Reef Compatibility of the Rainbow Wrasse

Rainbow Wrasses are generally not considered reef-safe and can be kept in reef aquariums with caution. They help control pest populations such as bristle worms and pyramidellid snails.

These wrasses typically reach sizes of 4 to 6 inches in captivity. With proper care, Rainbow Wrasses can live for several years, with lifespans averaging 5 to 7 years.

Diet of the Rainbow Wrasse in Captivity

Rainbow Wrasses are carnivorous and should be fed a varied diet consisting of high-quality marine pellets, frozen foods, and live foods. They readily accept offerings of brine shrimp, mysis shrimp, chopped seafood, and marine-based flake or pellet foods.

Compatibility of the Rainbow Wrasse with Other Fish

Rainbow Wrasses are generally peaceful and can be kept with a wide range of tank mates, including other peaceful fish species and invertebrates. However, they may exhibit territorial behavior towards other wrasses or fish of similar size and shape.
