Growing up my Dad kept a tank and stocked it with whatever he wanted. There were angels and barbs in together. My Dads fish keeping skills sucked(sorry Dad). The angels get large and terratorial. Once the angels are mature I doubt the barbs will mess with them. That size tank is good to allow the angels to have a territory and the barbs still have room to with out having to mix much. The issue will be getting the angels big enough to survive the barbs, because once the angels are mature they will harrass any new fish you put in. The only other option is to let the angels mature then redecorate the tank and really move some things around to screw up their sense of territory then add the barbs. Depending on the size of the angels you buy this could take a year or less before you could ad barbs.
Look at Dr Fosters & Smith for ordering fish online. My friend just got an order in from them.
