What Do Butterflyfish Eat?

Butterflyfish are carnivorous marine creatures that primarily feed on small invertebrates found in coral reefs. Their diet consists mainly of coral polyps, worms, and crustaceans. They have long, slender snouts that allow them to reach into crevices and pick out their prey with precision.

These fish are not picky eaters and will consume a variety of food sources. They use their protractile mouths to snatch up their food, which they will then chew with their specially adapted teeth. With their keen eyesight, butterflyfish are expert hunters, always on the lookout for their next meal.

Common Prey of Butterflyfish

To get a better understanding of what butterflyfish eat, let’s take a closer look at some of their preferred food sources:

Coral Polyps

Coral polyps are the primary food source for many species of butterflyfish. These small colonial organisms form the building blocks of coral reefs. Butterflyfish will use their long snouts to probe into the coral crevices and extract the tasty polyps. They have no trouble snacking on a variety of coral species, from hard corals to soft corals.


Butterflyfish also have a taste for worms. Whether it’s tube worms, fireworms, or fan worms, these fish have no problem making a meal out of them. They will patiently hover near the worms’ hideouts and snatch them up as soon as they come within reach.


Crustaceans such as shrimps and crabs are another favorite food of butterflyfish. These agile swimmers will dart around the reef, searching for these delectable treats. Their specialized teeth allow them to crack through the tough exoskeletons of crustaceans and savor the juicy meat inside.

Unique Feeding Adaptations

Butterflyfish have some unique adaptations that help them to feed on their preferred food sources. Their long snouts enable them to reach into narrow crevices and extract their prey. They also have small, pointed teeth that are perfect for grasping and chewing their food.

Another interesting feature of butterflyfish is their ability to change color patterns. Some species have a false eye spot located at the rear of their dorsal fin. This spot can confuse predators by making them think the fish is swimming in the opposite direction. It’s a clever defense mechanism that allows butterflyfish to focus on their feeding without worrying too much about becoming someone else’s dinner.


The diet of butterflyfish consists mainly of small invertebrates such as coral polyps, worms, and crustaceans. These beautiful fish have long snouts and specialized teeth that help them capture and consume their preferred food sources. When keeping butterflyfish in aquariums, it’s important to provide a balanced and varied diet that resembles their natural feeding habits.

So next time you spot a butterflyfish gliding through the crystal-clear waters of a coral reef, remember that it’s on a mission to find its next tasty meal. These vibrant swimmers rely on the rich abundance of marine life in the reef ecosystem to satisfy their hunger and maintain their stunning appearance.
