Nice Oscars everyone!
A 55 gallon tank is too small for an Oscar. They need a 75 at minimum. A 55 is barely 13 inches deep and an O will grow to more than that and will have a difficult time turning around if at all. They have been known to get to 14-16" big in an aquarium setting.
As far as not liking change - I know mine doesn't and gets moody and sometimes turns his back on me and gives his tail a vicious shake as if to ell me he ain't a happy camper! LOL
