The Neon Line Wrasse is one of the easiest wrasses to identify in every colour phase. Adults have a golden to yellow head, a black vertical bar behind the tip of the pectoral fin, merging with a broad black area on the upper side, continuing to the top of the caudal peduncle and upper caudal fin and blue underneath. Juveniles are yellow with a turquoise-blue stripe along their sides. This colour-changing characteristic makes the Neon Wrasse a fun and fascinating fish to observe in your marine aquarium. The Neon Line Wrasse is a reef-associated species, common on shallow and deep reefs as well as rocky ledges.
The ideal setup for the Neon Line Wrasse will be a well-filtered, established saltwater aquarium of at least 75 gallons in size with a tight-fitting lid. To best recreate a natural reef environment for your Neon Line Wrasse, aquascape liberally with live rock, providing ample nooks and crannies for your Neon Line Wrasse to explore, seek refuge, or forage for food. Be sure to include a large area of open substrate as well as open spaces for swimming. A sandy substrate layer 2-3 inches in depth is essential to provide shelter for the Neon Line Wrasse as it burrows into the sand for the evening or when frightened. House the Neon Line Wrasse with other peaceful wrasses, including members of its own species. The Neon Line Wrasse is peaceful towards other fish, but are territorial, bordering on aggressive with conspecifics, so it is best to keep one Neon Line Wrasse per aquarium.
The natural diet of the Neon Line Wrasse consists of benthic invertebrates and as such, large, hungry Neon Line Wrasse will eat fireworms and pyramidellid snails, protecting corals and clams from these undesirable invertebrates. The Neon Line Wrasse may also eat parasites off of tank mates. Though this hearty appetite for invertebrates seems beneficial, keep in mind that the Neon Line Wrasse cannot differentiate between "undesirable" and "desirable" invertebrates. If the opportunity presents itself, the Neon Line Wrasse will most likely make a meal of "desirable" ornamental invertebrates including fan worms, shrimp, and other crustaceans in the home aquarium. However, the Neon Line Wrasse typically will not harm sessile invertebrates including soft or stony corals.
In the home aquarium, the diet of the Neon Line Wrasse should consist of a diverse variety of food items including vitamin-enriched frozen mysis shrimp, vitamin-enriched frozen brine shrimp, and other meaty foods along with high-quality marine flakes and marine pellet foods. The Neon Line Wrasse will benefit from frequent small feedings throughout the day.
