I hope we didn't steer you away from GBR they are beautiful fish but you still have to match their personalities in a community tank.
Here are 2 of 3 of mine in my 120g they are 1 balloon (F), 1 Long fin (M) and 1 Regular Fin (M)
There are Angels, Rummy Nose, Cardinals, Sterbi, Dwarf Pencils, Otos, Congos granted it's a big tank heavily stocked and planted but the Reg Fin GBR nose his limits. If it were a smaller tank I would just leave the Pair.
I keep my breeding Long fin pair in a 20gal tall with easy growers so she can hide when the honeymoon is over until she is ready again.
I also have 10+ Long GBR raised from fry in a 33L with 30 tiny Cardinals and a few Otos heavily filtered.
