Frozen food kept in the refrigerator (how long?!?)

[helicopter]

I have frozen brine shrimp and blood worms cubes in my freezer. I take it out, break off small pieces and put the rest back in the freezer. I take the frozen pieces and thaw them in a cup of warm water and then strain in a brine shrimp net. Then I put the very concentrated liquid of food into an eye dropper bottle along with the equivalent of probably 1 gallon of waters worth of a Jungle Antiparasitic tab. I feed from this and keep this bottle in the refrigerator. How long do you think I can keep this bottle before the food spoils in the refrigerator??

It should be good for at least a couple of days so long as you refrigerate it. I would toss it and make up a fresh batch after 4-5 days.

What kind of fish are you medicating? Are they eating the medicated food for you?

Fish

I am trying to medicate a dwarf puffer which is currently housed (peacefully for now) with two pristella tetras and a pygmy catfish. I also have half of a jungle parasite tab in the tank. The tank is a 6 gallon eclipse. I know, thats a small tank for that many fish but I have been checking the water parameters constantly, doing %50 changes and there are a lot of plants in the tank. As they start growing I may have to seperate them. Also I know the tetras should be in 6 or more, I did have more in the tank but they died so I decided to get a puffer.
