The dwarf hawkfish (Cirrhitichthys falco) is a small, colorful fish that lives on coral reefs in warm, tropical parts of the Indo-Pacific Ocean. You can find it from the Maldives all the way to the Caroline Islands and Samoa. Sometimes, people even keep these interesting fish in home aquariums!

About the Dwarf Hawkfish Name
Scientists give every animal a special two-part name, like a first and last name, so everyone around the world knows exactly which animal they are talking about. The dwarf hawkfish's scientific name is Cirrhitichthys falco.
This fish was first officially described in 1963 by an American fish expert named John Ernest Randall. He found the first one in the Davao Gulf in the Philippines. The second part of its name, falco, comes from a Latin word meaning "falcon." Mr. Randall didn't say why he chose this name, but it might be a fun way to connect it to its common name, "hawkfish."
What Does a Dwarf Hawkfish Look Like?
The dwarf hawkfish is a small fish, growing up to about 7 centimeters (about 2.7 inches) long. It has some cool features that help it survive in its ocean home.
- Its top fin, called the dorsal fin, has ten strong spines. These spines have little tassels on their tips, which look like tiny fringes.
- The fin on its underside, the anal fin, has three spines and six soft rays.
- Its side fins, called pectoral fins, are thick and long. When the fish rests on the seabed, it spreads these fins out, almost like it's sitting down.
- The fish's body is a mix of pinkish-red and white. It often has vertical stripes or blotchy patterns that help it blend in with its surroundings.
Where Do Dwarf Hawkfish Live?
Dwarf hawkfish are found in tropical waters across the Indo-Pacific region. Their home stretches from the eastern coast of Africa and the Maldives, across to Samoa, the Ryukyu Islands in Japan, northern Australia, the famous Great Barrier Reef, and New Caledonia.
They are very common on the outer slopes and flat areas of coral reefs. You can find them living in waters from the surface down to about 45 meters (about 148 feet) deep.
How Do Dwarf Hawkfish Behave?
Dwarf hawkfish are often seen resting on large corals, using their strong pectoral fins to prop themselves up. They usually live alone, but sometimes you might spot them in pairs.
These fish are carnivores, meaning they eat other animals. They mostly feed on:
- Tiny fish larvae (baby fish)
- Small crustaceans, like tiny crabs or shrimp
- Other small invertebrates (animals without backbones) that live on the seabed
Life Cycle and Reproduction
Like many fish species, dwarf hawkfish have a fascinating ability: they can change their sex! This is quite unusual in the animal kingdom.
- Usually, a single male fish will be in charge of a group of several females. This group is sometimes called a "harem."
- If this group gets too big, one of the females might change into a male. This new male can then take over part of the group.
- What's even more amazing is that if a new male is challenged by a stronger male, it can actually change back into a female! This allows it to still lay fertile eggs and have babies. This ability to switch back and forth is very rare and helps the species survive and reproduce successfully.
