Common name: Guyot's Butterflyfish

General Information

The Guyot's Butterflyfish, scientifically known as Prognathodes guyotensis, is a rare and intriguing species within the aquarium trade. This elusive fish is named after its discovery location, a guyot or seamount at a depth of about 320 meter, and is known for its striking appearance and unique habitat preferences. Its rarity and distinct features make it a coveted species among advanced aquarists and marine biologists alike.

Guyot's Butterflyfish is not commonly found in the pet trade due to its deep-sea habitat and the challenges associated with its collection. However, its unique beauty and the allure of owning such a rare species make it a fascinating subject for those interested in marine biodiversity and conservation.

Care

Due to its rarity and specialized habitat requirements, the Guyot's Butterflyfish is best suited for experienced aquarists who can provide a stable and well-maintained environment. It thrives in aquariums that closely mimic its natural deep-sea habitat, with plenty of live rock and crevices for hiding. Maintaining pristine water quality and stable conditions is crucial for its health and longevity.

Diet and Feeding

In the wild, Guyot's Butterflyfish are believed to feed on small invertebrates and coral polyps. In captivity, they require a varied diet that includes high-quality marine-based foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Offering a mix of frozen and live foods can help ensure they receive the necessary nutrients.

Behavior and Compatibility

Guyot's Butterflyfish are generally peaceful but can be shy and reclusive, especially when first introduced to a new environment. They may exhibit territorial behavior towards conspecifics or similarly shaped fish, so it's advisable to house them with non-aggressive tank mates.

Health and Common Issues

As a deep-sea species, Guyot's Butterflyfish can be sensitive to changes in water quality and temperature. It's important to acclimate them slowly and monitor for signs of stress or illness. Regular water changes and a balanced diet can help prevent common health issues.

Habitat

Guyot's Butterflyfish are native to the deep waters of the Guyot Seamounts in the Pacific Ocean. They are typically found at depths ranging from 200 to over 300 meters, where they inhabit rocky outcrops and coral formations. Replicating these conditions in captivity can be challenging but is essential for their well-being.
