How often should I buy new fish food?

Ssnaaiil

I have some pellets, flakes and freeze dried daphnia, they have been open for 1-2 years…should I buy new foods? Do they lose nutritional value after being open for so long?

After 1-2 years, yes, you should buy some new food, at least for the flakes and pellets, I am not sure on freeze dried daphnia. The food will oxidize over time once opened, becoming stale and losing nutritional value. I don't think there is a scientific answer to this... yet... some will say a 1 year limit, others 6, and others buy enough food for only 2-3 months. Personally I buy enough flakes for about 2 months at a time max, pellets I usually let go a little longer, closer to 6 months. I would toss food if it was over a year old even if it doesn't smell stale.

I think I really you want to use it within a year. But I think it’s really more of the issue of it getting stale. I have a small food container that I keep a month or two worth of food in. I place the rest in the freezer and top off as needed. This will make the food last much longer by avoiding it going stale.

How much longer? Not totally sure. But it is the best way to have something last longer

You guys have potato chips don’t you? Perhaps you call them crisps? If you open a packet of any of that kind of man made processed food how does it taste after a month from being open?

I toss six month old dry fish food in the bin.

Thanks everyone for your input. I am going to be buying new fish foods! I want to make sure my fishy friends are well taken care of.

At the very least, at least pay attention to the expiration date!

Most fish foods have an expiration date on them somewhere, follow that for guidance. (Assuming the container is sealed when not in use, and is kept dry, etc)
