Yep, all petstores should sell some sort or another of the gravel
before you buy the pellets, make sure it has a fish or shrimp meal as the first ingredient. Bettas are carnivores, and thus they need to eat like one. :) Most petstores have a freezer in the back where they might keep something like frozen bloodworms. You could feed a tiny little bit to your betta as a treat occasionally, most bettas love them.
Anything that they are selling in the fish section should be fine for your fish. If you just so happen to have a pair of pantyhose at your house, run it over the ornament to see if it'll rip. If the pantyhose rips, it isn't safe for your fish. If it's safe, rinse it well in hot water before putting it in.
(most shoe stores offer those free little pantyhose sock things for women to wear when trying on shoes. If you don't have pantyhose in your house, those things work well )
