Common name: Brazilian Butterflyfish

Scientific name: Prognathodes brasiliensis Burgess, 2001

General information

The Brazilian Butterflyfish, scientifically known as Prognathodes brasiliensis, is a striking species known for its vibrant coloration and unique patterning. This species is a member of the family Chaetodontidae, which includes all butterflyfish. It is characterized by its deep yellow to orange body with vertical white bands and a prominent black spot on the dorsal fin. The Brazilian Butterflyfish is not as commonly found in the aquarium trade as some other butterflyfish due to its specific habitat requirements and limited range.

Care

Prognathodes brasiliensis requires a well-established aquarium with plenty of live rock for grazing and hiding. This species is known for being somewhat delicate, so stable water conditions and a varied diet are crucial for its well-being. They primarily feed on benthic invertebrates in the wild, so a diet that includes marine sponges, small crustaceans, and other meaty foods is recommended. Due to their specialized feeding habits, they may not be suitable for beginners.

Reproduction

In the wild, Brazilian Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting in the currents until they develop into juveniles and settle onto the reef. Reproduction in the home aquarium is rare and challenging.

Habitat

Prognathodes brasiliensis is endemic to the Western Atlantic, particularly around Brazil, where it inhabits rocky reefs and slopes. It is typically found at depths ranging from 30 to 120 meters, which is deeper than most recreational scuba diving limits. This depth preference contributes to its rarity in the aquarium trade, as collecting specimens can be more difficult and costly.
