Chevron Butterflyfish

The Chevron Butterflyfish is widely regarded as one of the most challenging butterflyfish to maintain in captivity, earning its expert-only classification through its strict dietary requirements. Named for the distinctive V-shaped or chevron-shaped markings that angle across its pale body, this species also features a bold black eye bar and a dark band along the rear edge of the body and tail. The overall appearance is subtle yet elegant, with fine lines converging in a herringbone pattern.

In the wild, Chaetodon trifascialis is an obligate corallivore, feeding almost exclusively on the mucus and polyps of Acropora corals. This extreme dietary specialization makes it exceptionally difficult to maintain in aquariums, as most specimens refuse all substitute foods. Only the most experienced and dedicated aquarists should attempt to keep this species, and even then, success rates remain low without a continuous supply of live coral or very gradual weaning onto prepared alternatives.

Despite its feeding challenges, the Chevron Butterflyfish is peaceful toward other fish and can coexist with a wide variety of tankmates. It is a graceful swimmer that patrols reef structures methodically. This species is absolutely not suitable for reef aquariums, both because it will consume corals and because it requires them as food. It is best suited to large, well-established fish-only systems where its dietary needs can be carefully managed.
