Falco hawkfish

This species is widely distributed across the tropical Western Indo-Pacific. It is commonly found from the coastal waters of Indonesia and the Philippines to Samoa, ranging north to southern Japan and south to the Great Barrier Reef in Australia. It inhabits shallow coral reefs and reef flats rich in hard corals at depths between 4 and 46 meters.

Belonging to the family Cirrhitidae, it features a stocky, slightly elongated body with thickened lower pectoral fin rays that lack membranes, which are used as 'legs' to perch on rocks and corals. Adults reach a maximum length of about 7 centimeters. It also features small tufts of cirri at the tips of its dorsal fin spines.

It is a solitary, bottom-dwelling species with a strong territorial drive. It spends most of its time perched on rock ledges or branching corals (like Acropora) monitoring its surroundings. In the aquarium, it displays a curious and bold personality, protecting its favorite perching spot from other similarly sized fish.

The coloration consists of a whitish or pinkish base body color covered in a geometric pattern of reddish-brown spots and vertical bars. Two distinct diagonal red stripes run behind the eye down toward the gill cover. There is no visible external sexual dimorphism, and males and females look identical.

Can be housed in medium-sized marine aquariums starting from 100 liters. The tank layout must include plenty of live rock arranged to create flat shelves, elevated perches, and caves where the fish can sit and observe the aquarium. Ensure the rockwork is stable, as this fish jumps between rocks frequently.

It is a carnivorous predator. In captivity, it greedily accepts a wide range of foods, including frozen mysis, brine shrimp, krill, and chopped seafood. It also acclimates quickly to high-quality dry pellet foods. Feed at least once a day, ensuring it gets a share before faster swimmers consume all the food.

An exceptionally hardy and forgiving species. Maintain standard marine conditions: temperature between 24°C and 28°C, pH from 8.1 to 8.4, specific gravity from 1.020 to 1.025, and nitrates below 25 ppm. A standard filtration system with good water movement and oxygenation is sufficient.

It is reef safe with corals but not safe with small mobile invertebrates. It will actively prey on small ornamental shrimps (such as sexy shrimp or young cleaner shrimp) and tiny crabs. It coexists well with larger or active fish like clownfish, tangs, and wrasses. Avoid housing with small gobies.

Breeding in home aquariums is extremely rare. They are haremic protogynous hermaphrodites. Courting occurs at dusk, with the pair performing a quick vertical spawning run to release pelagic eggs into the water column. The larval stage is long and difficult to rear due to specific live feed requirements.

Highly resistant to common marine diseases and parasites. The main risk in captivity is the fish jumping out of the aquarium when startled or chasing prey. A tight-fitting lid or mesh screen is mandatory. It acclimates very quickly to the home aquarium environment.
