So I think DD's fish has a fungus on his eye. He lives in a ten gallon tank with live plants, a few corys, ghost shrimp, and a snail. I have heard that medication is not good for invertebrates, so I was going to put him back in his old 1 gallon tank for treatment. BUT...all of the fungus medications I saw today (and I checked THREE stores), are for treating 10 gallons of water. And they are tablets, so it seems like it would be hard to break it apart into the right dose for only one gallon? Any suggestions?
