Mom's worried about her black moor again: it's been fairly lazy lately (which I always blame on the 10gal tank it's crammed into). Whenever it acts this way, it gets little soft-looking white spots on its fins. It's not ich, which has sharply-defined edges (from what I've seen in LFS tanks). The edges of these spots are a little blurry. Mom says it's worse this time than usual; she sees spots on its sides as well. I just had to talk her out of trying some random anti-fungus meds, at least until we know more. Any thoughts? I don't know if it's a disease, if it's caused by inactivity, or if it's CAUSING inactivity. Any suggestions would be great.
