Stuck: Add a 4th parameter, $species, to Trout Constructor. Set the species property to that parameter w/in constructor

Unsure what I am doing wrong here and can't find any good examples to help me.

fish.php 
<?php

class Fish
{
    public $common_name;
    public $flavor;
    public $record_weight;

    function __construct($name, $flavor, $record,$species){
        $this->common_name = $name;
        $this->flavor = $flavor;
        $this->record_weight = $record;
    }

    public function getInfo() {
        $output  = "The {$this->common_name} is an awesome fish. ";
        $output .= "It is very {$this->flavor} when eaten. ";
        $output .= "Currently the world record {$this->common_name} weighed {$this->record_weight}.";
        return $output;
    }
}

class Trout extends Fish {
  function __construct($name,$flavor,$record,$species){
    $this->common_name = $name;
    $this->flavor = $flavor;
    $this->record_weight = $record;
      parent::__construct($name,$flavor,$record);
$this->species = $species;
  }
   protected $species;
}
?>

You dont need to assign existing parameters from the parent class as you are doing it in the parent::__construct

<?php
class Trout extends Fish {
  public $species; // Task Three

  function __construct($name, $flavor, $record, $species){ //Task Four: Add species
    parent::__construct($name,$flavor,$record); // Task Two
    $this->species = $species; // Task Four: Part Two
  }
}
?>

Leave rest of the code unchanged. I suggest you start the challenge again.
