If you don't get a filter you would have to do 100% water changes to really clean the gravel so ammonia doesn't build up, and that would be pretty hard with a 10 gallon.
And a betta sitting in one cup of water for a month is just barely surviving. I would not use that as an example because that betta is obviously going to have a short and horrible quality life.
Oh, I forgot to add that without some water flow your tank will have temperature extremes because the water around the heater will heat up and it will turn off leaving the rest of the tank icy cold. Believe me, I once had a filter malfunction in my 10 gallon tank and the water on the top of the tank as well as around the heater was warm, but when I stuck my hand in to fix things the bottom of the tank was frigid! I also have a betta that loves to play in the flow, so some water flow is good just not a high flow because bettas really aren't the best swimmers.
Alright, I was just wondering because at the stores you will never see filters. I'll buy one, thanks.
