Aquarium Suitability
Considered suitable for aquariums with care, the Giant Hawkfish thrives best when provided with good hiding places, such as between live rocks, due to their nocturnal nature. While they do not have many demands regarding water quality, it is recommended to house them in a tank of at least 600 liters. Their reef compatibility is labeled as safe with caution.
Demands, Care, and Hardiness
Giant Hawkfish are hardy fish that do not require specific water conditions. They are known to be aggressive towards smaller fish, crustaceans like shrimp and crabs, and even towards other fish species. Keeping multiple Hawkfish together can lead to sudden fights, possibly due to gender changes within the group.
Reef Suitability
Reef tanks can house the Giant Hawkfish, but caution is advised due to their aggressive nature towards smaller tank inhabitants like crustaceans. Their preference for dim lighting and ample hiding spots make them suitable for reef environments, provided proper care is taken with tank mates.
Aquarium Setup
Creating an aquarium setup for Giant Hawkfish involves offering ample hiding places, like live rocks, and ensuring a tank size of at least 600 liters. Maintaining a dimmed or turned-off light cycle can cater to their nocturnal activity, while keeping them singly or with compatible tank mates is recommended to avoid conflicts.
Behaviour
