Temperament Of Opaline Gourami

[Dan-CR4]

How would these fish be with rummy nose tetra and blue emperor tetra. I also got 2 keyholes and 2 bolivian rams and all live a peacful life except when the 2 bolivians wanna square up to each other every now and then. Just wondered if I was to put 2 opaline gourami in with them would they get on ok with inmates I already got

thanks for any advice.
