How to treat these?

It's not a yellow coris. Not even a coris type wrasse at all. Bad evil common name :hammer:

Yellow wrasse, or Canary wrasse are more appropriate. Or call it by it's scientific name so that anyone can google it and come up with the same fish.

Good wrasse choice They do like to sleep in the sand at night so have an 1" at least of fine sand for it to dive into :thumbsup:

funny thing about that fish is everybody knows what you are talking about when you call it a yellow coris or a golden coris

I have 3 of them that might disagree with your needing sand theory

I know about the coris thing. Thing is if everyone broadens their knowledge, maybe it'll get a proper name. Fish stores are a good place to start.

Ok, it's natural and best for them to have the sand When I added my Melanurus to my qt he kept trying to bury in my glass until he found the sand container I placed in there for him. Hid for almost a week.

No worries, I have plenty of sand for him. Gotta have it for my jawfish or he would be one unhappy camper.

melanaris (sp)dont need sand either

have two of them

I have had just two supposedly needing sand fish so far I havent been able to convert.........a leopard wrasse and a pink spotted watchman. Had to find them new homes after giving it enough time that any more was going to endanger them.

Make sure to calibrate your hydrometer with a refractometer. Find someone locally or go to your nearest local fish store. These have been known to fluctuate a lot.

I verified it is reading the same as my LFS and their refractometer read the same as my hydrometer. I'm hoping the sixline wrasse will start working his magic in the tank. I'm also going to get a yellow wrasse.
