maybe check the temperature is right?
also I found on my wooden floors they don't like the vibrations
I cause when walking around the tank when they were juveniles.
Also it could just be the sudden change in the enviroment,
or they could be bloated.

hope this might help

cheers

I just purchased a pair of young red oscars. I set up a 10 gallon tank
only for
them. They are apparently frightened and are immobile at the bottom of the
tank. They refuse to eat. This has happened in the past with oscars. How
can I
get them to become active?
