When you are confident in the cycle's completion, I would reccommend stocking multiple types of smaller fish (five inches or under); that offers more visual variety than a few big ones. You might want to start with a school of about three blue/green reef chromis. They're attractive, hardy, and peaceful toward other tank inhabitants. A couple of other good choices for future stocking are the royal gramma and false percula clownfish. Just study any fish you're interested in and make note of their keeping requirements, size, and temperment. You'll find that your choices are wide-open.
