when i left to work everyone was ok, i come back and 1 my balas was laying dead.. on top of the sunken ship!! no fish was close to him no nipping everyone was far from his dead body, i pulled him out and he had no sings of fungus or scars. his body was just hard as a rock!

I WONDER WHAT COULD OF HAPPENED?
pH: 7.0
nitrate: 20
amonia: 0
nitrite: i dont know i dont have the tester!
Question: do you guys think the a high level of nitrite can be deadly

?
im getting the nitrite tester tomorrow asap!
i recently did a 30%
water change for the past 2 days in a roll since i started to see that my nitrate level started to raise. the levels were ok today.

i dont flush my dead fish. he was properly buried in one of my plants pots see if his dead body helps my plants grow healthy!! here is the plant!!

R.I.P little bala swimmer
does anyone have any idea what could of had happened

?
thank you for your time!!!
