I have a female betta in a 10g with water filled up to 6 inches, and there is a heater and an ornament. The tank is getting the smell of rotten eggs...one I am all too familiar with. I think it's because waste has accumulated on the bottom, so should I dump out all the water and fill the tank with new water?
I would like to breed and raise bettas sometime soon...next long weekend I guess, when I have time.
