The Chevron Butterfly (Chaetodon trifascialis) is a unique Butterflyfish found widely distributed among the Indo-Pacific Ocean. They have a pale body with black chevrons and golden-yellow dorsal and anal fins, along with a black stripe acting as a false eye. They are very hardy and peaceful and can be kept with other peaceful fish, but may become aggressive towards other Butterflies with a similar pattern or coloration in smaller tanks.
They are also not reef safe since they will nip at and eat soft corals and stony polyps as well as ornamental shrimp, tube worms and anemones. Diet should include a variety of mysis and vitamin enriched brine shrimp, spirulina, nori, seaweed, marine algae, and algae based foods, 2-3 times daily.

The Chevron Butterfly (Chaetodon trifascialis), also known as the Three-banded Butterflyfish, is a popular choice for saltwater marine aquarium enthusiasts due to its striking appearance and relatively easy care requirements. Here's a detailed overview of this species to help aquarists understand how to care for them properly in captivity.

Diet of the Chevron Butterfly in Captivity

Chevron Butterflyfish are omnivores and feed primarily on a diet of algae, coral polyps, and small invertebrates in the wild. In captivity, they can be fed a varied diet of high-quality flake or pellet food supplemented with frozen or live brine shrimp, mysis shrimp, and algae sheets.
