Ok my O. Clowns just started this 3 days ago. As of yet I have not seen any ich. They flash on my filter intake tube and they also jerk their heads side to side. This cant be normal. They only new addition is my cleaner/skunk shrimp who does clean my pink spot goby but the clowns havent let him yet. Water parems are.....Ammon 0 nitrite 0 nitrate 10. Live and argonite live sand. Heat set to 78 F. Could this be the beginning of ich or something else ?
