Hey guys and gals, I was just recently giving my fish tank a water change vacuuming the gravel etc. Once I finished with all that I decided to just stare at my fish to see how they were doing making sure nothing was wrong and I noticed one of my red platys went close to a rock I have and tried to scratch himself on it. I think I also saw my panda platy do it too , I've just recently started reading on ich to see what I can do to stop it but by the looks of it I can only kill the free swimming ones. I was wondering if any of you guys have any advice on what to do. First time I've had this problem and I want to make sure I do it right! Thanks!
