The Arc Eye Hawkfish is a stunning addition to my reef tank. Its red eye ring is very noticeable and adds a unique touch. It spends most of its time perched on the rock, watching the surroundings. Very calm and doesn’t bother other fish. Only a bit cautious with tiny crustaceans, but overall a great choice.

I bought this fish for its unique appearance. It’s definitely a visual highlight. It’s not very active but stays in one place, which is nice. I’ve noticed it’s more curious than aggressive and doesn’t eat small invertebrates unless they’re very small.
