Yes, any type of Barb will go together, I have a 38 gallon with about 7 different types of barbs and only thing they do is school together or chase. It seems to work perfect.
The Tiger Barb is a schooling fish, and needs at least five to seven other Tiger Barbs to be comfortable with, and to behave normally. They are usually fish that will develop a pecking order, and need plenty in their own school to do so.
