Fish Food expiration

[AquaShark]

Does fish food expire? When I bought my tank off of craigslist it came with a bunch of food. Some not even unsealed yet. I couldnt find an expiration date on any of them though. Anyone have any insight on this?

I suppose it would depend on how airtight and opaque the container is. Nutrients are destroyed by air and light. Without knowing for sure, I would toss it out. I try to only buy what I can use within 3 months. Some people prefer to buy more and store a portion of it in the freezer to give it a longer shelf-life.

Fish food does expire. At least the brands I get have dates on them, usually a couple years out but I only use for a year before I toss out. Like the other poster said sit out what you need for a couple months then store the rest air tight in the freezer/fridge. This keeps nutrients packed in longer.
