That looks like a 30 or 40 gallon... Too small for that population. A 55 to 75 gallon will do just fine.
I think your turtles need things to do. Try adding in an air stone, or some ping pong balls, and definitely artificial plants. Anything they can actively move around will give them other things to do besides argue. With a lack of space and being relatively bored, turtles will quarrel.
If that doesn't work, separate the middle one from the others. The middle one will eventually get on the bigger one's nerves, and the bigger one is old enough to cause some serious damage.
