unity - Enemies are penetrating in each other when following player

As you can see the image my enemy (when following my player), penetrate each other. How can i avoid it? I am using NevMeshagent to follow the player.

void Update () {
    currentNavMeshAgent.destination = player.transform.position;
}

I have added a Rigidbody and a Collider to my enemy object but they are still penetrating each other

Answer

To avoid penetration, increase each NavMeshAgent's radius so it's equal to or larger than your agent's collider.
