Rotating an isometric enemy to face the player.

Hey guys probably a really silly question but I’m currently making my HSC major work for my software class and I cant for the life of me face my enemy ships at my player.

Here is a video of the problem life-like enemy crab movement - YouTube
and here is my scripting:
using UnityEngine;
using System.Collections;

public class EnemyScript : MonoBehaviour

public Transform target;
public float speed;

void Update()
    // rotate the enemy ship to face the player ship
    //correcting the original rotation
    transform.Rotate(new Vector3(0, -90, 0), Space.Self);
    //me struggling to get the ship to face the right way ( unsuccessfully)
    transform.localEulerAngles = transform.eulerAngles + (new Vector3(0, 0, 0 * transform.eulerAngles.x));

        transform.Translate(new Vector3(speed * Time.deltaTime, 0, 0));
