Care
Arc-eye Hawkfish are hardy and adaptable, making them suitable for both novice and experienced aquarists. They require an aquarium with plenty of live rock for perching and hiding. While generally peaceful, they can be territorial and may prey on smaller fish and invertebrates, so tankmates should be chosen with care. A varied diet of meaty foods will keep them healthy and vibrant.
Reproduction
In the wild, Paracirrhites arcatus exhibits a unique reproductive strategy where females release eggs into the water column, and males fertilize them externally. In the aquarium, breeding is less common, but environmental stability can encourage spawning behavior.
Habitat
Native to the Indo-Pacific region, Arc-eye Hawkfish are found in coral reefs and rocky outcroppings, typically at depths ranging from shallow waters to about 30 meters. They are adept at navigating the complex structures of the reef, which provides them with ample opportunities for hunting and shelter.
