Those temps are certainly possible for my basement and I doubt I'd need a heater but I would probably have one just as backup.
 
I'm seeing pictures of some beautiful comets. They seem quite nice. Flaringshutter, you said that fancies seem to be more net and hand friendly. Would you say that they have more personality? Or are more interactive with people? If I am going to make the committment to a fish for the lifespan that a goldfish has, I want it to be a personalble relationship. My kids will also get attached to them I think.
 
When you say that a large sump will allow me to keep more fish, can you define large? I have only seen a sump set up once and I am really clueless about how to do it. I'll research it though, don't worry!
