I'll third the comment that you're already maxed out on bio-load. While the 1" of adult fish per 5 gallons is only a rough rule of thumb, (obviously, 1-6" fish is much more bio-load than 6-1" fish) it's pretty accurate over the entire aquarium spectrum.
Sadly, this is the big problem with nano-tanks...you really can't have much for fish in them. It's what keeps me from setting one up. I'd rather have NO operating tanks than to have to settle for one I wouldn't enjoy. (the hobby was always more about the fish than the living decorations (corals) to me.)
Since you already have one, I'd highly recommend making it a coral tank with maybe 1 small fish or 2 at the most. Maybe get rid of the clowns and get a nice pistol shrimp to pair with the goby.
