2 blogs in one website

Hello, i am using wordpress on my website and recently i decided i also wanted to have spanish content without messing the english feed in the main page.

Decided to add a new WP install named “spanish” but i cant make spanish site get feed from the spanish site, keeps displaying the english feed even after i pointed the path

<?php
            // Include WordPress
            define('WP_USE_THEMES', false);
            require('./blog/wp-blog-header.php');
            query_posts('showposts=6');
            ?>

and

<?php
            // Include WordPress
            define('WP_USE_THEMES', false);
            require('./spanish/wp-blog-header.php');
            query_posts('showposts=6');
            ?>

what can i do so the second site displays the spanish feed not the english feed from the first blog?
