The Six-line Wrasse (Pseudocheilinus hexataenia) is a colorful and active fish commonly found in the marine aquarium trade. It’s a favorite among many aquarists due to its vibrant appearance and lively behavior. Here’s a detailed overview of the Six-line Wrasse:
- Appearance: This wrasse is named for the six distinct horizontal blue lines that run the length of its body, contrasting against a bright orange-red background. It also features an eyespot near the base of its dorsal fin and has a pointed snout, which it uses to pick off pests and small invertebrates.
- Size: A relatively small fish, the Six-line Wrasse typically reaches a maximum length of around 3 inches (7-8 cm).
- Habitat: Native to the tropical waters of the Indo-Pacific, this species inhabits lagoons and coral-rich areas of reefs.
- Behavior: Six-line Wrasses are known for their active swimming patterns and curious nature. They often dart around the aquarium, exploring and looking for food. They have a habit of burrowing into the sand or hiding among rocks when they feel threatened or during the night.
- Diet: These wrasses are carnivorous and feed on a variety of small invertebrates, including copepods, amphipods, and other small crustaceans. In the aquarium, they can be fed a mix of high-quality marine flake food, frozen mysis shrimp, brine shrimp, and other meaty preparations.
- Aquarium Care:
- Tank Size: While they are small, a tank of at least 30 gallons is recommended due to their active nature.
- Water Quality: As with most marine species, maintaining stable water parameters is essential for the health of the Six-line Wrasse. Regular water changes and monitoring are crucial.
- Tank Mates: Generally, they are peaceful towards most tank mates, but they can display territorial aggression towards other wrasses or similar species, especially in smaller tanks.
- Environment: Provide them with plenty of live rock for hiding and foraging. They also appreciate a sand bed, as they may burrow when feeling threatened.
- Reef Compatibility: Six-line Wrasses are generally considered reef-safe, but they might prey on small ornamental shrimp or other tiny invertebrates.
- Lifespan: With proper care, a Six-line Wrasse can live up to 5 years or more in captivity.
- Interesting Fact: The Six-line Wrasse is often sought after by reef aquarium hobbyists as a natural means of pest control. They are known to eat pyramidellid snails and flatworms, which can be problematic in reef setups.
In conclusion, the Six-line Wrasse is a colorful and engaging addition to many marine aquariums. However, like all fish, they have specific needs that must be met to ensure their health and happiness in captivity. If considering one for your tank, thorough research and preparation are essential.
