Turtle community tank?

Hi everyone I'm new here.
I've had a bunch of different turtles for years now and have always kept them in species specific tanks. Could you make a community turtle tank? I would want to include my favorite types like soft shells, chicken turtles, painted turtles and musk. I also like snapping turtles but I know you can't mix them together. Any advice would be greatly appreciated.

You can, yes, but community stuff for turtles is better achieved in a pond than a conventional tank. Space and varied niches can be key. Babies can be easy enough to mix in a tank if the needs of various types are met, but they grow up. Also, something like a soft shell turtle might be more likely to take snorkel and shell margin damage from crowding with another animal, same species or not.

I have done this in both tanks and ponds. You have to be ready to remove problematic individuals if they are or become behaviorally incompatible with their cagemates.

I have a fly river turtle with a stinkpot musk and they get along fine.
