Spawning for a "for" loop threads in a forever block

Requirement : I want the threads to spawn in a forever block , and the number of threads is parametererised.
Problem facing : The below code is only executing for the i=0 ; Can you please help me whats the bug in the code , and how it should be changed to meet my requirement

module fork_join_none;
  
  initial begin
    $display("-----------------------------------------------------------------");
    
    for (int i = 0;i < 5;i++) begin
      automatic int j = i;
      $display("----------------------------------i=%0d----------------",i);
        fork: label_1
//        automatic int  j=i;
          begin
            test1(j);
          end  
        join_none
    end
     
  end

  task test1(int j);
       forever begin
         #5;
         $display("!!PORT %d!!! delay task started %t ",j,$time);
     	 #5;
         $display("!!PORT %d!!! after delay %t ",j,$time);           
       end
  endtask
    
    
initial begin
#1000;
$finish();
end
  
  
endmodule

use automatic keyword in task declaration otherwise here as you can see int j will have static storage , so last thread will overwrite previous j values.
