General Description
The Filamentous Wrasse, also known as the Filamented Flasher, Filament-fin Wrasse, or Filamentous Flasher Wrasse, belongs to the Labridae family. These colorful fish, specifically the Paracheilinus genus, are vibrant and spend most of their time swimming in the water column. The males are usually more striking with longer filaments on their dorsal fins. Identifying between species within this genus can be challenging due to their similar appearances and behavior. These fish are peaceful but shy, so they should not be housed with aggressive tank mates. In captivity, maintaining their vivid colors can be tricky, requiring a varied, high-quality diet.
Aquarium Suitability
The Filamentous Wrasse is considered suitable for aquariums with caution. They are docile but may become aggressive towards similar species of the same gender. These fish are best kept as a pair (male and female) or with one male and multiple females in tanks of at least 300 liters. They are known to jump out of open aquaria, requiring secure tank lids.
Care and Hardiness
With an average hardiness level, these wrasses need a mix of small crustaceans like krill and mysis, as well as zooplankton such as Cyclops and pods in their diet. They are sensitive during transportation and acclimatization, so special care is needed during these periods. Providing ample hiding spots among live rocks and frequent feedings are essential for their well-being.
Reef Suitability
The Filamentous Wrasse is considered reef safe, making them a popular choice for reef aquariums. Their vibrant colors add beauty to the reef environment, and they also help control unwanted invertebrates like flatworms and pyramid snails.
Aquarium Setup
Setting up the aquarium for Filamentous Wrasses should include ample hiding spots between live rocks where they can rest and sleep in mucus-covered cocoons at night. The tank should be a minimum of 300 liters with secure lids to prevent them from jumping out. Maintaining stable water conditions with pH levels between 8.1-8.4, temperatures ranging from 22.2-25.6°C, and a specific gravity of 1.020-1.025 is crucial for their health.
Behaviour
These wrasses exhibit peaceful behavior but can showcase aggression towards similar species of the same gender. Males will often display their vibrant colors more prominently, especially when in the presence of several females. Understanding their behavior and social dynamics is key to successful tank management.
Feeding and Diet
Filamentous Wrasses require multiple feedings daily, especially when newly introduced to the aquarium. Their diet should consist of a varied selection of small crustaceans like artemia, zooplankton, and other high-quality foods to maintain their health and vibrant colors.
Habitat and Distribution
These wrasses are found in the Indo-Pacific region, including the Similan Islands, Andaman Sea, Christmas Island, Indonesia, Philippines, Solomon Islands, and more. Their natural habitat consists of coral reefs where they can swim in the water column and seek refuge among rocky crevices.
