Sixline Wrasse - Pseudocheilinus hexataeni

The Sixline Wrasse (Pseudocheilinus hexataeni) is a vibrant and active fish commonly found in reef aquariums. Known for its striking coloration and lively nature, this small wrasse is a popular choice among marine aquarists who are looking for a beautiful and engaging species to add to their tanks.

Description:

• Common Name: Sixline Wrasse

• Scientific Name: Pseudocheilinus hexataeni

• Family: Labridae

• Size: Up to 3 inches (8 cm)

• Coloration: The Sixline Wrasse is easily recognized by its vivid, multi-colored body. It features six horizontal, bright blue lines running from its head to its tail, contrasting against its purple body. This striking pattern makes it stand out in any aquarium, especially when it is swimming among coral and rock structures.

• Lifespan: Typically lives for 4-6 years in a well-maintained tank.

Native Region:

The Sixline Wrasse is native to the Indo-Pacific region, including Hawaii, the Philippines, and Australia. It thrives in coral reefs and rocky environments, often hiding in crevices and feeding on smaller invertebrates.

Aquarium Setup:

• Tank Size: A minimum of 30 gallons (113 liters) is recommended for a single Sixline Wrasse. Larger tanks with plenty of live rock and hiding places are ideal to accommodate its active and curious nature.

• Substrate: A sandy or fine-gravel substrate is best, though this fish spends much of its time swimming rather than sifting through the substrate.

• Live Rock: Live rock provides essential hiding spots and grazing areas for the Sixline Wrasse. It will frequently dart in and out of rock crevices, using them for shelter and foraging opportunities.

Water Parameters:

• Temperature: 74-78°F (23-26°C)

• pH: 8.1-8.4

• Salinity: 1.022-1.025 specific gravity

• Hardness: 8-12 dKH

Care Level:

• Difficulty: Moderate. The Sixline Wrasse is a hardy fish but requires stable water conditions and an adequately sized tank to thrive. It is a relatively active fish, so ensuring enough space is essential.

• Diet: The Sixline Wrasse is carnivorous and feeds on small invertebrates, brine shrimp, and zooplankton in the wild. In the aquarium, it will readily accept frozen or live foods, including mysis shrimp, brine shrimp, and other meaty foods. Supplementing with high-quality pellets or flakes is also beneficial.

• Behavior: The Sixline Wrasse is known for being very active, swimming throughout the aquarium and displaying its characteristic darting behavior. It is inquisitive and enjoys exploring the tank. While generally peaceful, it can be territorial and may become aggressive toward smaller fish or other wrasses, particularly in smaller tanks.

Reef Compatibility:

• Reef-Safe: Yes, the Sixline Wrasse is generally reef-safe and does not pose a threat to corals or other invertebrates. However, it may consume smaller crustaceans or snails, so caution should be exercised when keeping it with delicate invertebrates.

Tank Mates:

• Suitable Companions: The Sixline Wrasse can coexist with a wide variety of reef-safe fish, including tangs, clownfish, and gobies. It’s important to provide enough space and hiding spots to reduce territorial behavior.

• Avoid: It is best to avoid keeping multiple wrasses of the same species in a confined space, as they can become aggressive toward one another. Additionally, it may be territorial toward smaller, more passive fish.

Additional Tips:

• Tank Setup: Live rock is crucial for providing hiding spots and territories, especially if you plan to keep more than one wrasse. Create plenty of nooks and crannies to reduce aggression and give the fish a sense of security.

• Behavior Observation: The Sixline Wrasse is highly active and often spends its time hunting and swimming across the aquarium. It is a pleasure to watch as it darts between rocks and coral, showcasing its dynamic movements.
