Like others have said, a bowl just isn't the place for a fishy, crazy as that may sound to you now. Stick around here long enough and it won't! So, either run away fast or stick around and get a new family.
So, here are some links to help, if you are interested in keeping with the hobby:
Get yourself a nice little tank.
This 6.2g from PetCo gets rave reviews around here (and it is even on sale through today!). That kit comes with all kinds of stuff. In addition to that, if you want to keep tropical fish (Guppies included), you'll need a little heater.
This one from Drs. Foster and Smith would do well in that tank (the 25w will be fine in that tank).
So, for $65 you have the whole setup bascially. All you'll need are the fish, their food, and some water conditioner.
BAM!
