Rainbow shark and oscar?

Question
Hi Ron,
Can you keep rainbow sharks with oscars in a 125 gallon tank? Can you keep
discus with oscars?
Could my 5 discus live in a 40 gallon bare bottom tank with 50% daily water
changes?

Thanks a bunch!

Answer
Hi William,
 You can put almost anything you want with an oscar, and the oscar will probably eat it.  It might not happen today, or tommorrow, but eventually I can pretty much guarantee that if the oscar can fit a fish in its mouth, it will eat it.  That's what oscars do and they are extremely good at it.

 Yes, your discus could live in a 40 gallon bare bottom tank with 50% daily water changes.
