Dear Sir, Icame To Know That We Need To Take

Dear Sir,
Icame to know that we need to take omega-3 and omega-6 fatty acids in a balanced way. But when i was looking at the fish oil capsule bottles the label is indicating only omega-3 fatty acids and not omega-6 fatty acids. how i will come to know how much amount of both the components are present in fish oil from its label. Please help me out
Thank you
