What Six Line Wrasse look like
The Six Line Wrasse (Pseudocheilinus hexataenia) exhibits a strikingly vibrant coloration characterized by six distinct horizontal blue lines that run along its elongated, laterally compressed body. Adults can reach a maximum size of approximately 3 inches (7.6 cm). Sexual dimorphism is subtle, with males typically displaying more intense coloration and slightly larger body size compared to females. This species possesses a robust set of dentition adapted for feeding on small invertebrates, and its dorsal fin is elongated, featuring 9-10 spines and 12-14 soft rays, which aids in agile swimming. The lateral line is well-defined, providing sensory capabilities to detect water movements and potential predators, while the overall body shape is streamlined, enhancing its swimming efficiency in reef environments.
Behavior & temperament
The Six Line Wrasse is known for its active and inquisitive behavior, often found darting among rock crevices and coral formations. It exhibits a social hierarchy, typically establishing territories within a reef environment, where dominant males display aggressive behaviors towards intruders. Breeding occurs in pairs, with males engaging in courtship displays that include color changes and fin posturing. This species is generally considered semi-aggressive, particularly towards similar-sized wrasses, but can coexist peacefully with a variety of reef inhabitants when provided with adequate space and hiding spots.
Diet & feeding
In the wild, the Six Line Wrasse primarily feeds on small crustaceans, zooplankton, and other small invertebrates. In captivity, it requires a varied diet that includes high-quality pellets, frozen or live foods such as brine shrimp, and mysis shrimp to ensure optimal health and coloration.
Behind the name
The genus name 'Pseudocheilinus' derives from Greek, where 'pseudo' means false and 'cheilinus' refers to a type of wrasse, indicating its resemblance to other wrasses. The species name 'hexataenia' comes from the Greek 'hex' meaning six and 'taenia' meaning band, referring to the six distinctive stripes on its body.
