So I got a 10 gallon for him instead, but I don't have a filter for it. How am I going to cycle it and how long will it take?? I have him in a 2 gallon bowl for now and I'm going to change the water twice a week, just like my other tanks. So how am I going to cycle a tank without a filter?? I have a heater for it and decorations, I just ran out of money for the filter. Oops, silly me.
