Sure they are - bred many Rams, Apistos, Discus, lampeyes, Tetras, Rasboras, or even shrimp lately? Got any six year old Neons or Cardinals? Fifteen-plus year old Africans? Yeah, harmless, sure.
A bunch of Vietnam vets came home and "looked great" for decades before developing sickness from "agent orange", too! Just because we don't see our fish pale and visibly wasting doesn't mean they aren't slowly being worn down by toxic waste. There are many fish in the rivers around here too, and I know what kind of garbage gets put into the water.......very polluted waters to say the least!
Of coarse just because someone keeps under 5 ppm nitrate in their tank doesn't mean the fish doesn't live in polution of some sort. The question was "at what level does nitrate become toxic?"......so here is the answer: .1ppm !!!
The solution is to keep your tank in the cleanest condition you can. Watch your fish, change water frequently, quarantine, etc. You can not stop pollution from accumulating in a glass box.....it is going to happen. Minimalize it as much as possible, but don't turn what can be fun into a demanding choir that is impossible to keep up with. Just remember that living and surviving are two different things!

I never told him to keep it at 50 - 100 ppm, I just told him what he wanted to know: nitrates usually won't kill fish until after that range (of course it depends on the species). I never let my nitates get that high and i never recommend anyone to.

Self explanatory, self-contradictory, and very poor advice IMHO & IME.
When we post on these boards, we need to think of what will happen if the questioner actually follows the advice given. The first statement certainly implies that 50-100ppm nitrate is acceptable.
