Common name: Butterflyfish

General information

The Hubbs' Butterflyfish, scientifically known as Prognathodes carlhubbsi, is a rare and beautiful species that is highly prized by advanced aquarists. This fish is distinguished by its deep yellow to orange body, with thin, vertical white stripes and a prominent black spot on the upper portion of its body near the dorsal fin. The species is named after Carl Leavitt Hubbs, an eminent American ichthyologist.

Care

Hubbs' Butterflyfish are considered challenging to keep due to their specialized dietary requirements and sensitivity to water quality. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These fish typically feed on a variety of sessile invertebrates in the wild, so a diet that includes live foods, such as mysis shrimp and enriched brine shrimp, is essential for their well-being in captivity.

Reproduction

Little is known about the breeding habits of Prognathodes carlhubbsi in the wild or in captivity. They are presumed to be broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Captive breeding of this species is rare and not well documented.

Habitat

Hubbs' Butterflyfish are found in the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands. They inhabit rocky reefs and steep slopes, often in cooler, nutrient-rich waters where upwellings occur. This species is typically found at depths ranging from 30 to over 150 meters, which is deeper than most butterflyfish species.
