Arc-eye hawkfish is found in shallow waters in the tropical IndoPacific on reefs, resting on coral heads much of the time. Arc-eye hawkfish grows to a maximum size of 20 cm in length, and occurs in a variety of colors. The body may be greenish-brown, dark brown or reddish-orange, while the tail usually is bluish. A broad, longitudinal white band runs along the distal half of the body. A characteristic ring-shaped or U-shaped tricolor marking (red, blue and yellow) occurs around and behind the eyes.
The genus name Paracirrhites derives from the Greek word para, meaning "the side of" plus the Latin word cirrus, meaning "curl". The species name arcatus, meaning "arched", refers to the U-shaped marking around the eyes.
Paracirrhites arcatus 's Behavior & Ecology
The arc-eye hawkfish is a benthic species associated with coral reefs. It usually can be found in lagoon and seaward reefs, at a depth of 1–30 m (3 ft 3 in–98 ft 5 in), with a maximum of 91 m (299 ft).
Paracirrhites arcatus 's Feeding
These voracious predators are very territorial. They spend most of their time perched on corals, especially Acropora, Stylophora, and Pocillopora genera, waiting for prey to approach too close. They mostly feed on small fishes, shrimps, and crabs but also eat isopods, fish eggs and larvae.
Paracirrhites arcatus 's Reproduction
Distinct pairing. Spawning ascents into the water column occurred over a distance of 0.4 to 1.0 m.
Paracirrhites arcatus 's Relationship with Humans
These fish can be seen in the aquarium trade.
Paracirrhites arcatus habitat
Paracirrhites arcatus is a solitary species that inhabits coastal lagoons and seaward reefs at a depth between 1 m and 35 m (Allen and Erdmann 2012), but has also been reported at a depth to 91 m (Myers 1999). It is usually found perching on small branching corals, often Pocillopora,Stylophora, and Acropora coral heads (Lieske and Myers 1994). This species has a maximum total length of 9 cm (Allen and Erdmann 2012). It feeds mainly on shrimps, small fishes, crabs, and other crustaceans (Randall et al. 1990).
Paracirrhites arcatus threats
Although Paracirrhites arcatusis collected for the aquarium trade, there are no known major threats at this time.
