I have 3 tiger barbs in my 10 gallon tank, I am wondering if there is any way of distinguishing male from female, if so, how? can you please help me?
You are asking how to Sex fish. This is difficult in many cases but for Tiger Barbs it is a little easier. Males tend to be more colorful overall with a brighter red in the dorsal fins as well. Females tend to be wider and generally larger then the male with less vibrant coloration.
