So you have been keeping your betta for two year without filter, Then
I am assuming you change 25% to 50% of the water every week. Is that
right?

Ok, I will replace fish. But Can I still run the tank in the future
without mechanica filter?
=========================
I small filter, called palm filters or even a small inside box filter would
be better than no filter at all. I have kept a betta now for 2 years in a
2g unfiltered tank and he is fine. :-) If you use a small filter you can
keep other types of fish that don't grow very large. A few guppies or
tetras etc. But then you'll need a small heater (bettas like heat too)
unless your home is in the mid to high 70s year round. Mine is so no
heaters are used here.
