There not really eating them they are trying to get the oxygen out of them so that they can survive if they are doing this unless they are a betta fish it probably means there isnt enough oxygen in the tank for them which usually happens if you have a fish in a tank to small for it or have to many fish in one tank you probably want to upgrade your tank or get rid of some fish if they are doing this. Also if you dont have a filter for the tank get one! it will help add oxygen to the water and is necessary for almost any fish to survive.
