Fish are dying

[zac15]

Many of my fish are dying in my planted tank. I attached a picture of my fish and my plants i dont understand why they are dying please help

pH- 7.4
Ammonia-0
Nitrite- 0
Nitrates-80 ppm

Is it possible my fish has nitrate poisoning?

Nitrates are really high. I'd do two 50 % water changed to knock it down to 20 ppm
What size tank. And what is your stock
I don't think the picture made it

I read that plants convert ammonia to nitrate is that true?

Plants aid the the nitrogen cycle. Mainly removing nitrates
