I'd say you're full up. When you move to your larger thank and as all your inhabitants grow, you'll find you're pretty much maxed out.

Like you mentioned earlier a bigger/better skimmer/filtration system will help you keep everything in line from now until later.

I wouldn't add anything unless it was smaller fish, or fish that won't compete for space, food, or a home/hiding place. I'd be very wary of adding any smaller fish.
