Array of game objects

I am trying to make a 5x4 grid based game with jellyfish gameobjects rock gameobject and blank spaces.

I need help finding a way to attach these objects to a 2d array so that I can later move them in the grid.
Each level in the game is going to start with the jellyfish and rocks in different spaces so if possible I need an array that can get the gameobjects based on position.
I am using c# for my code.

Not sure what the question here really is. Typically you’d want all of the objects in the grid to have a script that can store their grid coordinates and type

public enum ItemType {
    Rock,
    Jelly,
    Blank
}

public class RockJellyOrBlank : MonoBehaviour {
    public ItemType Type;
    public int X;
    public int Y;

    public void SetCoords(int x, int y) {
        X = x;
        Y = y;
        transform.position = new Vector3(X, Y, 0); // some multiplier here to get wanted spacing
    }
}

Then have a class with an array that holds these objects and the methods for finding and moving objects around in the grid.

public RockJellyOrBlank[] Items;
public int Rows;
public int Columns;
void Start(){
    Items = new RockJellyOrBlank[Rows * Columns];
}

public RockJellyOrBlank GetItemAtCoordinates(int x, int y){
    return Items[x + y * Columns];
}

When an object is clicked for example, you can then get the RockJellyOrBlank script from the clicked object and then calculate theindex it is in based on its X and Y and move it to anothe grid cell for example

very simple just make your jelly fish have a tag and it doesnt matter if it instansiated on runtime

this will return all the objects that are on the scene and have a tag of “myJellyFish”

and then to access position

       GameObject[] myJellies = GameObject.FindGameObjectsWithTag("myJellyFish");
         if (myJellies.length > 0)
                     print(myJellies[0].transform.position);
