First, you may want to consider why the LFS sold you 2 Tiger Barbs without warning you of the difficulty you were about to encounter.
Next, you almost need to srat over with your fish selection. You have no room in a 10 gallon aquarium to mix this many species of schooling fish with any long term success. I would remove the Tiger Barbs, Serpaes, and Silver Tips. All of these fish are "nippy" community species and do best in much larger aquariums, say 55 gallons or more.
You can add 4 or 5 more Glowlights and a few more peaceful species, such as Lemon Tetras.
