The Copperband Butterfly, Chelmon rostratus, has a silver sheen body with several copper bands and a long protruding snout tipped with a small mouth, and a small black dot on the end of its dorsal fin. They are peaceful and can be kept with other peaceful fish, but may become aggressive towards other Butterflies with a similar pattern or coloration in smaller tanks.

They are also not reef safe since they will nip at and eat soft corals and stony polyps as well as ornamental shrimp, tube worms and anemones. Diet should include a variety of mysis and vitamin enriched brine shrimp, spirulina, nori, seaweed, marine algae, and algae based foods, 2-3 times daily.
