how long will frozen food stay good in the fridge?

[Runfrumu]

I'm thinking of just mixing alot of my fish foods together (spiralina, brine, mysis, cyclops) together in proportions to what I normally feed into one larger glad container and keeping it in the fridge to save some time on the preparing part. The main reason is so that I don't have to feed my fish flakes as often when I'm short on time.

After doing this, how long would it stay good in the fridge as opposed to the freezer, or should I just freeze it again and break off peices as needed?

Keep in the freezer, but not on the door panels, if you have a "auto defrosed freezer" door panels get heated to defrost, same with butter and ice cream, put them deep in the freezer section.
