Common name: Eastern triangular butterflyfish

General information

The Eastern Triangle Butterflyfish, also known as the Baroness Butterflyfish, is a striking species known for its unique coloration and triangular body shape. This species is scientifically referred to as Chaetodon baronessa. It is characterized by a white body with a broad black vertical band and a distinctive 'chevron' pattern. The vibrant yellow on the dorsal fin and tail adds to its appeal, making it a sought-after species for many aquarists.

Care

Chaetodon baronessa 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. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food is essential for maintaining their health and coloration.

Reproduction

In the wild, Eastern Triangle 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 open ocean before settling into the reef.

Symbiosis

While not known for a specific symbiotic relationship like clownfish with anemones, butterflyfish do play a role in the reef ecosystem by controlling algae and being part of the food web.

Habitat

The Eastern Triangle Butterflyfish is found in the Indo-Pacific region, from the Maldives to the Philippines, and north to southern Japan. They inhabit coral-rich areas of lagoon and seaward reefs, typically at depths of 2 to 20 meters.
