Description
These fish are easily identified by the yellow banding and long snout, juveniles being similar to adults. They grow up to 20 cm in length[1]
Habit and habitat
Found at depths of 1-25 metres either singly or in pairs, forming monogamous pairs during breeding. They are usually found on coral reefs or rocky shorelines, and also in estuaries and silty inner reefs. This species is territorial and oviparous.[1]
Points of note
They may be distinguished from the similar Chelmon marginalis by their color pattern and number of dorsal fin rays.[1]
In the aquarium
Copperband butterflyfish can grow to 8 inches (20 cm) but in a home aquarium are usually found at half that size.[citation needed] They do well at a normal reef temperature range of 75 to 84 °F (24 to 29 °C), with a tank size of at least 75 gallons[vague] with lots of live rock to graze on. This species can be considered reef safe. It will eat many invertebrates, including parasitic forms such as Calliactis parasitica and common glass anemone (aiptasia) (Parasitic anemone).The Aipitasia is the last choice of food though; all tube and substrate worms,clams,mollusks are its prey. This is not a recommended fish for inexperienced aquarists, as it requires excellent tank conditions to thrive or even survive.
