KayAnn--

Whenever my fish get sick, I use Binox. In my opinion this is GOOD STUFF. It is made by the Jungle company (some people don't like their products) but I've never had any problems with them.

Binox is a bacteria and fungus rememdy. It can be used to treat fungus, grey slime, flashing (aka scratching), and open sores.

It's POWERFUL stuff--one teaspoon to 25/gal of water. Becareful how much ya put in there!

You might not be able to get this from Walmart--you might have to check out a couple of pet stores. If you have trouble finding it, let me know.

Good luck!
