The Golden Hawkfish (Paracirrhites xanthus), also traded as the Golden Blue Line Hawkfish or yellow hawkfish, is a member of the family Cirrhitidae from the eastern central Pacific. Specimens reaching the aquarium market typically originate from Tahiti. Once a fish settles in and gains confidence, it colors up to a saturated banana yellow set off by a purple postocular mark behind the eye, a combination that makes it instantly recognizable among the hawkfishes. Its natural range is very limited, so it is rarely imported and commands high prices when it does appear.

Adults stay compact at roughly 4 inches, but plan on a 75-gallon aquarium or larger to give this fish the territory and swimming lanes it expects. Like other hawkfishes, it spends much of its time perched rather than cruising, so an aquascape with open rockwork, ledges, and elevated lookout points suits it far better than a flat, sparsely decorated layout. A secure lid is sensible, since perching fish are prone to launching themselves when startled or when jostling with tankmates. One documented specimen thrived in a very large, busy community reef system housing numerous other fish, which suggests a well-established display with plenty of structure is an appropriate home.

Care is best described as moderate. The fish itself is hardy and assertive once eating, but its scarcity, price, and the compatibility planning it demands mean it belongs with aquarists who have some experience managing mixed communities.
