Does "Green Flake" fish food go bad?

Question

I bought a pretty large bag of "Green Flake" fish food which is supposedly top of the line. I have had it since November 06. My question does this type of food ever go bad and if so when? I don't want to be feeding my fish bad food.

Answer 1

It can get stale and loss it's vitamin content. If yours has been fairly well sealed up since you got it it should be ok to use. Try dividing it up into several smaller zip to bags and placing it in the freezer to help preserve it long term.

If its all green, It will not be poisonous or anything like bad meat is to humans if its ancient. It will just lack some vitamins & stuff that are good for fish. Not the best thing to feed them, but not fatal if you give it to them on occasion.

Green fish food is so cheap (since its mostly seaweed & algae), its worth it to just buy a fresh supply & not buy in bulk.

I like the Ocean Nutrition Formula Two flakes for veggie flakes. They're cheap and very high quality.

Answer 3

All foods, nomatter what brand they are, go bad. They go bad after about 3 months or so. Try buying as much food you need based on how much you feed per day and apply that to the size of the pack the food comes in and buy only as much as you need.

Answer 4

Yes it does, over time nutrients are lost. How long depends on how you store it. The food should be kept dry, cool, dark, and as air tight as possible. Depending on how you store it, it might last a few weeks or as long as a year, but you won't be able to tell visually how bad it's gotten and it's safer to buy new food if you aren't sure.
