Food Expiration

I heard somewhere that containers opened more than 6 months ago should be thrown out because the food has no nutritional value. True or false? Thanks.

True. The vitamins are destroyed by prolonged exposure to light and air. I usually throw the foods that are beyond two months. Buy foods only that you can consume within 2-3 months.

Human food or dried fish food??

Human food or dried fish food??

Commercial fish foods here to be more specific.

I haven't seen any evidence of dried foods losing nutritional value like that.

i wouldnt buy a pound of flakes for a 10 gallon full of neons, but there shouldnt be much loss of nutritional value in 6 months.

I have read that you should freeze any food you can't use quickly. What I do is remove a small amount of food to keep as my daily use stock and freeze the original container. We've got one of those food saver things that vacuum seals stuff. I put the container in that, tightly closed with the original lid, then put it in a plastic bag and vacuum seal, then place in the freezer.

I only have two ten gallon tanks so any container of fish food is way too large for me to use up within years!

Probably not necessary if your talking about pellet, flakes, sinking wafers, or freeze dried foods but I don't see any harm in storing these in the freezer.
