** Do guppies need a specific temperature, or can they live in cold water all right?

** Can I keep all female or all male guppies to prevent breeding? Or is it better for them to be mixed up, for whatever reason?

Thanks!

Guppies can survive in cold water, but you should find they'd healthier and would live longer if the water is slightly heated (around 76-78F). This could just mean putting the tank in a warm room, or adding a small heater.

Guppies do just fine with only one gender in the tank. You may find, however, that females you buy could already be pregnant. I'd go with an all-male tank, as they are usually brighter and prettier than females, and you have no chance of having any fry

Good luck with them, and welcome to the forums!!
