Right now, I am in a predicament. It is getting really cold where I live, and my mom's fish is being affected. The poor female (Belle), is currently in a one gallon tank with no heater and an under gravel filter. I really wish I could put her in my heated 10g with no fish currently, even for just the winter, but my parents would disagree. I am not allowed to even change the water because my parents like to rub it in my face that their fish with the 1g tank, no heater, and NO WATER CHANGES, has survived without sickness and that all of my fish die. So I need your help fish forumers, what would be a good heater for a 1g tank? I will try to negotiate something tonight with my parents, but I don't know how good it will go.
Is this heater any good? http://www.petsmart.com/product/inde...ductId=4455060
Is there any cheap heaters for an 18g too?
