Yeah, I agree with that. I think I lean more toward emersed growth of the latter. You'll find out soon enough which it is. Some people have said that they haven't had any trouble putting emersed H. balsamica in with fish, while others have. Caution would be wise and it would behoove you to soak the stems for a few days just in case.The second looks like it might be Hygrophila difformis or Hygrophila balsamica.
