i would like to know how long frozen bloodworms stay fresh in the freezer?

I think for a pretty long time. I would think you would use them up before they go bad. I am not expert but I bet at least 6 months or maybe longer.

Yeah, I would think frozen fish foods keep for a long time. Check the packaging carefully as there will probably be some advice on there as to how long they can be stored before using

thank you for the fast reply! =] i have fed frozen bloodworms that were my old tropical fish food and my goldfish loved them!

I find that with the frozen bloodworms, that they last longer and do not get any signs of freezer burn if I keep them in a zip lock bag. And have them in an area of your freezer away from the door so they do not get temp changes with the door being opened and closed.
