Broomtail Wrasse

The Broomtail Wrasse is a large, powerful saltwater fish with a commanding presence and highly distinctive adult coloration. Juveniles are typically more subdued, while adults develop rich green, blue, and reddish tones, bold facial markings, thick lips, and the broad, brush-like tail that gives the species its common name. Reaching roughly 20 inches at maximum adult size, this is a substantial marine aquarium fish best reserved for large, carefully planned systems.

Cheilinus lunulatus is native to the western Indian Ocean, with a natural range extending from the Red Sea to the Gulf of Oman. In the wild, adults inhabit coral reefs and adjacent rubble, sand, and seagrass areas, particularly along reef slopes and edges. They are active predators that feed heavily on hard-shelled invertebrates, especially mollusks, using their strong jaws to investigate and crush prey.

Because of its adult size, feeding behavior, and predatory nature, the Broomtail Wrasse is better suited to large fish-only aquariums or carefully selected predator systems than traditional reef aquariums. It is an impressive centerpiece species, but long-term housing should be planned around its considerable size and appetite.

Tank Requirements

The Broomtail Wrasse requires a very large aquarium with substantial swimming room and durable rockwork arranged into caves, overhangs, and sheltered retreat areas. Because adults can approach 20 inches in length, long-term housing should emphasize open swimming space rather than densely packed aquascaping.

Rock structures should be stable and securely positioned, as a large wrasse can disturb loosely stacked rock while searching for food. A sand or mixed substrate can be used, particularly when creating a natural reef-edge environment, although this species primarily shelters around rockwork rather than depending on deep sand for burial.

Strong biological filtration, efficient protein skimming, and consistent maintenance are important because large carnivorous wrasses can place a significant nutrient load on the aquarium. A secure lid is also recommended, especially for newly introduced or startled specimens.

Diet and Feeding

The Broomtail Wrasse is a carnivore that naturally feeds primarily on hard-shelled invertebrates, including mollusks and other benthic prey.

In captivity, provide a varied marine-based diet consisting of chopped shrimp, clam, mussel, squid, krill, scallop, marine fish flesh, and quality frozen carnivore preparations. Larger marine pellets may also be accepted once the fish becomes established.

Juveniles can be fed smaller portions once or twice daily, while larger adults should receive appropriately sized meals based on body condition and activity level. Avoid relying on a single food source, and vary the diet to provide balanced marine nutrition.

Temperament and Tankmates

The Broomtail Wrasse is generally confident, assertive, and predatory. Smaller fish and mobile invertebrates may be viewed as food, particularly as the wrasse reaches adult size.

Suitable tankmates should be large enough to avoid predation and robust enough to coexist with an active wrasse. Large angelfish, tangs, triggers, groupers, and other appropriately sized marine fish may be compatible when adequate space is available.

Avoid housing it with very small, timid, or delicate species. It is generally best kept as a single Broomtail Wrasse unless the aquarium is exceptionally large and the aquarist has experience managing large wrasse interactions.

Reef Compatibility

The Broomtail Wrasse is not considered reef safe.

While it may not deliberately consume coral tissue, its natural diet includes mollusks and other hard-shelled invertebrates. Ornamental shrimp, crabs, snails, clams, and similar reef inhabitants are at significant risk of predation.

Its large adult size and powerful feeding behavior can also make it disruptive in delicate reef aquascapes. This species is therefore much better suited to a large fish-only or fish-only-with-live-rock aquarium.

Water Parameters

Temperature: 75–80°F
Specific Gravity: 1.024–1.026
pH: 8.1–8.4
Alkalinity: 8–12 dKH

Stable water conditions, good oxygenation, and strong filtration are especially important for large specimens. Maintaining consistent salinity and water quality is more beneficial than continually adjusting parameters toward one exact value.

Common Considerations

• Large adult size: This species can reach approximately 20 inches and requires substantial long-term swimming space.
• Predatory feeding behavior: Shrimp, crabs, snails, clams, and other mobile or hard-shelled invertebrates may be consumed.
• Heavy bioload: Large individuals require strong filtration and regular aquarium maintenance.
• Tankmate size matters: Small fish may eventually be viewed as prey and should not be considered safe companions.
• Long-term planning is essential: Juveniles can grow into powerful adults, so the aquarium should be selected with mature size and behavior in mind.
