Really high! For a length of time. Probably not nitrates.

I've been battling with high nitrates myself and I can tell you clowns can be very hardy and high nitrates are not gonna get to them at all, well for a short period of time though. If you keep high nitrates for a long period of time, not only clowns will be affected but all other fish as well.

How long did you guys have the clowns? Its pretty strange both clowns died at the same time. As i said before, those little guys can be and are pretty hardy, they can take a lot of abuse if they are healthy. My guess is they were already sick from before.

We have had the clowns since late October. Like I said they were healthy,eating well and very tame. They started acting strange one day and the next day they were dead.

They just quit eating.

The odd time this has happened to me was after I left frozen food on the counter for a few hours... Then used it. Go bacteria!
