I have 2 three inch iridescent sharks that about one week ago developed a white spot on the very top slighty behind the eyes. Both sharks developed this spot at the same time, in the same place. No other spots on the sharks or my clown loaches. I bought Ich Remover and used it at half strength because I have heard both sharks and loaches are very sensitive to this. 2 24 hour treatments with 25%water changes in between and water at 82 degrees as per directions. Any additional information would be much aprreciated because I love these lil guys. Is there a chance it is not Ich? These sharks do not develop this spot for some other reason do they? Thanks in advance...Brian
