Help With Choice Of Centre Piece Fish

[Dutsey]

I currently have the following stock in my 125l

5x Black Ruby Barbs
10 x Tiger Barbs (5 Green and 5 Normal)

I am after a Centre Piece fish and bottom dwellers (pref not corys as trying to keep to Asia Biotape - does anybody have any suggestions?

For the center piece, I would add a black paradise fish. For the bottom some kuhli loaches 6-8 of them.
