These are aquatic plants. Anyone knows the name please? Well. For a week more and most of them stems rotted. So, wondering if its planted by submerged in the soil or what.
Take these with a grain of salt, as it is quite difficult to tell from a single, far-away, picture, and I am no expert on aquaria or aquarium plants.
The narrow-leaved (lanceolate) one appears to be Pogostemon, possibly the species * stellatus*, though I think this should (under optimal conditions) have red stems and upper leaves. This seems to have strict requirements for growth of added CO2 and intense light.
I found a site Tropica.com (I have no affiliation with, nor is this an endorsement of, the company) that sells a lot of aquarium plants and has good listings of the conditions needed for growth, along with pictures and descriptions, so it might be worth a browse through there to see if something fits better.
The second, broad-leaved with toothed margins, plant might be Erythranthe guttata (Monkey Musk), which is a common (sometimes invasive) plant of stream margins, but I don't know how well it will grow fully submerged. It will certainly tolerate short submergings (a few days), but as an aquarium plant??
