RES and other animals

Question
I have a RES and I would like to put another RES in the tank w/ it. I've read a previous question which you responded that it was ok to put another RES in the tank as long as there is enough room. My question is whether I would be able to put fish in the tank w/ the RES? Would my turtle eat or kill the fish?

Answer
RES's eat fish in the wild. If a fish is too small to be considered food, or too large, it will be ignored but otherwise it is food.

Even big fish will often get nibbled on and harassed.  

You can reduce the problem with a nice big tank, good diet, and good fish selection.
