Care

Caring for Raccoon Butterflyfish requires a well-established aquarium with plenty of live rock for grazing and hiding. They are generally peaceful but can be territorial with other butterflyfish. A varied diet of meaty foods, algae, and marine-based flakes or pellets is essential for their health. It's important to note that they may nip at some soft and stony corals, making them a better fit for fish-only or larger reef tanks with less sensitive coral species.

Reproduction

In the wild, Raccoon Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. While breeding them in captivity is challenging, understanding their natural reproductive behavior can be fascinating for hobbyists.

Habitat

Native to the Indo-Pacific region, Chaetodon lunula inhabits various reef environments, from shallow lagoons to deeper outer reefs. They are often found in pairs or small groups, gracefully navigating through the complex reef structures in search of food.
