I just changed Copernicus's water again tonight, and while watching him in his cup, his dorsal fin seemed to bother me a bit. I've added pictures below, and he has stress stripes because he always freaks when it's water changing day...as soon as he's back in his tank they go away. Also, the edges of his dorsal fin have always been discolored, but I'm not sure if th raggedness is fin rot?
