is it me? but when i see pics of betta tanks on here some dont seem to have any heaters or filters, surely they need some filter and some kind of heater?
It really depends on climate. I live in So. Cali and never turn on the house heating or airconditioning. The temp. in my Betta tank fluctuates so I have a heater for them.
If you have a central heating/cooling system in your home, you don't really need a heater for a small tank.
i dont use heaters when it is warm. (i live in alabama)
when it gets coler, i just heat the room they are in to about 85 or use a space heater.
i think i might actually be a betta myself. i have to put on heavy clothing when it gets below 80...
Personally i think that bettas like all fish, should be kept in heated and filtered tanks. Most filters have the option to slow down the current. I do not see why people put bettas in 'containers', if you can't have a tank with filters and heaters ect. for the fish, why buy one in the first place?
