Chaetodon falcula also known as Blackwedged butterflyfish or True Falcula Butterfly grows up to 20cm (8 inches) and is mostly white becoming yellow dorsally. It has a series of narrow black stripes on its sides, two patches of black on the dorsal side, and a black eye band.
The Blackwedged butterflyfish prefers a tank with plenty of places to hide & swim. It will eat anemones and mushroom anemones, coral polyps, fanworms and feather dusters causing problems in a reef aquarium.
Chaetodon falcula is a carnivore and likes to eat variety of meaty foods. It is a hardy addition to fish only and very large reef systems.
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.
Fairly easy to keep. Will adapt to a variety of aquaria. Will eat a wide variety of commercially available foods. 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).
