Excuse me for talking about my fish's poop on the forums, but I know it can be a good indicator of illness.
Fishnu's poop this morning is white and stringy, hanging straight down, not his usual orangey curly thing. I just read in another thread that this could be a sign of internal parasites.
He is otherwise healthy, no discoloration, he is active and eating.
He is in a 1 gal heated unfiltered tank with daily 100% water changes. I just tested his water and all parameters are perfect except nitrates, which are up at 2.0.
I am preparing water for a water change right now, but does anyone think I should start treating him for parasites (and how?) or should I see how he does with a water change?
