Getting to Know the Red Spotted Hawk
The Red Spotted Hawk (Cirrhitops fasciatus), sometimes called the Hawaiian Hawkfish or Redbarred Hawkfish, is a small but bold reef inhabitant known for its vivid colouring and quirky behaviour. Sporting a white-to-pinkish body with vibrant red spots and bars, this hawkfish brings character and colour to any saltwater tank.
Native to the rocky reef slopes of Hawaii and other parts of the Indo-Pacific, these fish typically reach around 10 cm in length. They are well-loved for their unique tendency to perch on rocks and coral to survey their surroundings, watching the world go by with a confident, often comical attitude.
Choosing Your Red Spotted Hawk
When selecting a Red Spotted Hawk, look for one that’s active and alert, often found perching but quick to dart into action when food is present. Their body should be full and unblemished, with bright eyes and intact fins. Avoid fish with signs of skin damage, cloudy eyes, or sluggish behaviour.
These hawkfish tend to acclimate well and are known for being hardy, making them a good choice for both intermediate and advanced keepers.

Tank Setup and Environment
The Red Spotted Hawk is best suited to a tank of at least 100 litres, though larger setups are preferred if they’re going to be part of a community. They thrive in reef-style aquariums with plenty of rockwork, as they love to perch and observe from elevated spots.
A variety of ledges, caves, and overhangs will allow them to claim territory and feel secure. While they are generally considered reef-safe, caution is advised with very small ornamental shrimp or delicate fish, as hawkfish are opportunistic predators.
Use a secure lid—they can jump when startled.
Feeding and Nutrition
Red Spotted Hawks are carnivorous and have hearty appetites. In the wild, they feed on small crustaceans and invertebrates, and they adapt well to prepared marine foods in captivity.
Feed them a varied diet of:
Frozen mysis shrimp
Enriched brine shrimp
Chopped prawn, clam, or mussel
Marine carnivore pellets and flakes
Occasional live feeder shrimp (optional for enrichment)
Feed 1–2 times daily, ensuring they get enough protein to support their active metabolism and maintain their vibrant colours.
Behaviour and Compatibility
These fish are territorial but not overly aggressive, making them suitable for most peaceful community setups. That said, they may bully very timid or tiny fish if kept in close quarters.
Good tank mates include:
Clownfish
Tangs
Wrasses
Gobies (larger species)
Angelfish (dwarf or medium size)
Avoid keeping them with small ornamental shrimp, which may be seen as food, or other hawkfish, unless you have a very large system with clearly defined territories.
Water Conditions and Flow
Red Spotted Hawks are hardy but do best in stable, clean marine water with moderate flow. Good water movement helps simulate their natural reef environment and keeps waste from building up in the rockwork.
Temperature: 24–27°C
pH: 8.1–8.4
Salinity: 1.023–1.025
Flow Rate: Moderate
Nitrates: Below 15 ppm
Routine water changes and a quality filtration system are essential, especially if feeding heavy protein diets.
Health and Longevity
These hawkfish are generally resilient and not prone to many marine diseases if housed in stable conditions. They tolerate quarantine well and often eat within a day or two of arrival.
With proper care, the Red Spotted Hawk can live for 7–10 years, offering years of quirky behaviour and vibrant personality. They don’t require any special supplements, but a varied diet and enriched frozen foods will keep them thriving.
Final Thoughts
The Red Spotted Hawk is a fantastic addition to many saltwater aquariums, bringing not just colour but also personality. With their curious eyes and cheeky nature, they’re often found observing tank mates from their favourite perch—adding a unique dynamic to your underwater world.
For hobbyists looking for something a little different, yet easy to care for, this hawkfish is a wonderful choice that rarely disappoints.
