Harmful Nitrite?

What are potentially dangerous levels of Nitrite? Honestly I'm not concerned too much right now because I did a partial water change to this tank today and all the fish (5 flames and two bloodfins) look very healthy.

I believe that I am experiencing a mini-cycle in my ten gallon (I recently moved a bunch of flames from my 55 gallon to the ten. I was using the flames to cycle the 55).

Right now my Ammonia is 0 PPM.
Nitrite is around 1.0 PPM
Nitrate is sitting at a solid 10 PPM.

I know flames are durable little guys, which is why I chose them because if the water gets a little "eh" I can just do a slight change and not worry so much about it.

Also, what are dangerous levels of ammonia? I know around 40 is the upper end of Nitrates and you shouldn't allow it to go much farther than that. But what of ammonia? I'm guessing a very small amount, but I'd rather get a number than my guess.

Any reading of Ammonia and Nitrites are toxic. Those need to be 0ppm. No questions asked.

When I have done fish cycles, I always set my goal at keeping nitrites and ammonia under .25ppm.
How much will kill a fish, probably depends on what type fish. Some fish just cant tolerate any levels well.

low levels of ammonia and nitrite isn't as bad on a cycling tank with the same numbers. why, if you get a low reading on a cycled tank and it rids of the toxins within a 12-24 period little harm is done. but if the toxic linger around for longer periods such as a non-cycled tank the effects take a toll. the fish won't die right away when exposed to the toxins but their days can be numbered. as far as nitrates. 40 is high. you want to keep it lower than 20 or so. if you have plants, it helps a lot. i am struggling to keep 5ppm in my tank so i will need to dose nitrogen in order to raise the nitrate level.

You can just come over to my house and take some of my tap water home Flight50! I will not even charge you!
I have anywhere from 20-40ppm nitrates in my tap water. I only wish I had your problem!
I am fighting to keep my nitrates under 80ppm in my tanks.
Maybe I can start bottle it up and sell it as a cycle starter!
