Hi all. About an hour ago when I was feeding my clowns I noticed this spot on one of them right at the bottom of the gills where the gills and body meet. Is it something to worry about? It's head also seems to be bumpy/indented on one side as well which I will include pictures of. I just so happen to have vitachem and Kent garlic on the way today so maybe that will help with whatever it is. Tank has had no new additions either for about 4 months.
