The ideal setup for the Yellow Wrasse will be a well-established saltwater aquarium of at least 50 gallons in size with a tight-fitting lid. To best recreate a natural reef environment for your Yellow Wrasse, aquascape liberally with live rock, providing ample nooks and crannies for your Yellow 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 Yellow Wrasse as it burrows into the sand for the evening or when frightened. House the Yellow Wrasse with other peaceful wrasses, including members of its own species.
The natural diet of the Yellow Wrasse consists of benthic invertebrates and as such, large, hungry Yellow Wrasse will eat fireworms and pyramidellid snails, protecting corals and clams from these undesirable invertebrates. Though this hearty appetite for invertebrates seems beneficial, keep in mind that the Yellow Wrasse cannot differentiate between "undesirable" and "desirable" invertebrates. If the opportunity presents itself, the Yellow Wrasse will most likely make a meal of "desirable" ornamental invertebrates including fan worms, shrimp, and other crustaceans in the home aquarium. However, the Yellow Wrasse typically will not harm sessile invertebrates including soft or stony corals.
