Common name: Crochet butterflyfish

General information

Guenther's Butterflyfish, scientifically known as Chaetodon guentheri, is a lesser-known species in the butterflyfish family. It is not as commonly found in the aquarium trade as some of its relatives, but it can be a captivating addition to a fish-only or a large reef aquarium due to its striking appearance and interesting behavior.

This species is characterized by its silver-white body with a series of vertical black stripes and a distinctive black spot on the tail. The snout is elongated, which is typical for butterflyfish, and they use it to pick food from crevices.

Care

Chaetodon guentheri requires a well-established aquarium with plenty of live rock for grazing and hiding. They are generally peaceful but can be territorial towards other butterflyfish. It's important to provide a varied diet that includes marine algae, small crustaceans, and other meaty foods to maintain their health and coloration.

Reproduction

Like many marine fish, Guenther's Butterflyfish are broadcast spawners, releasing their eggs and sperm into the water column where fertilization occurs. The larvae are planktonic and will settle after a period of growth in the open ocean.

Habitat

Guenther's Butterflyfish are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often in pairs or small groups, and can be found at depths ranging from shallow waters to over 30 meters deep.
