Sixline Wrasse

How to Care for Azure Damsel
written by Dave Burr

The Sixline Wrasse will capture your attention as it swims effortlessly throughout the aquarium. It requires an established reef aquarium with plenty of live rock and live sand. The Sixline Wrasse feeds primarily on micro inverts living in and around the live rock. Systems with refugiums offer this fish an added source of live food.

The Sixline Wrasse is harmless to ornamental invertebrates, clams, and coral. It will help to control pyramidellid snails, which are harmful to clams, flatworms, and bristleworms. It may behave aggressively towards smaller wrasses and gobies. Do not keep it with aggressive predators or larger aggressive wrasses.

Keep a lid on your aquarium because the Sixline Wrasse is very likely to try to jump out.


Offer the Sixline Wrasse a mixed diet of mysis shrimp and finely chopped meaty foods 4-6 times per week. Soaking all fish food with vitamins will help keep your fish healthier and make them less susceptible to disease. We recommend soaking food in garlic as well when adding new fish and whenever your notice ich or other disease in the aquarium. Garlic will help repel external parasites and will boost the fishes immunity.

Feeding Tips:

Remember to feed slowly. Leftover food will cause nitrates and phosphates to rise. If you see food falling to the sand bed and into the rocks you should feed slower and give the fish a chance to eat before adding a little more. Using a turkey baster allows you to target food to different fish. For example you can feed the aggressive fish on one side of the tank and then squirt a little bit on the other side for the less aggressive fish. This way all the fish get a chance to eat enough.

Fiji, Indo Pacific
Water Conditions:

75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppm

Water Chemistry:

Maintaining Ammonia at 0 ppm, Nitrites at 0 ppm, and Nitrates below 10ppm will help to keep your Sixline Wrasse happy and healthy. We recommend doing a water change soon after Nitrates rise above 10 ppm. Maintaining proper calcium (420-440 ppm), alkalinity (8-9.5 dkh – run it 7-8 if you are carbon dosing), and magnesium levels (1260-1350 ppm) will help to keep pH stable in the 8.1-8.4 range. We recommend a specific gravity of 1.024-1.026 with 1.025 being ideal for fish. Temperature should remain stable as well and should stay within a 2 degree range.
