What's wrong with my fish? :(

    About a week ago, my tank finally finished cycling with fish after about six weeks. The readings were 0, 0, 10 (ammonia, nitrite, nitrate).
    Last night when I did my regular feeding I noticed that one fish had a few black streaks on it's fin. A few others also had these black streaks on their fins, about 1-3 mm long. I immediately did a water test and it came out to 0, 0, 40 (ammonia, nitrite, nitrate).

    I know black streaks are a sign of ammonia poisoning, but the funny thing is I have 0 ppm of ammonia and nitrite. My ammonia lot bottle #'s are 83A0409 and 84A0509, so I think that they haven't expired yet. I know my nitrates are a little high, but honestly I don't think that is creating the black streaks. Besides the black streaks, everything else seems to be fine and normal. I'll be doing a 30% water change in a couple hours.

    Help! What should I do? Should I add a little zeolite in the filter bags?

    If they were in the tank while it was cycling, they were already exposed to ammonia, even if there isn't any in the tank now.

    Agreed, they may just be showing effects from cycling.

    So should I worry about the streaks?
