Should I store bonito flakes in the fridge?

I'm curious, what's the best way to keep bonito flakes fresh? Is it recommended to store them in the fridge, or is there another method that works better? I've heard mixed opinions and would love to get a definitive answer from someone who knows the ins and outs of food storage. Help me out here - should I be putting my bonito flakes in the fridge, or is there a better alternative?
