Hello. I have a 15 gallon with 6 platies in it. One of my platies started showing signs of ich so I started treating with paraguard about a week ago. (My heater doesnt have a temp control on it to change temp.) The ich seems to be getting better but I have 1 platy that has had her fins clamped for a while now. She isnt showing signs of ich or infection. No redness No swelling still eating etc. I have tested my parameters and they came up as ammonia 0, nitrite 0, nitrate 0. I use the api freshwater masterkit. Temp is 76. Weekly 60% water changes during treatment. Carbon removed, but bio media still in place. What am I missing?
