Adding Kribs To A Community

[CallMeJoe]

I have a lightly planted 55 (US) gallon tank and currently have:
2 medium clown loaches
6 otocinclus
6 serpae tetras
2 opaline gouramis

I would like to add a central focus fish, and am considering Kribensis. I have no interest in breeding (no place to keep more fish and no interest in selling them). Should I add 2 males? Will they be OK in this size tank? If not, do you have any other suggestions?
FWIW, I also am considering adding several more serpaes to my school.

They should be fine in that tank. Males are less aggressive then females.

Shouldnt be a problem with them.A single krib will also be quite happy on its own.When my male krib died I kept the female on her own and she shared the bottom of the tank with a Bolivian ram
