Arc-eye Hawkfish

The Arc-eye Hawkfish is a striking marine fish known for the blue-and-orange arc-shaped marking behind its eyes, paired with a white stripe along the rear half of its body. It likes to perch on branching corals, waiting patiently to ambush passing prey. Hardy and adaptable, it's often considered a good choice for those just starting out in marine fishkeeping. That said, it has a strong territorial streak and can be aggressive toward similarly sized fish, and its instinct to hunt small shrimp, crabs, and fish means tankmates need to be chosen carefully in a reef setup. Since it grows to around 20 cm at full size, it's worth planning tank space with its adult size in mind.

About Arc-eye Hawkfish

The Arc-eye Hawkfish is a hardy, beginner-friendly marine fish with striking blue-orange eye markings. It is territorial and preys on small shrimp and fish, so reef tankmates should be chosen with care.

7 things to know before welcoming a Arc-eye Hawkfish

1Strongly Territorial
The Arc-eye Hawkfish tends to stake out its own patch of the tank and can chase off fish added later, especially near its favorite perch. When introducing tankmates, make sure there is enough space and enough hiding spots to go around.
2Risk to Shrimp and Small Fish
It reacts quickly to movement and will prey on small shrimp, crabs, and small fish. If keeping invertebrates in a reef tank, avoid adding anything small enough to become a meal.
3Needs a Perching Spot
In the wild, it perches on branching coral to ambush passing prey. Providing live rock or branching coral in the tank gives it a natural spot to settle and feel secure.
4Tight-Fitting Lid Needed
Hawkfish are active swimmers and can leap out of the water when startled. Use a well-fitted tank lid to prevent accidental jumping incidents.
5Hardy and Beginner-Friendly
This species tolerates changing conditions reasonably well, making it approachable even for those new to marine fishkeeping. Even so, avoid sudden swings in water quality and keep up with regular water changes.
6Grows to About 20 cm
Adults reach roughly 20 cm in length. Plan your tank size around this eventual size so the fish doesn't outgrow its home.
7Compatibility With Its Own Kind
Because of its territorial nature, keeping multiple Arc-eye Hawkfish together often leads to conflict. If you want to house more than one, provide a spacious tank with plenty of hiding places.
