Do all the Terrapins/Turtles get on with each other, do they fight?

All the Turtles get along just fine with each other. We make sure to provide them with enough space to move around and get away from each other if needed. Turtles can show signs of aggression if they feel boxed in and too crowded. If we do see an aggressive turtle it gets removed from the pond and is housed separately in isolation.
