Cirrhitichthys falco

Datasheet

General Description

The Falco Hawkfish, scientifically known as Cirrhitichthys falco, belongs to the Cirrhitidae family, characterized by their still stance while waiting for food. These fish are native to the Indo-Pacific region, spanning from the Maldives to Samoa, northwards to the Ryukyu Islands, and southwards to the southern Great Barrier Reef and New Caledonia. With a maximum size of 7.0cm, they are relatively small in size.

Aquarium Suitability

Considered suitable for smaller aquariums if adequately equipped to meet their needs, the Falco Hawkfish is recommended to be kept in a tank larger than the minimum requirement of 100 liters. They are regarded as hardy fish and can coexist in pairs if introduced simultaneously. However, they exhibit aggressive behavior, especially towards smaller fish and crustaceans, making it crucial to provide ample hiding places and space to mitigate aggression.

Care and Hardiness

Falco Hawkfish are known for their unique hermaphroditic ability, where females can change to males as needed. They have fun and interesting personalities but are aggressive towards other species, requiring careful consideration when selecting tank mates. These fish do not have specific demands regarding water quality and can tolerate a range of parameters.

Reef Suitability

Categorized as reef-safe with caution, Falco Hawkfish can be a threat to smaller crustaceans in a reef environment. Careful monitoring is essential to avoid any potential harm to shrimp and crabs cohabitating in the tank.

Aquarium Setup

To create a suitable habitat for Falco Hawkfish, it is advised to include hiding spots for them, especially when first introduced. Maintaining a stable water temperature between 22.2-25.6°C, a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a carbonate hardness (KH) of 8-12 is recommended.

Behaviour

These fish may exhibit sudden aggressive behavior, potentially triggered by gender changes within the group. While larger Hawkfish might prey on small fish and crustaceans, species from certain genera are less likely to do so. Observing their interactions and being prepared to separate them if necessary is crucial in a mixed-species aquarium.

Feeding and Diet

Falco Hawkfish have a diverse diet that includes larger crustaceans like shrimp and crabs as well as smaller options like krill, mysis, and artemia. Regular feeding and a varied diet are essential to maintain their health and minimize aggressive tendencies.

Dimorphism

Apart from their hermaphroditic nature, Falco Hawkfish exhibit little dimorphism between males and females. Captive reproduction may occur in suitable conditions, but specific details on this aspect require further research.
