It sound like your WW clownfish is a female, not a male. If your looking for a mate. Make sure your buying a male because 2 female will fight to the death.
Getting rid of the WW clownfish is not a solution!
There are several ways to pair a female and male which I have tried in the course through the years with clownfish.
But firstly, purchase a small male of your choosing. Secondly, put both female and the new clownfish in a small diy container with holes that you can hang on the inside of the tank, or a breeder net. Should be small and that it will fill half way of water. This way the clownfish don't have room to swim away from each other. There will be a little fighting, keep them in the container for several hours from 3-6 hours the longer the better. Release the male in the tank, and leave the female in the container for a couple hours. Your putting the female in "timeout", because she doesn't no how to behave..lol
Then release and observe how they interact with each, there might be a little fighting. If it gets to abusive repeat the container method again. However, it should work the first time. This is what work for me. Here's a picture of my container DIY made of acrylic. A longtime friend in the hobby made this for me it was intentionally for the use to hold frags.
Good luck and let us know with pictures on how it went.
