Regardless, i can't say enough about how it's better to take it as slow as possible. Creating a complete and balanced fully contained ecosystem can be tricky. If you're just doing fish and no corals you have a lot less to worry about. Do not add all the fish at once no matter what. I wouldn't do more than one or two at a time with a tank that small. And space adding them out to once a month or more.
