Marginalis Butterfly
Marginalis Butterflyfish, Chelmon marginalus, is a rare, prized fish indigenous to Northern Australia. It is considered to be hardier than its close cousin, the Copperband Butterfly. Also known as the Three-Striped Longnose or the Margined Coralfish, its coloration resembles the Copperband Butterfly. Because of the middle stripe on the that the Marginalis does not display, its overall appearance seems to be a more vibrant white (sometimes nearly pearlescent!) than the Copperband. Its overall body conformation is also somewhat taller than its close cousin. Members of the genus Chelmon make gorgeous inhabitants of fish only aquariums. Soft Corals and most Invertebrates should do fine with the Butterflyfish, but it may likely decimate Stony Corals, as they are a part of its natural diet. Peaceful or non-aggressive tankmates are recommended to reduce stress on the Butterfly. When Butterflyfish are first introduced to the aquarium, they may refuse to eat. Should the fish continue this behavior for three or more days, live food should be offered (if not from the beginning). Food soaked in a garlic product will often entice the Butterfly to eat. Another useful method to encourage some Butterflyfish to eat is to place their food inside of a coral skeleton. Groupings of Butterflyfish can be introduced simultaneously in the same aquarium, making a stunning display. It is best to make sure that the fish have plenty of aquarium space each when adding a group. Live Rock and multiple places to hide also helps to reduce stress in a group introduction situation.
Approximate Arrival Size for Butterflies: Small: 1 to 2 in.; Medium: 2.5 to 3.5 in.; Large: 4 to 5 in.; XLarge: 5.5 to 6 in.
