I so want a betta now!!!!!Do they need a filter???? Because i really want to get a betta or several! I have means of heating the tank.. Because i can but a cheap tank, with some black grqvel adn a few live plants... And how would i go about dividing the tank??
No, but if you want a tank big enough to divide (5 gallons or larger) it will make your life easier to have a filter. And to divide the tank, you just need to purchase a divider, or make one yourself. They are just mesh things you put in the tank to separate the bettas.
Im hopefully going to get a cheap glass tank. Then make my own divider.. I am going to eventually get a filter but they will be without for a month or so..... it will hopefully be a 10g but if not i may just get a single betta in a 5g?? Or i may divide it.
