Pink Streaked Wrasse – Complete Care Guide

    The Pink Streaked Wrasse (Pseudocheilinops ataenia) is a beautiful species of wrasse with various pink, orange, and blue colorations. As its name suggests, the Pink Streak Wrasse has horizontal “streaks” throughout its body. They’re a very peaceful fish species and are generally easy to care for. This guide will dive deeper into the Pink Streak Wrasse’s aquarium requirements, dietary needs, tank mate compatibility, and breeding.

    Aquarium Requirements

    Sometimes called the Pink Streaked Pygmy Wrasse, this fish species is an excellent choice for many different saltwater aquariums, including nano fish tanks because they only grow to 2.5 inches. I recommend keeping them in 20 gallons or larger aquariums, but if you have plenty of saltwater experience, they can thrive in reef tanks as small as 10 gallons. I also recommend providing them with plenty of live rock of different sizes because they are often very shy when first introduced into the aquarium.

    Many wrasses are known to jump out of the fish tank. That’s no different with the Pink Streaked Wrasse. I recommend a well-fitted lid to prevent this from happening.

    Water Paremeters

    Having stable water parameters is an important aspect of keeping a successful saltwater aquarium. The following are water parameters this species does best under.

    • Water Temperature: 72°-78° F
    • dKH: 8 – 12
    • pH: 8.1 – 8.4
    • Salinity: 1.020 – 1.025 sg

    Consider getting a High Range pH and KH test kit to test for pH & dKH. Keeping your temperature between 72° and 78° can be accomplished with a heater. Take a look at my guide which showcases some great aquarium heaters. Lastly, I would pick up a Refractometer from Amazon to keep an eye on your salinity levels. If calibrated correctly, refractometers are much more accurate compared to a hydrometer which loses accuracy due to salt buildup on the dial. Check out Different Salinity Reading Tools For Saltwater Fish Tanks to get an idea of other salinity testing devices available.

    Are Pink Streaked Wrasse Reef Safe?

    Pink Streaked Wrasses are reef safe. They should not bother any desirable coral or invertebrate in the aquarium. You will often see this species of fish weave in between different kinds of coral, but it will not bother them. They may nibble on nuisance inverts like bristleworms and flatworms.

    Food & Diet

    This species is carnivorous, so they will need a protein-rich diet. A good source of protein will be Mysis Shrimp, Brine Shrimp, and other meaty foods found at fish stores. I recommend giving them pellet food as well, to provide a well-rounded diet. For pellet food, the New Life Spectrum Marine Formula is a good choice, but many different brands can be used. Lastly, it never hurts to provide flake food for this wrasse.

    Tank Mates

    Pink Streak Wrasses are very peaceful. They will mostly mind to themselves and are more likely to be picked on by other fish due to their docile nature. They’re amazing for community saltwater fish tanks. They will do great with fish like Clownfish, Chromis, Gobies, Cardinalfish, Butterflies, Jawfish, Dwarf Angels, Tangs, and Blennies. I would be a little cautious when adding them with fish that use the same space in the aquarium, like Dottybacks and other Wrasses.

    I would not recommend them with predatory fish or fish that get incredibly large. Keep them away from Eels, Triggers, Groupers, Large Angels, Anglers, and many other types of large aggressive fish. They will either get picked on or become food for the large fish.

    Breeding

    I have never bred this species of fish before, but I have read that fish keepers have kept them in small groups. There is not much information on successfully breeding Pink Streaked Wrasses, but you can distinguish between males and females fairly easily because they are sexually dichromatic. Males will have more vibrant streaks of yellow and the females will have a blue coloring over their gills. Regardless, of being able to distinguish between male and female, I feel like the Pink Streaked Wrasse, like many other saltwater fish will be incredibly difficult to breed successfully in a home aquarium.

    Final Notes

    There are a lot of different species of Wrasses available in this hobby. The Pink Streak Wrasse is considered one of the best for reef aquariums. They have gorgeous colorations and are incredibly peaceful. If you’re setting up a nano reef, consider getting a Pink Streaked Wrasse. If you are not sold on this species, check out other reef-safe Wrasses available in this hobby. It is a growing list of species, so stay tuned for future updates.
