Common name: Smalltail wrasse

General information

The Pencil Wrasse, scientifically known as Pseudojuloides cerasinus, is a slender and vibrant species of wrasse that adds a splash of color and activity to any reef aquarium. This species is known for its elongated body and striking coloration, which typically includes a bright pink or magenta streak along its greenish-blue body. Males often exhibit more intense coloration and may develop elongated finnage as they mature.

Care

Pencil Wrasses are active swimmers and require an aquarium with plenty of open space to roam, as well as rockwork or coral formations for hiding and sleeping. They are generally peaceful but can be territorial towards other wrasses. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

In the wild, Pseudojuloides cerasinus are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life. In the aquarium, breeding is less common, but providing a stable environment with multiple individuals may encourage natural reproductive behaviors.

Habitat

Pencil Wrasses are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They typically inhabit coral-rich areas and lagoons, often at depths ranging from shallow waters to about 30 meters. Their natural habitat includes a mix of sand and rubble substrates where they can forage for small invertebrates.
