[lohpaul9]

Hey guys could you help me identify these plants which I bought at the LFS on impulse?
I think the top one is Amazon sword but i dont know about the rest
Could someone provide information on how to keep them as well?

The first two are sword plants ... but can't tell what species ... might not be Amazon

The other two are hornwort and Bacopa caroliniana (I guess)
