It will keep the fish from being freezer burned and let it keep longer. You can do this with chicken also. It depends on how long you intend to freeze it. Fish frozen in ice will last longer due to air next to the meat can cause freezer burns. If you intend on using it in less than a year or so, you can freeze it on a piece of wax paper and when frozen, transplant into a large ziplock bag. This allows you to remove the amount you want, and not have to dethaw the whole amount. This way, you can remove individual portions at ease.
no. they can even live in freezing temperatures. they're meant to be pond fish, and will grow very large.
Salt water fish need salt water, fresh water fish need fresh water. Humans need air. Its just the environment that it grows in.
fish do need water they have gills which extracts (to take) the air from the water
Fish need clean oxygenated water and food.
Fish need water to live if fish doesn't have water they will die.
Depends on the fish.
because fish need it to breathe. just like humans need air to breate. to fish, water is air.

of course you do you need the fish to have WATER because every fish in the world needs water so the betta fish needs it to,to live so the betta fish does need a FILTER
No. I disagree. I clean my fish before freezing. There can still be microbial activity in frozen food. That is all the more likely in a fish that is still full of fecal matter.
Saltwater fish require salt water, and fresh water fish need fresh water, you can't mix them, or the fish will die. You need to look at each individual fishes needs as to what temp they need their water to be. There are some saltwater fish that can survive in fresh water, but it is not healthy for them.
Fish are cold blooded, therefore their body temperature is virtually the same as that of the surrounding water they live in. Each fish species has an optimal temperature that they prefer. Some fish live near the poles and can survive in water near freezing, other fish live near the equator and need water as warm as 30 deg C (85 deg F).
