Will the baby fish live in bowl without a filter if yes for how long?

guppy fry can live in a bowl without a filter, but you will need to net them up and completely clean out the bowl every second day. they also will need a heater, not negotiable! keep the water at 26-27*c (78-80*f) and prevent temperature fluctuations. they can survive in there for one month maximum before they get too big. this is just one example. you will need to specify what type of fish it is to get an accurate answer.
