True Falcula Butterflyfish (Chaetodon falcula)


The Falcula Butterflyfish, otherwise known as the Sickle Butterflyfish, have elongated snouts and are for the most part white in body. Over their eyes, they are marked with a vertical, black bar and they have two black patches over their dorsal region. These fish are yellow in color around their dorsal, anal, and caudal fin areas and are marked with a black dot on their tails.


It is best to house these fish in a 125 gallon tank or larger with live rock for grazing and plenty of room for swimming. They are not the best reef dwellers. The Falcula Butterflyfish tends to eat and nip at soft and stony corals (sessile invertebrates) and anemones. These butterflyfish are rather peaceful and can be kept with other types of fish or other peaceful butterflyfish.



The diet of the Falcula Butterflyfish should include: frozen preparations, crustacean flesh, mysis shrimp, anemone (as a treat), and other meaty foods.
