i did let the water cycle for about a week and a half before i put them in i gave them feeder fish an sunday they didn't eat them and they have been in the tank ever since i was not sure if they were causing the proble but i just took them out
Without adding a cycled filter or old media with the good bacteria your tank will take anywhere from 45-50 days to cycle...
If in fact you are cycling with your oscars in that tank, you could end up in a serious mess. Do you have somewhere else for the fish to go? Can you take them back to the store? They will have serious health problems if left in an uncycled tank... How long have you had these fish?
