Family: Cirrhitidae ยท Hawkfish
Also known as: Blotched Hawkfish, Threadfin Hawkfish, Aprinus Hawkfish
The Spotted Hawkfish is a compact, hardy species that makes an excellent introduction to the hawkfish family for beginner marine aquarists. Its stout body is white to cream-colored, adorned with a pattern of reddish-brown to dark brown blotches and spots that provide effective camouflage against the rocky and coral surfaces where it perches. Like all hawkfish, it lacks a swim bladder and relies on its muscular pectoral fins to grip onto perching surfaces, from which it watches its surroundings with characteristically alert, intelligent eyes.
In the wild, the Spotted Hawkfish is found perched on coral heads and rocky outcrops in shallow to moderate-depth reef environments across the Western Pacific. It is an ambush predator that waits patiently on its perch before darting out to capture passing small crustaceans and zooplankton. Despite its predatory nature, it remains small at around 5 inches maximum, making it suitable for aquariums as small as 30 gallons.
The Spotted Hawkfish is remarkably hardy and disease-resistant, readily accepting all manner of frozen and prepared foods from its first day in the tank. It is semi-aggressive, meaning it will defend its chosen perching territory and may harass very small, timid fish, but it generally coexists well with most community reef inhabitants. Like other hawkfish, it will consume ornamental shrimp and very small crustaceans, so it should not be trusted with expensive cleaner shrimp. Its bold, curious personality and tendency to perch prominently in the open make it an engaging aquarium inhabitant that provides constant entertainment.
Spotted Hawkfish are carnivores that prey on small crustaceans and zooplankton in the wild. In captivity, they eagerly accept frozen mysis shrimp, enriched brine shrimp, chopped seafood, and marine pellets from day one. They are enthusiastic feeders that rarely refuse any meaty food offered. Feed two to three times daily.
The Spotted Hawkfish is generally compatible with most community reef fish of similar size or larger. It will prey on ornamental shrimp and very small crustaceans. May bully very small, timid species but is generally peaceful toward fish its own size or larger. Safe with corals of all types. Best kept singly as conspecifics will fight for perching territories.
Check CompatibilitySpotted Hawkfish are protogynous hermaphrodites, meaning dominant females can change sex to become males. Spawning occurs at dusk with pairs rising briefly into the water column. Eggs are pelagic and larvae are very small. Captive breeding has not been widely achieved in the hobby.
