Shell suggestions for Es

[Kaleighshermies]

I want to get some D shaped shells for my E's around an inch to a inch and a half in size. Can anyone recommend what type of shell(s) to get. Mostly interested in Neritidae but have read they may not use them with the spiral in them. Would still get them just in case and I know the PPs may like them too. Also need suggestions of where to order online. Naples.com doesn't have the sizes I need.

Other kinds of nerites work, Starry nerites were a hit with mine but are hard to find.

Moon shells are popular. The lighter ones, shark and whale eye are used interchangeably depending on the source.

Tonna and ton sometimes. Many times they are too thin to be safe.

Bai and japonica zeylanda (sp?).

Japanese Fairy shells sometimes.

Thank you. I will have to do my research and check them out. Appreciate it!
