It is possible that the Oscar got spooked in the middle of the night and hit the lives of the tank. Or maybe if he could see was jumping at a drip thinking it was food. As long as your arm only a nitrite remain at zero in your tank is cycled. Whereas a nitrate reading of Zero is virtually impossible, if you have carried out our water changes in your my traits may be low. Just keep a check on the ammonia and nitrite and make sure they don't rise above zero. Obviously if something goes wrong and some of the bacteria dies then that will obviously upset the whole biological filter.

thank you for ur help u can close this
