(Lacepède, 1802)

The Raccoon Butterfly is a very attractive species that makes for a nice addition to the home aquarium. Though not as attractive as its namesake in the Red Sea (C. fasciatus), the Indo-Pacific Raccoon is just as hardy, and a very good choice for eating pest Aiptasia anemones in reef tanks, though it will consume coral polyps in some cases. Also used to eat Aiptasia, and though more "reef safe" than the Auriga, still not to be entirely trusted.

Husbandry know-how of owners

Chaetodon lunula, also known as the Raccoon butterflyfish, Red striped butterflyfish, Moon- or Half moon butterflyfish is one of the hardier of the butterfly species. In the wild it is primarily nocturnal, meaning that it is most active at night. Provide plenty of hiding places to help make your Raccoon Butterfly feel secure.

Chaetodon lunula can reach up to 8 inches (20 cm) so you will need a fairly large aquarium to keep one. Please avoid keeping them with other butterflys because the Raccoon Butterfly can become very territorial but should get along well with most other species in the aquarium.

The Raccoon Butterfly fish is seem to be prone to cryptocaryon, for this reason you should definitely quarantine this fish before introducing it to your aquarium (DT).


Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.

Hatte schon 2 Lunulas in den vergangenen 2 Jahren, aber ohne Erfolg. Einer verstarb nach 3
Monaten und der andere bereits nach 3 Wochen.
Dabei gab es keinerlei Anzeichen von Krankheiten.
Die bekannten Pünktchen oder gar Lymphocystis
sind für ihn ein Fremdwort. Sie fraßen gierig das
gängige Frostfutter, wobei Artemia der Favorit war.
Trockenfutter wie Granulat oder Flockenfutter ignorierten sie leider. Ich will nicht glauben das
dieser Fisch nicht pflegbar ist, stattdessen vermute
ich eher ein schlechte Zwischenhälterung mit viel
Antibiotika, oder Giftfang. Ich für meinen Teil werde es vorerst nicht mehr versuchen, denke das
ist nachvollziehbar.
Übrigens: Der Lunula ist ein sehr ruhiger und friedlicher, aber keinesfalls feiger Falterfisch und er ist wunderschön. Ganz aus meinem Gedächtnis
wird er sicher nie verschwinden!

An easy fish to keep. Tolerant of water quality variations. Will usually eat almost any commercially available food. Peaceful fish. I've not seen one react badly towards any other B or fish in fish-only aquaria. As always with most butterflyfishes, it is best to put into quarantine in order to get it eating different foods, and to get it used to humans (as well as to be sure it is disease-free).
