Two of my friends have a betta fish in a fish bowl without a filter.I can't have a filter because of many reasons,and the only pet I can have now is a fish.My friends say that their bettas are perfectly happy without a filter,one is living now for a few years.
I can clean the fish bowl(yeah,I will keep my bettas in a fish bowl-it will not be too small for the bettas,I will make sure of it)even 3 times a week,it is no problem.
Also,one of my friends filter the water for their bettas in a kettle(I have a new Brita one)and leave the water to cool down and use it for the fish,and the other one leaves the tap-water for one day(without the fish,in another container)for the chlorine(and all the "bad" things in tapwater)to evaporate-how should I do it and can I keep a betta fish without a filter in a medium-sized fish bowl?
EDIT: I will have only ONE male betta in the fish bowl.Should I leave the water to evaporate or to the kettle thing?
