I found the biggest promblem was water quality. I kept a soft shell with a bunch of silver dollars without issue except for water quality due to the turtle.

I am trying it with my small turtle and a couple of large Dempseys. It's been working well for a good while. Water quality is the hardest thing to keep up with. They all eat the same food even.
Op hasn't been around since December. Don't think replying to a 5 year old post will help that much....1. Turtles are super dirty. 1 of your challenges is your water quality upkeep. If you stay on top of weekly 20% water changes that's a good start.
2. You gotta allow for plenty of room for the fish to swim away from the turtles in case they're being chased and harassed by the turtles. Whatever tank you have, keep the livestock to much less than you would with a fish only tank.
3. Allow of hiding areas that the fish would fit through, but not the turtles. I have used pvc pipes in the past. They're great and cheap.
4. As a bunch of people mentioned, turtles are a hit and miss. Some are a total pest, and some are really mellow.
5. I've had cichlids with good luck with my turtles, just make sure they're at least twice as big as the size of their mouth. In general, I recommend getting fish that are able to move in an explosive way.
6. Use a reactor and stay up with carbon replacements. Their poop tends to wanna make water murky, and carbon helps to get rid of that.
7. Create a bunch of water current in the tank. Turtle poop is dense and just drops to the bottom of the tank.
8. Make sure to siphon the gravel during water changes.
Hope all this helps.
