Collision doesn't work with prefabs

Hi all, I'm working on a fishing game and I instantiated multiply fish with this script:

//

using System.Collections; // using System.Collections.Generic; // using UnityEngine;//

public class FishGenerator : MonoBehaviour { // public GameObject FishPrefab; // private double i = 0; // private double j = 0; //

 void Update()
 {
     i = Time.realtimeSinceStartup;   // tiene traccia del tempo reale
     if ((i - j) > 3)              // dopo 3 secondi inzia ad istanziare il prefab
     {
         var FishTransform = Instantiate(FishPrefab);
         FishTransform.transform.position = new Vector3(12, Random.Range(-4, 4), -2);
         j = i;
        
     }

 }

} I want that every fish instantiated collides with a Hoop, but only the first fish do it. The others (Clone) pass you by as if it were not there. How can I solve it? Do you have any suggestions? In below the Hoop script section for collision:

void OnTriggerEnter(Collider otherCollider) { Debug.Log(otherCollider.gameObject.name); audioSource.Play(); if(otherCollider.gameObject || otherCollider.gameObject.name == "Fish(Clone)") { Destroy(otherCollider.gameObject);

     }
 }

Thank you,Hi I'm working on a fishing game, and I want to generate multiply fish on the scene. I did this script to instantiate prefabs:

public class FishGenerator : MonoBehaviour { public GameObject FishPrefab; private double i = 0; private double j = 0;

 void Update()
 {
     i = Time.realtimeSinceStartup;  
     if ((i - j) > 3)              
     {
         var FishTransform = Instantiate(FishPrefab);
         FishTransform.transform.position = new Vector3(12, Random.Range(-4, 4), -2);
         j = i;
        
     }

 }

}

But only the first fish collide with the hoops. The others (Clone) pass you by as if it were not there. How can I solve it? Do you have any suggestions? In below the Hoop script section refers to the collision method:

void OnTriggerEnter(Collider otherCollider) { Debug.Log(otherCollider.gameObject.name); audioSource.Play(); if(otherCollider.gameObject || otherCollider.gameObject.name == "Fish(Clone)") { Destroy(otherCollider.gameObject);

     }
 }
