Care Guidelines: The Barhead Spinefoot thrives in well-established aquariums with ample swimming space and live rock for grazing. Due to its potential size, a tank of at least 120 gallons is recommended. While generally peaceful, it may exhibit territorial behavior towards conspecifics; therefore, it's best housed singly or as a compatible pair. Caution is advised when handling this species, as its dorsal and anal spines are venomous and can inflict painful stings. 

Diet: Primarily herbivorous, the Barhead Spinefoot requires a diet rich in vegetable matter. Offer a variety of marine algae, Spirulina-based foods, and fresh greens like blanched lettuce or spinach. Supplementing with meaty foods such as mysis shrimp can provide balanced nutrition. Feeding multiple times daily ensures optimal health. 

Reef Compatibility: When adequately fed, this species is generally reef-safe. However, underfeeding may lead to nipping at large-polyp stony corals and certain soft corals. Regular monitoring and a consistent feeding schedule can help mitigate this behavior. 

Compatibility: The Barhead Spinefoot coexists well with other non-aggressive species. Its venomous spines provide defense against potential predators, allowing it to be housed with more aggressive fish. Avoid keeping it with other rabbitfish to prevent territorial disputes. 

Special Considerations: Exercise caution during tank maintenance, as accidental contact with the fish's venomous spines can occur, especially when it adopts a camouflage pattern while resting. Using tools instead of hands when working near the fish can help prevent injuries. 

By adhering to these care guidelines, the Barhead Spinefoot can be a vibrant and beneficial addition to your marine aquarium, aiding in algae control and enhancing the tank's visual appeal.
