Guppies

I haven't kept fish for about 4-5 months now and fancy getting back in to
the hobby.
I have a 4.5ft x 2.5ft Tank but only want to start back into the hobby with
Guppies.. I want females and males so obviously there will be fry but can
anyone tell me what kind of bad things I should look out for?

Thanks very much ;-)



Just because I don't go to bed with ugly girls on a Friday night doesn't
necessarily mean that I don't wake up with some!!
