I would stick with a pair of clowns. Maybe in a week or so you can pick up your cuc, like snails, hermits and shrimp. In another week or 2 you can add another fish or two.
It's important not to add too many at once, you dont want to overwork your current bacteria, you want it to adjust to the 2 fish then cuc then more fish.
You've waited this long, might as well take it slow. Better results that way. I promise.
