Coral Hawkfish (Cirrhitichthys falco)

The Coral Hawkfish, also known as Falco's Hawkfish or the Dwarf Hawkfish, is one of the hobby's most characterful small fish and a perennial favourite among experienced reef keepers who know what they are getting into. Its white to pale pink body is covered in diagonal red-orange spots and bars that give it a rich, intricate patterning unlike almost anything else at its size, and the distinctive yellow-tipped cirri sitting atop each dorsal spine add a finishing detail that rewards close inspection. But the real appeal of this fish is its personality. The Coral Hawkfish lacks a swim bladder entirely, so rather than swimming freely it perches: wedged into a coral head, draped across a rock ledge, or planted at the highest vantage point in the tank, swivelling its head to track every movement in its environment, including the keeper's movements outside the glass. Bold, interactive, and endlessly watchable, it is one of the most engaging small fish available in the marine hobby. A clear-eyed understanding of its predatory instincts and moderate assertiveness is the key to keeping it well.

Why we love it

• Striking red-orange spotted patterning and yellow-tipped dorsal cirri make it one of the most visually detailed small fish in the hobby
• Legendary personality: few fish in the reef trade match the Coral Hawkfish for interactive, curious, keeper-aware behaviour
• Hardy, unfussy about food, and one of the easier carnivores to transition onto frozen and prepared diets
• Its perching, non-swimming lifestyle means it does not demand large aquarium footprints the way active open-water swimmers do
• One of the smaller hawkfish available in the trade, reaching only around 7 cm (2.8 inches), making it manageable in a wider range of system sizes
• Can be kept as a mated pair in larger systems, adding an interesting social dynamic

Suggested parameters

• Temperature: 22–26°C (72–78°F)
• Salinity: 1.020–1.025 SG
• pH: 8.1–8.4
• Alkalinity: 8–12 dKH
• Ammonia/Nitrite: 0
• Nitrate: Under 20 ppm; stable water quality supports long-term health

Care and temperament

• Difficulty: Easy to moderate
• Temperament: Moderately assertive; peaceful toward most fish of similar or larger size, but will predate small fish and ornamental shrimp, and can bully fish introduced after it is established
• Reef safe: With caution. Corals are completely safe and will be used freely as perching spots. Ornamental shrimp of any size are at significant risk. Cleaner shrimp and larger shrimp species carry moderate risk. Fish small enough to be swallowed will be targeted
• Minimum tank size: 30 gallons, with abundant live rock, ledges, and perching surfaces distributed throughout the aquascape

Diet

The Coral Hawkfish is a straightforward, enthusiastic carnivore that feeds instinctively and rarely requires coaxing.

• Frozen mysis shrimp and vitamin-enriched brine shrimp as the dietary foundation
• Finely chopped marine meats including clam, squid, and krill
• High-quality carnivore pellets and flake foods, which most individuals will accept readily once settled
• Live feeder shrimp can be useful for particularly reluctant feeders during the settling period, though the transition to frozen food should follow as quickly as possible
• Feed twice daily; this species has a fast metabolism for its size and benefits from regular, consistent offerings

Compatibility and tankmates

• Generally peaceful and compatible with fish of similar or larger size including tangs, angelfish, larger wrasses, clownfish, gobies, and blennies
• Will predate ornamental shrimp of virtually any size; do not house with cleaner shrimp, peppermint shrimp, or any other small crustaceans you wish to keep
• Will target small fish, particularly those slender or slow-moving species introduced after the hawkfish is established; avoid pairing with firefish, small dartfish, tiny gobies, or similarly passive and diminutive species
• Only one Coral Hawkfish per system is recommended unless keeping a deliberate mated pair; pairs should be introduced with a clear size difference to establish dominance without conflict, or added simultaneously to a large enough system
• Should not be housed with larger, more aggressive hawkfish species that will bully it
• Avoid dottybacks, damsels, and other assertive fish that may harass it persistently

Health and acclimation notes

The Coral Hawkfish is one of the hardier fish available in the marine hobby and typically begins feeding within the first day or two of introduction. Newly settled fish may be shy initially, spending the first few days tucked into rockwork before emerging to claim a preferred perch; provide plenty of ledges and crevices at different heights to give it options. Because it perches directly on corals, live rock, and any available surface rather than swimming, it does not require particularly large open swimming areas, but the aquascape should be rich enough to offer a genuine choice of vantage points. A tight-fitting lid is important; like many hawkfish, the Coral Hawkfish is capable of jumping, particularly when startled or newly introduced. Quarantine is always recommended before introduction to an established display, and the hawkfish should ideally be added before smaller, more passive fish to prevent established territorial behaviour from becoming a problem.
