Well,
For comparison
I have a 75G w/ one oscar (8 inches), 1 Pacu (9 inches) and a full grown dempsy pair
And we are setting up another large tank to house the pacu by himself. (our oscar and dempsey pair have been quite abused by said pacu), Pacu are a whole other issue, so lets gowith what you have,
A full grown oscar should have at least a 55G for him/herself. So I could guess that you have an over population problem. Plus oscars are dirty dirty fish, eat allot and releive themselves allot. You may want to invest in a fluval 403 or 404 canaster filter for your 55. Plus maybe giving up a few fish, or you could upsize.
Hope I've helped some
Thanks
Rusty
