Falco's Hawkfish

From Tropical Indo-Pacific, from the Maldives and East Africa east to Samoa, north to the Ryukyu Islands and south to the Great Barrier Reef and New Caledonia.12
At a glance the quick version
Looks how to spot one
Scaled, short and deep-bodied hawkfish
A small, compact hawkfish with a short, deep body. Each of its ten dorsal spines carries a little tassel of filaments, and the lower pectoral fin rays are thick and sturdy, ideal for propping itself up on rock. The pale body is decorated with reddish to red-brown bars and blotches.123
Personality what they are like
Alert and confident for its size. It watches the tank from a resting spot and can be bossy toward small newcomers, but it is generally manageable when given its own space.32
Daily activity how busy a day looks
Mostly sits on the bottom or on rock at the base of corals, then darts out to snap up food.12
Grooming and care the hands-on bits
Provide plenty of rock with ledges and hiding places, and avoid housing it with larger, pushier hawkfish. Typical reef water: about 22 to 26 °C (72 to 78 °F), pH 8.1 to 8.4, dKH 8 to 12, specific gravity 1.020 to 1.025.3
Home where they are happiest
A reef aquarium of at least about 30 US gallons (about 115 L) with ample rockwork. In nature it lives on reef flats and slopes, usually about 10 to 20 m deep, resting near the bases of corals.312
Food basics what goes in the bowl
Carnivorous. Wild fish eat small crustaceans, fish larvae and other bottom-living invertebrates; in captivity offer a mix of meaty marine foods and frozen preparations.213
Company who they like around
Found alone, in pairs or as a male with a small harem. In the aquarium a single fish is the usual choice.12
The story where it all began
John E. Randall described this hawkfish in 1963 from specimens collected in the Davao Gulf in the Philippines. Its species name is Latin for falcon, which fits the 'hawk' theme of the family's common name. It is occasionally offered in the aquarium trade.2
