The Lunare Wrasse (Thalassoma lunare), also known as the Moon Wrasse or Lyretail Wrasse, is a brilliantly colored and highly active marine wrasse native to the Indo-Pacific. Adults display an impressive combination of green to blue coloration, reddish to purplish vertical markings, colorful facial bands, and a distinctive yellow crescent-shaped tail. FishBase specifically notes the yellow lunate tail as an identifying feature of adults.

The species has an exceptionally broad natural distribution, occurring from the Red Sea and East Africa across the Indo-Pacific to the Line Islands, north to southern Japan, and south to Lord Howe Island and northern New Zealand. It inhabits lagoon and coastal reefs as well as protected seaward reefs, typically at depths of approximately 1–20 meters.

Lunare Wrasses are energetic, powerful swimmers that spend much of the day exploring rockwork and searching for food. In nature, their diet consists primarily of small benthic invertebrates and fish eggs. This natural predatory behavior makes them unsuitable for aquariums containing ornamental shrimp, small crabs, and other vulnerable invertebrates.

This specimen is wild collected from Indonesia and is one of Dr. Mac's Quarantined and Conditioned Fish. Because this is an active species that can become assertive as it matures, it is best maintained in a spacious aquarium with appropriately sized tankmates.

Aquarium Requirements: Lunare Wrasses are very active swimmers and need substantial open swimming space combined with rockwork for shelter and exploration. A secure, tightly fitted aquarium cover is important, as wrasses are capable jumpers. Aquarium-care references commonly recommend tanks of at least 125 gallons for this species.

Temperament: This is not a timid community wrasse. It can become increasingly assertive as it grows and may harass smaller, passive fishes or other wrasses. Tankmates should be selected with its adult size and activity level in mind.

Reef Compatibility: The Lunare Wrasse should not be classified as reef safe with invertebrates. Its natural diet includes benthic invertebrates, and aquarium specimens may prey upon ornamental shrimp, crabs, snails, and other small invertebrates.

Diet and Feeding: Offer a varied carnivorous diet including mysis shrimp, krill, chopped shrimp, clam, squid, and other appropriately sized marine meats, along with quality carnivore pellets or frozen marine preparations. FishBase reports that wild T. lunare feeds primarily on small benthic invertebrates and fish eggs.

and inspected

step-2_400b411d-17ae-4476-b2bf-ca4214bf3432

We proactively treat fish during conditioning rather than simply holding them

step-3

Fish are closely monitored for feeding response, behavior and overall health.

step-4

Fish are transitioned onto prepared foods and conditioned for aquarium life.

Order FAQs  

About Our Facility

Q: Are your corals aquacultured?
A: Yes. Many of our corals are grown in our Maryland Certified & Licensed Coral Aquaculture Facility.

Q: Why choose aquacultured corals?
A: Aquacultured corals are:
- More sustainable
- Better adapted to aquarium life
- Typically hardier than wild specimens

Q: Who selects and grows your corals?
A: Our corals are grown and curated by Dr. Mac a Board Certified Veterinary Pathologist with decades of hands-on reef experience.

Ordering & Shipping

Q: What does WYSIWYG mean?
A: “What You See Is What You Get.” The exact coral shown in the photo is the one you will receive.

Q: Can I request a specific color or variation?
A: For WYSIWYG items, what’s pictured is what you get. For non-WYSIWYG items, we do our best to match color and size, but natural variation occurs.

Q: Can I combine multiple orders to save on shipping?
A: Yes—contact us before shipping and we’ll consolidate when possible.

Q: How are corals and fish shipped safely?
A: We use insulated boxes, temperature control (heat/cold packs), and overnight delivery to ensure safe arrival.

Q: What days do you ship?
A: Typically Monday–Wednesday to avoid weekend delays.

Q: Do I need to be home for delivery?
A: Yes—someone should be available to receive livestock immediately.

Q: What if my coral or fish arrives dead (DOA)?
A: Contact us within a specified timeframe (e.g., 2 hours) with clear photos, and we will resolve it quickly.

Q: What voids the guarantee?
A: Missed deliveries, improper acclimation, or delays beyond our control.

Live Arrival Guarantee

Q: What if my coral or fish arrives dead (DOA)?
A: Contact us within a specified timeframe (e.g., 2 hours) with clear photos, and we will resolve it quickly.

Q: What voids the guarantee?
A: Missed deliveries, improper acclimation, or delays beyond our control.

Acclimation & First 24 Hours

Q: How do I acclimate new livestock?
A: Float to match temperature, then drip acclimate before placing in tank.

Q: Should I dip corals before adding them?
A: Yes but be careful, coral dips help prevent pests but use caution. Certain corals might benefit from a short quarantine period instead of a dip so as to further stressing them.

Q: Why does my coral look closed or stressed?
A: This is normal after shipping—most corals open within 24–72 hours.

Aquarium Setup & Compatibility

Q: Where should I place my coral in the tank?
A: Placement depends on the coral type (LPS, SPS, soft). Lighting and flow requirements vary—check each product description.

Q: Can different corals touch each other?
A: Many corals have sweeper tentacles and can sting neighbors. Always allow space.

Q: How fast will my coral grow?
A: Growth depends on species, lighting, water quality, and feeding.
