General Information

The Caribbean Longsnout Butterflyfish, scientifically known as Prognathodes aculeatus, is a striking species that captivates aquarists with its elongated snout and vibrant coloration. This species is a member of the Chaetodontidae family and is native to the Western Atlantic, particularly around the Caribbean Sea. Its unique appearance and intriguing behavior make it a fascinating addition to marine aquariums, although it is less commonly kept than some other butterflyfish species.

Despite its beauty, the Caribbean Longsnout Butterflyfish is not as prevalent in the aquarium trade due to its specific care requirements and dietary needs. It plays an important role in its natural habitat, contributing to the biodiversity of coral reef ecosystems.

Care

The Caribbean Longsnout Butterflyfish requires a well-established aquarium with plenty of live rock for grazing and hiding. It is best suited for experienced aquarists due to its specialized care needs. Maintaining pristine water quality and stable conditions is crucial for its health.

This species can be sensitive to changes in water parameters, so regular monitoring and maintenance are essential. A tank size of at least 200 liters (approximately 50 gallons) is recommended to provide ample space for swimming and exploration.

Diet and Feeding

In the wild, the Caribbean Longsnout Butterflyfish primarily feeds on coral polyps and small invertebrates. In captivity, it can be challenging to replicate its natural diet, making it important to offer a variety of foods. A diet consisting of high-quality frozen foods, such as mysis shrimp and brine shrimp, along with specialized marine pellets, can help meet its nutritional needs.

Feeding should be done multiple times a day in small portions to mimic its natural grazing behavior. Providing a varied diet is key to ensuring its health and vitality.

Behavior and Compatibility

The Caribbean Longsnout Butterflyfish is generally peaceful but can be territorial, especially in smaller tanks. It is best kept in a species-specific tank or with other non-aggressive fish that do not compete for the same food sources.

This species is not considered reef-safe, as it may nip at coral polyps and other invertebrates. Care should be taken when housing it with delicate corals or small invertebrates.

Reproduction

Breeding the Caribbean Longsnout Butterflyfish in captivity is extremely challenging and has not been widely documented. They are oviparous, releasing eggs into the water column, where they are fertilized externally. The larvae are planktonic and require specific conditions for survival, which are difficult to replicate in a home aquarium.

Health and Common Issues

The Caribbean Longsnout Butterflyfish is susceptible to common marine diseases, such as ich and marine velvet. Quarantining new additions and maintaining excellent water quality are essential preventive measures.

Selecting a healthy specimen involves looking for active behavior, clear eyes, and intact fins. Avoid individuals that appear lethargic or have visible signs of disease.

Habitat

This species is found in coral reefs and rocky areas at depths ranging from 3 to 50 meters (10 to 165 feet). Its distribution includes the Caribbean Sea, the Bahamas, and parts of the Western Atlantic. The Caribbean Longsnout Butterflyfish thrives in warm, clear waters with abundant coral growth, where it can find food and shelter.
