The Raccoon Butterflyfish, scientifically named Chaetodon lunula, is a popular and captivating species among marine aquarium enthusiasts due to its distinct coloration and markings. Here’s a comprehensive overview of the Raccoon Butterflyfish:
- Appearance:
- This fish boasts a warm yellow-orange body with dark patches around the eyes, which is reminiscent of a raccoon’s mask, hence the name. The rear part of its body may have a dark vertical stripe, and there is often a white stripe running down the middle of the body.
- Size:
- They can grow up to about 8 inches (around 20 cm) in length.
- Natural Habitat:
- The Raccoon Butterflyfish is native to the Indo-Pacific region, from East Africa to Hawaii, and can often be found in coral-rich lagoons and seaward reefs.
- Tank Requirements:
- Given their potential size, a tank of at least 125 gallons (around 473 liters) is recommended.
- The aquarium should have ample hiding places and open swimming spaces. Live rock formations can be beneficial for them to graze and find shelter.
- Diet:
- They are omnivores, feeding on a variety of foods including algae, coral polyps, and small invertebrates. In captivity, they can be given a diet comprising marine-based flake and pellet foods, mysis shrimp, brine shrimp, and other meaty preparations. It’s crucial to provide a varied diet for optimal health.
- Temperament:
- Generally peaceful with other species but might show territorial behavior towards other butterflyfish, especially in smaller tanks.
- Reef Compatibility:
- While they are quite stunning and many reef enthusiasts would love to have them, Raccoon Butterflyfish can be a risk in reef tanks. They are known to nip at soft and stony corals, and might consume some invertebrates.
- Care Level:
- Moderate. While they can be quite hardy once acclimated, they might be sensitive to drastic water quality changes.
- Health:
- As with other marine species, they can be prone to common fish ailments, such as marine ich. It’s essential to maintain stable water parameters and consider quarantining new arrivals.
- Lifespan:
- With proper care, they can live for several years, often around 5-7 years, in captivity.
The Raccoon Butterflyfish’s distinct appearance makes it a favorite for many marine aquarists. However, its potential incompatibility with corals and specific dietary needs means it’s best for those who are knowledgeable and prepared to meet its requirements.
