Guppies are killifish. They originally came from Africa where they live in puddles and ponds and eat mosquito larvae - like those of the malaria-carrying tsetse fly!
They are (for the most part) quite a small tropical fish and so a small sized gravel is best. They are live-bearers too. Fry (baby fish) will get trapped and die among even medium-sized gravel. Sharp sand (not river or beach sand that is rounded and compacts) in a natural colour is best. Wherever you get it, even a pet store, it will need to be thoroughly washed. And as the other gentleman said (above) boiling water is a very good idea. Having bigger rocks interspersed is perfectly OK, as is driftwood (again, remember the boiling water). And always have real plants (the pet store variety is best because it is usually free of pests). There is no substitute for them in ensuring the health and best colour of such fine little fish.
Good luck!

I have never heard to use peroxide, only white vinegar. I have gravel, river rocks, quarts and emerald rough in my tanks. Just make sure any rocks you put in there past the vinegar test, that you boil them if you got them from outside and that they aren't too sharp or rough so they don't cut the fish.

Most rocks that you find outside are safe to use as long as they do not have veins, are not painted, have been intensely boiled and do not bubble when dipped into peroxide.
BTW Guppies are not killifish and are naturally found within the New World...not Africa.

You can put in any type that you would like... but I would buy them from a pet store. Its not a good idea to put in rocks from your own yard or local river.... too many germs for your little guppies.
I wanted a more natural look in my tank so I got slightly larger pebbles, yellow and brown colored and put in lots of fake plants to green it up. I like it alot.
