What are the advantages of freeze dried fish food over fresh food?

There are 4 basic guidelines to selecting the right food for your fish - what type of diet your fish eat (herbivore, omnivores, etc), where & when to feed your fish (some are bottom feeders, while others eat from the top of the water), variety and freshness.

Piranhas are omnivorous, so they will need a well-balanced diet. I recommend buying frozen foods or freeze dried foods from your local pet store. To add variety to the proteins you will be feeding them, you can also feed your piranha some fresh vegetables such as some raw potato/spinach.

Take a look at the Aquarium guys website. They have a good range of freeze dried foods for fish, including blood worms and shrimp flake etc. http://www.aquariumguys.com/dried-food.html

The website That Pet Place, has a good selection of freeze dried fish food. http://www.thatpetplace.com/aquarium-supplies/freeze-dried-fish-food#!freeze-dried-fish-food

Freeze dried coffee has few advantages over regular coffee. It is very portable and comes in single packets that can be easily taken to work or any other place. Moreover, it is faster to make and only requires a cup and hot water (no coffee maker like with regular coffee). Final advantage is that it is pretty easy to get the right strength of the freeze dried coffee. Only thing drinkers have to do is add more crystals/water.

Yes there is, in freeze-drying process they use a cold temperature and in dehydrated food they use warm temperature. In the freeze-frying process the fresh foods are frozen first then the moisture removed in a vacuum chamber and since the food remains frozen during the process, the food's cell structure don't change.

You should buy approximately enough food to feed you fish for 3 to 4 months. It will guarantee the right vitamins are given to you fish as written on the label and will keep the food in a fresh state.

Yes. All freeze-dried food has an expiration date;however it lasts much longer than fresh food.
