Hey guys and gals. First post here so please be gentle. 
I have a 55 gallon tank (fairly new) that currently houses 6 tiger barbs and 4 green tiger barbs. All of them are still babies of between 1/2" and an inch. I plan on picking up a small school, maybe 8-10, of some form of tetra or danio to go with them. And also plan to get one of the smaller pleco species (that stay around 4-5" max). Now, my question is, what would be a good centerpiece fish or pair of fish? I really like the cichlids and had considered either some rams or a pair of Acei. I would like something a little bigger than the barbs but not so big / agressive that it would kill the barbs or the tetra.
Any suggestions? The tiger barbs are already there but the tetra can be swapped for something else if you have a good stocking suggestion.
details on the tank:
roughly 48" x 13" x 19"
few plants (plastic) on each end of the tank
2 pieces of driftwood kind of off to each side (one on left, one on right)
can / will add some stones if needed for the fish
standard aquarium gravel (2 25lb bags of black gravel, 1 10 lb bag of white). top of the gravel looks kind of like cookies and creame
Pengiun 350 HOB filter (I believe that's the one, for like a 75 gal tank?)
regular old heater (think 250 watts? again, whatever wattage it is is adaquate for the tank as I overbought on the filter and heater).
