Unity Prefab spawn incorrect rotation - unity3d

Question

I have the following simple prefab:
When I add this to my scene, it looks like this:
Very neat!
Then I have the following script on my Character:
public class MageController : MonoBehaviour {
public GameObject Spell;
public float SpellSpeed;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetKeyDown(KeyCode.H)) {
GameObject newSpell = Instantiate(Spell);
newSpell.transform.position = transform.position;
newSpell.transform.rotation = Quaternion.LookRotation(transform.forward, transform.up);
Rigidbody rb = newSpell.GetComponent<Rigidbody>();
rb.AddForce(newSpell.transform.forward * SpellSpeed);
}
}
}
The goal is of course to make sure that the fireball is spawned correctly (with the tail behind it)
This works when I stand at 0.0.0; it looks like this:
However, if I turn around it looks like this:
As you can see, the rotation of the fireball is not correct (in the above incorrect image it is flying away from me, however, the tail is in front).
What am I doing wrong? How can I make sure that the tail is always correctly placed?
Update after following the guidance of PlantProgrammer
it still turns incorrectly :(
Look at the image below!

You want to use the forward direction of the player and not it's rotation, when instantiating the fireball. (Remember: transform in your script is the player transform not the fireball transform.) Check https://docs.unity3d.com/ScriptReference/Quaternion.LookRotation.html. LookRotation will return the rotation based on player's forward and up vectors.
GameObject newSpell = Instantiate(Spell);
newSpell.transform.position = transform.position;
newSpell.transform.rotation = Quaternion.LookRotation(transform.forward, transform.up);
Not part of your question, but I would also suggest letting the fireball fly in the forward direction of itself not the player (as this leaves more room for later modifications)
rb.AddForce(newSpell.transform.forward * SpellSpeed);
