Spotted Wrasse (Anampses meleagrides) saltwater aquarium fish

Overview:

The Yellowtail Wrasse (or commonly the Spotted Wrasse) is an active, hardy marine wrasse that grows into a large, powerful fish and is best suited to experienced aquarists with spacious systems. Juveniles are often strikingly patterned, but adults become much larger and more robust, so long-term planning is essential. Provide a large, tightly covered aquarium with abundant swimming room, ample live rock for grazing and shelter, and a deep sand bed or sandy areas for burrowing. This species is known to sleep in the sand and may jump when startled, so a secure lid is mandatory. Stable reef-quality water is important: temperature 24–27°C, salinity 1.023–1.026, pH 8.1–8.4, and low ammonia/nitrite with minimal nitrate. Strong filtration and regular water changes help support its high metabolism and messy feeding habits.

Diet and Feeding:

Yellowtail Wrasses are carnivorous and should be fed a varied, protein-rich marine diet. Offer a mix of frozen mysis shrimp, chopped seafood, krill, squid, clams, and high-quality marine pellets or fortified frozen preparations. Younger fish usually eat more frequently; adults typically do well with 1–2 feedings daily, adjusted to avoid overfeeding. Because they are active hunters, they may spend much of the day foraging, so multiple small meals are often better than one large feeding. Enrich foods with vitamin supplements and occasional fatty acid boosters to support coloration, immune health, and recovery from stress. Avoid relying on feeder fish, which can introduce disease and poor nutrition. In mixed reef systems, ensure the wrasse receives enough food so it does not become aggressive toward smaller tankmates while hunting.

Compatibility:

This species is generally semi-aggressive and becomes more assertive with age. It is best housed with similarly sized, robust tankmates such as tangs, angelfish, triggers (in appropriate non-reef setups), puffers, and larger wrasses. Avoid very small, slow, timid fish, ornamental shrimp, crabs, snails, and other crustaceans, as Yellowtail Wrasses may prey on them. It can also bully passive species or compete heavily for food. In reef aquariums, compatibility is mixed: it may be reef-safe with caution, but decorative shrimp and small invertebrates are at risk. Keep only one adult unless the system is very large and carefully managed, as territorial behavior can develop. Introducing the wrasse last often reduces aggression.

Health and Quarantine:

Quarantine is strongly recommended for 4–6 weeks in a bare-bottom or lightly furnished tank with sand available for sleeping. This helps detect marine ich, flukes, bacterial infections, and parasitic issues before the fish enters the display. Yellowtail Wrasses are generally hardy once settled, but they are prone to stress from transport, poor water quality, and inadequate nutrition. Watch for rapid breathing, flashing, loss of appetite, or abnormal hiding. Because they bury themselves in sand, avoid unnecessary disturbance and use gentle acclimation. Maintain excellent oxygenation and water quality, and feed varied foods to prevent nutritional deficiencies. Early quarantine treatment and observation are the best preventive care for long-term success.

Yellowtail Wrasses are highly active, fast-swimming fish that spend much of the day patrolling the water column and foraging through rockwork, so they require ample open space with some secure hiding areas and a tight-fitting lid. They are generally semi-aggressive to territorial, especially as adults, and conspecifics are often challenged unless the fish are a proven pair or introduced carefully in a very large system. A minimum tank size of 125 gallons is recommended, with abundant live rock, caves, and visual barriers to break sightlines and reduce chasing. In the right setup they can coexist with robust reef-safe species, but they may harass timid tank mates and are best kept with similarly active, confident companions. Their diet is carnivorous to opportunistically omnivorous, centered on small crustaceans, worms, mollusks, and other benthic invertebrates they hunt throughout the day. They should be offered a varied diet of meaty frozen foods, enriched seafood, and quality prepared fare to maintain condition and behavior.

FAQ

Frequently Asked Questions

About the Spotted Wrasse

  • Is the Yellowtail Wrasse really reef safe, and will it eat my ornamental shrimp, snails, or copepods?
    The Yellowtail Wrasse is considered one of the safer wrasses for reef tanks, but it is not 100% guaranteed with every invertebrate. It usually leaves corals alone and is generally fine with snails and larger decorative shrimp, but very small shrimp, tiny crabs, worms, and microfauna can be at risk, especially in a new or underfed tank. It is also an active pod hunter and will significantly reduce copepod populations over time, though it usually won’t wipe them out as fast as some other wrasses.
  • Does a Yellowtail Wrasse need a sand bed, and what happens if I keep one in a bare-bottom tank?
    Yes, it strongly prefers a sand bed because it is a sand-sleeping wrasse. At night and when stressed, it will dive into sand to sleep or hide. In a bare-bottom tank, it can become stressed, fail to settle properly, injure itself trying to bury, or eventually perish from chronic stress. A fine sand bed of at least 1–2 inches is ideal, and the tank should have a secure lid because it can also jump.
  • How large of a tank does a Yellowtail Wrasse actually need, and can it be kept with other wrasses?
    A single Yellowtail Wrasse is best kept in a tank of at least 75 gallons, with 90+ gallons being better if you want stable space and room for swimming. It is active but not overly large, reaching about 4–5 inches. It can be kept with other wrasses, but compatibility depends on species, tank size, and introduction order. In smaller tanks, it may become territorial toward similar-shaped or similarly colored wrasses, especially other Halichoeres species. More space and adding it after more passive fish usually helps.
  • What should I feed a Yellowtail Wrasse to keep its color and health up, and how often should it eat?
    It should be fed a varied carnivorous diet multiple times a day if possible, especially when newly acquired. Best foods include frozen mysis, chopped shrimp, krill, enriched brine shrimp, finely chopped seafood, and high-quality carnivore pellets or small sinking foods if it accepts them. Frequent small feedings help keep body condition, coloration, and activity levels strong. This species is an enthusiastic feeder once settled, and underfeeding often leads to fading color, reduced activity, and increased interest in tankmates’ small invertebrates.
  • Why did my Yellowtail Wrasse disappear into the sand or stop eating after being added to the tank?
    This is very common behavior. Yellowtail Wrasses often bury themselves when first introduced, when lights are intense, or when they feel threatened. They may stay hidden for a day or several days before emerging and eating. If it is breathing normally and there are no signs of injury or harassment, this is usually part of acclimation. A longer acclimation, dim lighting, minimal disturbance, and a secure sand bed help. If it remains buried far longer than expected, comes out but refuses food, or shows rapid breathing, then water quality, bullying, transport stress, or disease should be investigated.
