I actually think the first one looks like Micranthemum umbrosum.Pretty sure the first one is Hemianthus micranthemoides.
Second one I have no clue, but Echinodorus species are not native to North America and I'm sure that's not one.
I'm pretty sure you don't have Hemianthus Callitrichoides. As far as I know it's not found in the wild in Alabama like Micranthemum umbrosum is. Look at the link I provided. Micranthemum umbrosum is also called baby tears and to me it looks like the plant you have pictured.after comparing on line, I'm convinced that the first one is Hemianthus Callitrichoides as for the second, I suppose he would be easy enough to put in the tank, if the tank wasn't already filled with otheres, as is, and not knowing who he is (so I don't know if I can feed him to my turtle), I guess I'll give him a toss
thanks anyways guys
