The general rule suggests one turtle per habitat. However, in my opinion, hostile aggression over territory depends on more than just having two turtles in close quarters. Of course, having a larger habitat will provide more room for multiple pets, which may cause less aggression. Also, the question you should be asking might be whether the two turtles are same gender or not. I don't know what the specific living arrangements may cause for male-male, female-female, or female-male, but I'm sure you could search it or somebody will tell you after this. In my own experience, I've had tank with 4 RES in a 20g tank, and I now have 2 RES in a 55g tank. In my opinion, 4 of any pet might be too much, except maybe fish and insects. Especially in a small space, 4 was WAY too much. However, the 2 RES I have now live perfectly well. I DO NOT feed them at the same time in the same space, that is the time when the bigger RES does not care for the other RES and it just goes for the food. Also..for some reason, I think having two RES in one tank stunted their growth. I feed them good lettuce and good mix of pellets, and separately too, but they just don't grow as rapidly.
So, basically
1. More turtles = more of everything
-space, filtration, food, ultimately money
2. Feeding time = Aggression
3. Gender matters
