Lyretail Hawkfish (Cyprinocirrhites Polyactis) saltwater aquarium fish

Overview:

The Lyretail Hawkfish (Neocirrhites armatus) is a hardy, active marine fish best kept by experienced aquarists who can provide a stable reef environment and carefully chosen tankmates. Despite its small size, it is territorial and perches openly on rockwork, so it needs plenty of live rock, caves, and elevated vantage points. A tank of at least 30 gallons is recommended for a single specimen, with larger systems preferred if housed with other fish. Water quality should be excellent and stable: temperature 72–78°F, salinity 1.023–1.026, pH 8.1–8.4, and low nitrate. Strong filtration, moderate water movement, and a secure lid are important, as hawkfishes can jump when startled. This species is not ideal for peaceful community tanks unless tankmates are chosen carefully.

Diet and Feeding:

Lyretail Hawkfish are carnivores that do best on a varied meaty diet. Offer high-quality frozen foods such as mysis shrimp, enriched brine shrimp, chopped krill, finely cut seafood, and marine carnivore preparations. They may also accept small pellet foods formulated for predatory marine fish, especially if trained gradually. Feed small portions once or twice daily, only what they can consume in a few minutes. Because they are opportunistic hunters, they can become picky if overfed or given only one food type. A varied diet helps maintain color, energy, and immune health. Avoid relying on flake foods alone. Since they may eat ornamental shrimp and very small crustaceans, keep feeding consistent to reduce hunting behavior, though instinct cannot be eliminated completely.

Compatibility:

Lyretail Hawkfish are often described as semi-aggressive and highly territorial. They generally do well with larger, assertive, non-reef-shy fish such as tangs, wrasses, rabbitfish, angelfish, and larger clownfish, provided the tank is spacious. Avoid housing them with tiny fish, slow-moving species, or anything small enough to be swallowed, including gobies, very small blennies, and juvenile fish. They may also harass timid tankmates, especially in smaller aquariums. Invertebrate compatibility is limited: ornamental shrimp, crabs, and small snails may be viewed as prey. They are not considered fully reef-safe for shrimp-based invertebrate displays, though they usually leave corals alone. Introduce them after more peaceful fish if possible, and provide multiple perches and hiding places to reduce territorial disputes.

Health and Quarantine:

Lyretail Hawkfish are generally resilient, but stress from poor water quality, crowding, or poor diet can lead to disease. Quarantine all new specimens for at least 2–4 weeks to observe for marine ich, velvet, bacterial infections, or feeding issues. During quarantine, offer varied foods and watch for heavy breathing, flashing, or loss of appetite. Maintain pristine water and avoid sudden changes in temperature or salinity. Because hawkfishes are prone to injury from rough handling and can injure themselves while startled, use gentle acclimation and minimize netting. Regular water testing, dependable filtration, and a stable feeding routine are the best preventive measures.

Lyretail Hawkfish are perch-and-pounce predators that spend much of their time resting on rockwork and coral branches, then making short, deliberate dashes to inspect their surroundings, so they do best in a tank with plenty of ledges, caves, and hiding spots rather than open swimming space. They are generally semi-aggressive and highly territorial, especially toward conspecifics, which are best avoided unless in a very large system with broken sightlines. A minimum tank size of 30–40 gallons is recommended, though larger aquariums with strong rockwork and visual barriers help reduce aggression and give the fish secure perching territories. In mixed communities they are usually compatible with sturdy reef-safe species and noncompetitive tank mates, but small crustaceans and very timid fish may be harassed or eaten. Their diet is carnivorous, centered on meaty foods such as mysis shrimp, enriched brine shrimp, chopped seafood, and other small prey items offered several times per week. Because they are not grazers, they should be fed protein-rich portions that match their hunting behavior and prevent them from becoming overly opportunistic toward tank mates.

FAQ

Frequently Asked Questions

About the Lyretail Hawkfish

  • Will a Lyretail Hawkfish perch on my powerheads, overflow box, and rockwork, or does it need special “perch-friendly” aquascaping?
    Yes—Lyretail Hawkfish are classic perchers and will use rock ledges, coral skeletons, pumps, plumbing, and anything else with a stable edge. They do best in tanks with lots of branching live rock, caves, and overhangs so they can station themselves above the action and ambush food. Keep pump intakes well guarded, because a curious hawkfish can get too close while resting.
  • Can a Lyretail Hawkfish be kept with small ornamental shrimp, hermit crabs, and tiny snails, or will it eat them?
    It will very likely eat small crustaceans. Lyretail Hawkfish are opportunistic predators, and cleaner shrimp, sexy shrimp, peppermint shrimp, small hermits, and very small crabs are all at risk. Larger, tougher snails are usually ignored, but any mobile invertebrate that fits into its mouth is potential food. If you want a reef with decorative shrimp, this is not a safe choice.
  • Is a Lyretail Hawkfish reef-safe with corals, and what kinds of corals does it tend to bother?
    Generally yes with corals, because it does not eat coral tissue. The main reef concern is its habit of perching on coral branches and fleshy LPS/soft corals, which can cause irritation, retracted polyps, or broken tissue if the fish is heavy-handed. It is usually better with sturdier SPS and rockwork than with delicate branching or very fleshy corals. Mounting coral securely and giving the fish alternative perches helps a lot.
  • What tankmates are the biggest compatibility problem with a Lyretail Hawkfish, especially in smaller reefs?
    The biggest issue is with very peaceful, small fish and other perchers. Dwarf gobies, tiny blennies, juvenile cardinals, very small wrasses, and timid fish can be bullied, outcompeted at feeding time, or swallowed if they are small enough. Other hawkfishes and similarly shaped perchers can trigger territorial behavior. They do best with robust, medium-sized tankmates that won’t be intimidated by a bold, watchful predator.
  • What should I feed a Lyretail Hawkfish to keep it healthy, and how often should it be fed in captivity?
    Feed a varied meaty diet: frozen mysis, chopped krill, enriched brine shrimp, finely chopped seafood, and quality marine carnivore pellets. They usually eat aggressively and can be trained quickly to accept prepared foods. Feed once or twice daily in small portions, since they have high metabolism and thrive on regular feeding. A mixed diet is important to prevent nutritional gaps and to keep coloration and activity strong.
