Chaetodon argentatus, also known as the Black pearl butterflyfish and Silver butterflyfish; inhabit coral reefs and occurs in pairs or small groups, usually in areas of dense coral growth. The body of the Black pearl butterflyfish is laterally compressed and silvery white in color, with some scales edged in black. A black bar is present through the eye but is often indistinct. A second bar from the dorsal to the pectoral base is clearer. A wide mid-body bar ends halfway down the side and the fourth bar, much clearer defined, extends across the caudal base from the soft dorsal to soft anal fins. The belly is often bright yellow in juveniles and there are two dark bars on the tail.
Chaetodon argentatus is quite well to keep in large enough aquariums and is one of the hardier species of Butterflyfishes and sometimes inclined to be aggressive towards his smaller own kind.
The Black pearl butterflyfish is mostly collected in the Central Indo-Pacific to the Indo-West Pacific. It growth to a maximum of 20 cm (7.87 in); Chaetodon adiergastos is very seldome imported for the hobby although they can be easily maintained in a tank.
Most foods are accepted but a particular favourite is frozen adult brine shrimp and Mysisd shimp.
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.
