Fish World | Beauty  Raccoon butterflyfish, Chaetodon lunula | The raccoon butterflyfish, Chaetodon lunula, also known as the crescent-masked butterflyfish or lunule butterflyfish is a species of butterflyfish (family Chaetodontidae). It is found in the Indo-Pacific region and in the southeast Atlantic. The length is 20 cm (nearly 8 in).

Chaetodon lunula is known by different names in English, as Racoon Butterflyfish, Raccoon Butterfly, Racoon Coral Fish, Halfmoon Butteflyfish, Mon Butteflyfish, Moon Butterfly fish, and Redstriped Butterflyfish.

It belongs to the large subgenus Rabdophorus which may lead to recognition as a separate species. In this group, its closest relative is probably very similar to the Red Sea raccoon butterflyfish butterflyfish or diagonally, C. fasciatus. Other close relatives like the black butterflyfish, C. flavirostris), Philippine butterflyfish, C. adiergastos, and perhaps the unusual red-tailed butterflyfish, C. collars are. Although the color of this group varies widely, they are all fairly large with an oval outline Coral Butterflies, and most have a pattern of ascending oblique stripes on the sides. Except in the red-tailed butterflyfish, there is at least a rudimentary form of "raccoon" mask with a white space between the dark crown and eye areas.
The Racoon Butterflyfish lives in the Indo-Pacific and South-East Atlantic. The geographic range extends from East Africa to Hawaii and the Marquesas and Ducie Islands. The northern boundary lies south of Japan, whereas the southern boundary is located in the waters of Lord Howe Island and Rapa. In the southeast Atlantic Ocean, the species is found from East London in South Africa. (The Racoon Butterflyfish Chaetodon lunula is not present in the Red Sea into the Red Sea, you instead find the closely related Chaetodon fasciatus known under the same common name .. - Racoon Butterfly)
The adult Racoon Butterflyfish inhabits shallow reef flats of the lagoons and seaward reefs, while the young tend to prefer to stay between the inner reef flats on rocks and in tide pools. The depth range for this species is 00 to 30 meters / 000 to 100 feet.

The Racoon Butterflyfish is primarily a nocturnal species and is usually found in pairs or small groups.

The raccoon butterflyfish is generally not aggressive toward other fish, except the lionfish  and triggerfish. In captivity, the typical lifespan of a raccoon butterflyfish is five to seven years. It is perceived as a beneficial predator of Aiptasia and Majano anemones. They will eliminate this nuisance pest within a period of two to six weeks, depending on the anemone population and the size of the tank, but they will eagerly feed on soft corals and can cause more harm than good to the device to cause. In a closed environment, this species is susceptible to succumb to "marine ich", Cryptocaryon irritans infection by the ciliate.
The largest scientifically measured Racoon Butterflyfish was 20 cm / 7.9 inches. The fish called Racoon Butterflyfish because the black markings around his eyes. Black marks can also be found in various other parts of the body over a yellow base color.

It is not recommended for an adult racoon butterflyfish to keep in an aquarium smaller than 75 gallons / 285 liters. A small copy can do well in a 15 gallon / 60 gallon tank, but it will eventually need a bigger house. This species is not properly deal with displacement. The aquarium should contain a lot of suitable hiding places (eg integers) and open areas for swimming.

The Racoon Butterflyfish is generally peaceful and can be stored in a friendly community aquarium. However, it will be against other territorial butterflyfish and you will have a very large and cleverly decorated aquarium necessary if you wish to keep them together. You can also reduce risk of aggressive behavior by just keeping butterflies of different sizes and introduce the smallest first (wait a few weeks between each introduction). In the wild these fish can be seen in groups, but it can be difficult to get a group to co-exist in the aquarium, unless they are caught together.

The Raccoon Butterflyfish is generally not considered reef safe, because they like to get some corals and invertebrates eat.

Keep the pH at 8.1-8.4 and specific gravity within the range 1020-1025 (ideally in the upper parts of this series). The recommended water temperature when keeping Raccoon Butterflyfish is 72 to 78 ° F / 22 to 25.5 ° C. Like the other butterflyfish, the Racoon Butterflyfish is sensitive to organic waste and it is therefore recommended only for established aquariums.
