you would have to have some water movement and do small daily water changes. i had a ten gallon once for guppies with just an air pump no filter, for feeders
Depends on the tank size actually, guppies will not dirty the water like other big fish. You can keep guppies with out filtration. You will need an air pump. you will also have to do regular partial water changes.
Operate an airpump and a sponge filter. Simple setup and sponge filters can be DIY or bought from stores. It's your choice. Just as a note, be careful when feeding them to your fish as some feeders tend to carry pathogens which can be detrimental to your fish's health.
