ok so awhile back i purchased a few cherry shrimp and in with the bag was what i thought was a guppy fry but in growing i noticed it is what i believe a female killie i dont know what kind but i the store the store that i purchased the shrimp from they were also selling mated pairs of killies that were in the same tank. now i dont know if i should keep it, get a few more or what i should do

I think Killi's prefer to have several of their own with them. Killi's are kind of unique in a couple of ways, and I'm no expert, so you should google "Killifish profile" or "Killifish care" and you should get several good hits.
