Smallest shells I have are 1/4 inch. I just got 8 very teeny tiny e's 4 of which should have no problems with the 1/4 inch shells, 4 however appear too small (hard to believe) for 1/4 inch shells (they are all very tiny). So my question is, is there a such thing as shells smaller than 1/4 inch??? If so, where to look for them? So would they make due with the 1/4 inch shells. These guys are soooo cute, and teeny I am just concern on finding, or making sure I have shells for them. Also, are these considered ants? or are they micro's? It is so hard to believe how active these little itty bitty guys are, There are pics of 7 of the 8 here in another thread, I took pics with a crabby cell camera (so not the greatest and they were on top of a perscription bottle under the lamp.) These guys 1/2 of them barely covered a single letter on the bottle (with their shell).
