How to Care for Green Wrasse

written by Dave Burr

Behavior: The Green Wrasse requires an established aquarium with plenty of live rock and live sand. This is a very peaceful wrasse and can be housed with a wide variety of docile reef fish including other small wrasse.

The Green Wrasse is a great reef fish and is often seen cruising all over the tank looking for food. It will help to control pyramidellid snails, which are harmful to clams, and flatworms. The Green Wrasse is harmless to coral, clams, and invertebrates. Do not keep it with aggressive predators or larger aggressive wrasses as it can be easily intimidated.

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

Feeding: Offer the Green 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.

Maximum Length: 8"
Care Level: Easy
Family: Labridae
Reef Compatibility: Good
Minimum Aquarium Size: 70 gal.
Range: Indo Pacific, Australia
Diet: Carnivore
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 Green 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.
