Will female guppies be better off without male guppies?

Thanks, will move fish into new tank as soon as it arrives and I'll do as you suggest and take most of the old tank water with them. The new tank does have a filter, not sure what type but planning to add some of the old filter medium to it if possible, or do you think it's not cycled enough to bother?

When I have been doing the daily partial water changes I have used water that has been left to stand for 24 hours to get it too room temperature as well as adding the tap save stuff and now adding just before use the water conditioner.

Thanks to your help my 6 guppies are still alive and looking a lot happier, their top fins up and tails fully open, which they haven't been. Not that active as the temperature is too cold, but a lot more then they were!
