PHP OO Basics final challenge 4/7.

Can anyone tell me why this doesn't pass? Seems straightforward: add the parameter, then set the property to the parameter.

"Add a fourth parameter, $species, to the Trout constructor. Set the species property to that parameter within the constructor."


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

    function __construct($name, $flavor, $record) {
        $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 {
  protected $species;
  public function __construct($name, $flavor, $record, $species) {

    parent::__construct($name, $flavor, $record);
    $this->species = $species;

Hi Dan,

The $species property should be public like the others, not protected.

Thank you!

You're welcome.
