Please help identify some random growth in the tank

[Ana Gropper]

Hey everyone,

We recently had a big tank aquascape change... we are getting things together to post the build thread soon but in the meantime... I found a few new little growths (I saw them before but too small to identify). Could anyone help me identify these so I can place them appropriately.

They are both shown open and closed.

Thank for your help

I love them both
