I bought a 100 or more and some other stuff and got a killer deal but I am not 100% sure what they are. If some one could help out with the scientific name and such what they eat and so on.. Thanks

Those appear to be Ricordea yuma. Tolerant of a wide range of conditions, though they dont seem to like really intense light. Feeding isnt totally necessary, but they will eat most any small, meaty, zooplankton-like food (which will fuel faster growth/splitting). Hardy once acclimated to a tank
