That's why I don't think bb need very much more than above 0 ammonia to grow. Especially as a cycled tank will show as 0.
I've noticed neons look sulky at about ph of 7.5 and ammonia of 1 so I think sometimes we are dealing with averages. On average something may be fine but eg you may have sensitive fish.
