In 7L water volume is definitely to make sure the move only so much food into the aquarium as the fish can eat in a short time, otherwise there is the danger that the aquarium water is bad and the fish die. I spend very little food, that is, a Paro can possibly eat 5-10 Daphnia, then he is tired. The water is living in the Paros not very healthy for Daphnia and they survive very long and not die, with other food animals similar, also hold the BBC not long by. Furthermore, I am of the opinion that Paros do not have to be fed every day, 3-4 times a week is sufficient. Only in young animals should be fed every day. With this amount of water 7L I would definitely change once a week 30% water.
