Do you think egg crate will make conveniant sized food cubes for the fish? I was thiking of just putting some plastic wrap under the egg crate, pouring the food in, and then popping the cubes out and putting them in sandwich bags. I can easily cut blocks off from the huge slab of frozen food, like I do now, but it will be easier with cubes LOL! So will it work? I don't have egg crate at the moment, so I don't know how the squares are.
