Species Overview

Butterflyfish and Bannerfish are beautiful additions to the right marine tank. They have unique body shapes and usually display some variation in yellow, white, and black coloration.

Butterflies can be tricky to feed and maintain, and are not the best choice for beginner aquarists. If you have an established aquarium and you're able to provide the specialized diet required by many of these fish, there are some species that fare better than others in a captive environment.

Pennant Bannerfish and Raccoon Butterflyfish are considered to be some of the hardier and easier species to maintain from this group of fish, and may be good choices when you're ready. If you're considering Butterflyfish for your aquarium, be sure to research the dietary needs of specific species or talk to one of our marine biologists to find the right fit for your aquarium.

We always suggest that you do further research before adding a new pet to your tank. What we have provided for you are guidelines and suggestions. If you have any further questions or concerns, please contact our fish room at 717-299-5691 ext. 1213 or
