Tonight I noticed that my clowns had some black spots on them that almost looked like pepper. I didnt notice anything like that yesterday. I removed them from the display tank and put them in QT. While acclimating I did some research on what this was and treatments. Treatments consisted of a "freshwater dip" and or a fomalin dip. I had no Formalin and all the stores was closed so I did a freshwater dip . Has anyone ever had this with there clowns and what methods was used ? they seem to be doing good as in eating and were still trying to be the king and queen of the tank.
