New Centerpiece Fish

[Linway]

Hey all,
My 100L tank currently contains:
 
4 platys
10 neon tetras
4 bronze corydoras
1 bristlenose pleco
2 assassin snails (were introduced simply to take care of a pest snail problem I had)
1 betta
 
Basically as the tetras have grown they have started to nip on the bettas tail so I've decided to buy a small tank to put him in. However I would like to replace him in the main tank with a new "centerpiece" fish, but I'm not sure what to get, I only know I dislike gouramis (there may be one of two sub species that would appeal, I just haven't found them).
 
So what do you guys suggest?

maybe a Ram or other dwarf cichlid

I'd suggest an apistogramma sp. Agassizii, cacatuoides and hongsloi are all very colourful (males at least)

Perhaps one or two dwarf gouramis!

This! I love the neon blue gouramis.
