard Wrasse?
The Leopard Wrasse can coexist with Anthias (Lyretail), Bangaii Cardinalfish, Bi-Color Blenny, among others with similar temperament and water requirements. Avoid pairing with aggressive fin-nippers or much larger predators.
Is the Leopard Wrasse hard to keep?
Yes — the Leopard Wrasse is considered an expert-level fish requiring precise water chemistry, specialized diet, and extensive tank space. It is not recommended for beginners. Research thoroughly before purchasing, and never buy on impulse.
