They are found in tropical and subtropical waters of the Indo-Pacific region, particularly in coral reefs and rocky areas. These fish are known for their vibrant colors and nocturnal habits, making them popular additions to home aquariums.
Characteristics
Astrapogon species are small to medium-sized fish, typically ranging from 5 to 15 centimeters in length. They exhibit a variety of striking colors, often displaying red, orange, yellow, and black patterns. A distinctive characteristic of Astrapogon is their elongated dorsal fin, which extends almost the entire length of their body. They also possess large eyes, which are well-suited for their nocturnal lifestyle.
Environment and Behavior

These fish are often observed in schools, providing safety in numbers against predators. They are also known to exhibit a unique reproductive behavior where the male cares for the eggs, which are typically deposited on a substrate like coral or rocks.
