About the Yellow Coris Wrasse

The Yellow Coris Wrasse is known to the aquatic community under various names: golden rainbowfish, golden wrasse, yellow coris, and canary are several names that you will see. Its scientific name is Halichoeres chrysus and it hails from the Pacific Ocean to the edges of the eastern Indian Ocean. In the wild, they can be found in areas around 60 to 200 feet deep.They are known for grouping together in all stages of life and young wrasses and be identified with the one or two spots they have on their dorsal fin. 

Yellow Coris Wrasse in the Aquarium

Below are the main stats for the Yellow Coris Wrasse:

  • Minimum Tank Size - 40 Gallons
  • Max Size - 5"
  • Temperament - Peaceful

The Yellow Coris Wrasse is best known for its ability to eat a number of nuisance pests in the aquarium. Really they well eat just about any pest in the aquarium except for aiptasia.

They will eat nearly any type of meaty food offered to them and do not get too large with the max size usually being around 5". They are one of the more docile wrasses in the Halichoeres genus and are model citizens in your tank. They not aggressive towards other fish and nor are they particularly territorial. They do prefer a sandy substrate as they are known for burying themselves. Keep this in mind if you are thinking about a bare-bottom setup. They are a fairly hardy fish and a good choice for a beginner.

The great thing about the yellow coris wrasse is the availability of tank bred varieties. They can be easily found tank bred either online or locally. The tank bred varieties tend to be hardier, drama free, and also help preserve the wild reef environment. Whenever a tank bred variety is available I always recommend the tank raised fish over the wild caught one. 

The main issue with these fish are their tendency to jump out of the tank when stressed. It it recommended that you cover your tank with a mesh screen  to prevent any accidental fatalities.  

Are They Reef Safe?

Yes, they are reef safe. I have seen reports on forums where they have eating corals or disturbs other inhabitants, but I feel a lot of these issues are mostly due to not having the fish feed well or lack of space. That being said, all fish have different personalities and you could get a yellow coris wrasse who's personality is not the norm. The best way to prevent any tank drama is having the right tank, having them well feed, and purchasing a tank bred specimen.
