late to the party but I found good shells at Micheals/Hobby Lobby and even Home Goods when I was looking. Not sure on the species of shell they are, but they were large enough and I couldn't argue the prices. I think it was something like a 6-8 for 2 bucks. The bag from Home Goods was maybe on the borderline small size with some larger ones, but the fry certainly don't mind the smaller ones.
Biggest issue I seem to come up with is the 6 adults I have in the 10 gal tank seem to take turns resculptiong the sand in thier individual claimed territories by spitting it out into the other pair's territories.
