Hello everyone i have a little problem with one of my fish in my bio cube 14 last week i was so dumb that i purchase a royal gramma from petco and now I see it scraping his body on the rocks for the last couple of days and now I see all kind of white spot on his body. I am worry about my tank having a ich breakout because I have a clown and a firefish that have been in the tank for more then 4 month. Please help
