Hey guys,
Did a water change a day ago(not sold on this being an issue yet) and noticed my foxface isn't doing too well, she is staying closer to the top and seems to have a scar closer to the tail, with some wite flakes around it. I am not sure what this is exactly, and what I should do. Can anyone provide advice?
