Common name: Margined coralfish
General information
The Eastern Talma, scientifically known as Chelmon marginalis, is a distinctive species of butterflyfish. It is closely related to the more commonly known Copperband Butterflyfish (Chelmon rostratus). With its elongated snout and striking coloration, it is a sought-after species for advanced marine aquarists. The Eastern Talma is characterized by its white body with thin black vertical stripes and a yellow margin on its dorsal, anal, and caudal fins.

Care
Chelmon marginalis requires a well-established aquarium with plenty of live rock for grazing and hiding. This species is known for being somewhat delicate and requires pristine water conditions. A varied diet is crucial, including small crustaceans, worms, and prepared foods. Due to its specialized feeding habits, it may not be suitable for beginners.
Reproduction
In the wild, butterflyfish generally form monogamous pairs during the breeding season. However, breeding Chelmon marginalis in captivity is quite challenging and rarely achieved by hobbyists. They are broadcast spawners, releasing eggs and sperm into the water column.
Habitat
The Eastern Talma is found in the Western Pacific, from the Great Barrier Reef to the Solomon Islands. It inhabits coral-rich areas of lagoons and outer reefs, often seen at depths where light is sufficient for coral growth.
