i had to change my oscar to a bigger tank and since i put him in he is lying on bottom of tank i hope he is ok

likely hes just moody. give it some time and monitor your water closely.

Some creatures do play dead but I don't believe Oscars will do this. Water changes can often be quite a traumatic time. You should be checking to make sure there isn't too much of a fluctuation in water temperature. Not too much disturbance when the water goes back into the tank. It is not uncommon for a Oscar to behave strangely after a water change. However, this behaviour shouldn't carry on for too long. If it does, the first thing to do is the water test as has already been suggested.

He is doing that because he is being a cranky ass... lol Give him some food and he should come out of his slump...
