Pearlscale Butterfly (Chaetodon xanthurus) Care
The Pearlscale Butterfly, Chaetodon xanthurus come from both the Pacific and Indian Oceans. The body is an iridescent white color highlighted with a number of chevron-shaped grey lines, a black eye band, and a black crown. The rear part of the body, along with the dorsal and anal fins, is a bright golden-orange color.
This butterflyfish is an omnivore and requires a diet rich in both meaty foods and plant-based foods. They will eat flake food, algae, frozen plankton, mysis and brine shrimp, and live shrimp and worms. They should be fed several times a day. Should feeding be an issue when they arrive, get clams or black mussels from a local seafood store and place the food in a half-shell on the sand bed. Over time they can be fed frozen brine or mysis shrimp and black worms.
This Pearlscale Butterflyfish can reach lengths of up to 6″ and will do best in an aquarium of at least 75 gallons with plenty of live rock to graze on and hide in. They will thrive in a large fish-only aquarium with lots of open swimming space and live rock hiding places.
They are not reef compatible and will nip at both coral and invertebrates.
