Arc Eye Hawk – Paracirrhites arcatus

About this fish

Arc Eye Hawk – Paracirrhites arcatus is a hawkfish species for saltwater aquariums, identified by its scientific name Paracirrhites arcatus. It’s a rock-dwelling, bottom-to-midwater predator that adds active, reef-like behavior to a well-established tank. Practically, it’s a good choice for hobbyists who want a fish that perches on live rock and feeds on small meaty foods during routine feeding.

Features:

• Perches on rock and scans from elevated spots, making it an engaging addition to reef aquascapes
• Best suited to an established marine aquarium with plenty of live rock and hiding places
• Generally compatible with many community reef setups when tankmates are appropriately sized and non-aggressive
• Consumes a variety of small, meaty foods once settled into aquarium feeding routines
• Helps bring movement to the midwater/rockwork zone through active, alert hunting behavior

Specifications:

• Care level: Moderate (needs stable, established saltwater conditions and consistent feeding)
• Temperament: Active, observant, and predatory toward small animals; typically best with tankmates too large to be targeted
• Tank placement: Bottom to midwater; often perches on live rock
• Adult size: Typically several inches long
• Diet: Meaty, carnivorous foods such as small marine meaty offerings
• Temperature: Tropical reef range (commonly mid-to-high 70s °F)
• Salinity: Reef-appropriate marine salinity (commonly ~1.020–1.026 specific gravity)
• pH: Reef-stable pH (commonly ~8.1–8.4)
