Can someone help me identify these two plants for me?

My guess

Cryptocoryne usteriana
Hornwort

Cryptocoryne Undulatus ‘Red’ Broadleaf​

Hygrophila pinatifida for that first one. I almost thought crypt too but it's got a stem not a rosette. It's grown emersed so the leaf shape is weird and it's dark, which is causing the confusion.

Circled here you can see where leaves are growing from the stem of this plant, which completely rules out cryptocoryne.

2nd for sure is hornwort.

The pet stores here grow every plant emersed and im keeping them in this tank until i finished my new tank.
Does growing plants emersed bad for the plants?

Most aquatic plants have both an emersed form and a submersed form. Many grow emergent either seasonally or even all year in some cases naturally in the wild. They do change back and forth between the two in those respective conditions. (Hornwort is not a plant with an emersed form, it's 100% aquatic, but the hygrophila is one that has both forms)

Plant suppliers often grow them emersed because they grow a lot faster when exposed to the natural CO2 in the air, where they'd have to pay to supply it if grown submerged. They can sell more of them faster and with less money out of their pocket to get them growing fastest.

It just means it will take some time and luck to readjust to living under water now in your tank. Most of the time plants will make the change fine and melt off old emersed leaves, but sometimes they don't take the move well and will totally melt off. I would suggest letting it adjust and don't move it until it has been well established now.



Some plants if left reaching the surface may start growing out of the water and growing emersed again. Rotala, ludwigia, limnophila, hygrophila, bacopa, and hydrocolotyle are good examples of plants that will easily grow out of water when given the chance. There are many others, but these are some examples of stem plants that do it.
