Re-Stocking Dwarf Gouramis

[Zante]

I have a fluval roma 90 with upgraded lighting and filtration

I have at the moment
3 dwarf gouramis (1m 2f)
2 blue rams
4 adolfo corys
6 cardinal ttras
1 african armored shrimp
1 bristlenose (still small)

The rams, cardinals, corys and bristlenose are soon migrating to a new tank, so I wanted to re-stock this one.

I will get 6 kuhli loaches
and I'm undecided wether to get 10 harlequin raboras or another trio of dwarf gouramis

Opinions?

Maybe some other suggestion?

... I quite like pearl gouramis, but I'm afraid that a trio of them will create problems with my existing dwarfs.

... or any other asian biotope fish you can think of. I will evaluate any suggestion.
