I recently got 4 guppies. I am not sure if they will breed or which are female or male or if they are just different breeds. I have 2 orange guppies and two grey guppies with small blue tails. I am so confused! I just want to breed them! It didn't say on the tags outside the tanks if they were male or female or a mix. It just said fancy guppies 3.99.

Male guppies are much more fancy then female guppies. They have the brightly colored fan tails, and have much smaller bodies then the female guppies.

If you have males and females, don't worry, they will breed on their own and before you know it you will have baby guppies in your tank.
