Banded Butterflyfish (Breeding, Characteristics, Habitat, Etc.)

Banded Butterflyfish

Banded Butterflyfish is a type of marine fish found in the tropical western Atlantic Ocean, ranging from Brazil to Bermuda.

It has several other names like Butterbun, Portuguese Butterfly, and School Mistress.

This fish’s name comes from its dark vertical bands that help break up its body shape as a defense against predators.

A black bar through the eye also helps with this. Banded butterflyfish lives in coral reefs and is found alone or in pairs.

Its diet consists of worms, coral polyps, crustaceans, and mollusk eggs. Sometimes, adults gather in groups of up to 20 for feeding on plankton.

Banded butterflyfish may even clean other reef fishes such as grunts, parrotfishes, and surgeon fishes that join their group.

This species is not safe for coral reefs.
