Hey everybody,
I noticed when I was feeding my fish this morning that my black molly (approx. 1 yr. old, born in my tank, no previous issues) has a large white spot on her right side by her fin (definitely not ICK) and also on the same side it looks like she has a lump under her skin

She is eating and swimming normally, not appearing sick at all......I just happened to notice it. Does anyone have any advice/opinions on this? I look at my fish very closely, so I don't think it is something i would have missed before?? Appreciate any replies, hate to see any trouble starting in my tank.
Thanks, Frosty
