Lined Butterflyfish

General information

The Lined Butterflyfish (Chaetodon lineolatus) is a popular saltwater aquarium species due to its striking appearance. It can grow up to 8 inches (20 cm) in length and has a vertical stripe pattern of white and black lines that run the length of its body. This species is generally peaceful and can be kept in small groups of 3-5 individuals in a tank of at least 75 gallons.

In the wild, Lined Butterflyfish feed on a diet of coral polyps, small crustaceans, and algae. In captivity, they can be fed a variety of prepared aquarium foods including flakes, pellets, frozen or live brine shrimp, and mysis shrimp. It is important to provide a varied diet to ensure the fish receive all necessary nutrients.

It is difficult to distinguish between male and female Lined Butterflyfish without observing them during spawning.

Lined Butterflyfish are not commonly bred in captivity.

Lined Butterflyfish are generally hardy and disease-resistant when kept in a well-maintained aquarium. However, they are susceptible to common saltwater fish diseases such as marine ich and marine velvet. Quarantining new fish before introducing them to an established aquarium can help prevent the spread of disease.

The Lined Butterflyfish is found in the western Pacific Ocean, including the Great Barrier Reef, and throughout the Indian Ocean.

Lined Butterflyfish are generally peaceful but may become aggressive towards other butterflyfish or similarly shaped fish. They should not be kept with aggressive fish species.

It is important to acclimate Lined Butterflyfish slowly to their new aquarium to reduce stress and prevent disease. The drip acclimation method is recommended, slowly adding small amounts of water from the aquarium to the fish's transport bag over the course of an hour or more.
