The Bluelashed Butterflyfish, also known as the Roche’s Butterflyfish or Chaetodon larvatus, is a lesser-known but striking member of the butterflyfish family. Here are some essential details about the Bluelashed Butterflyfish:
- Appearance:
- This species is predominantly yellow with a series of blue stripes radiating from behind the eye, resembling eyelashes, hence the name “Bluelashed.” The dorsal fin is elongated, and there’s often a black spot near the tail.
- Size:
- They usually reach a size of up to 6 inches (around 15 cm) in length.
- Natural Habitat:
- The Bluelashed Butterflyfish is native to the Indian Ocean, particularly around the waters of the Red Sea and Gulf of Aden.
- Tank Requirements:
- A minimum tank size of 75 gallons (around 284 liters) is generally recommended.
- They prefer an environment with plenty of live rock to graze on and hide within. The rock also offers territory and protection against potential aggressors.
- Diet:
- In the wild, their primary diet consists of coral polyps, invertebrates, and algae. In captivity, they should be provided with a varied diet of meaty foods, such as mysis shrimp, brine shrimp, and marine-based flake and pellet foods. Some specimens can be picky eaters initially, so a varied offering can help ensure they get proper nutrition.
- Temperament:
- Generally peaceful but may become territorial with conspecifics or similar-looking fish.
- Reef Compatibility:
- Due to their natural diet of coral polyps, they are often not recommended for reef tanks as they might nip at and damage corals, particularly the soft and stony types. However, they can be compatible with various invertebrates.
- Care Level:
- Moderate to high. Their specific dietary requirements and sensitivity to water quality mean they are best suited for more experienced aquarists.
- Health:
- As with many marine species, they can be susceptible to common fish diseases. It’s important to keep an eye on their health, quarantine new arrivals, and maintain a stable environment with high water quality.
The Bluelashed Butterflyfish is a unique and visually striking fish, but due to its specific needs and potential incompatibility with corals, potential keepers should be well-informed and prepared to meet its requirements.
