Some of my neon and glow light tetras, mollies and sword tails gills are moving rapidly. And some of them have the jitters. The rest of my fish which include danios (strawberry and zebra), platys,cat fish and brazilian sucking loaches are fine. I noticed 1 mollie had white spot today and put some anti white spot in the tank. I didnt notice if the gills were moving rapidly before i added the medication or no. Please help
