It's not this. The plant is Alternanthera sessilis; it's not truly aquatic and can't be grown in the tank long term.

The second pic is Alternanthera ficoidea and the third pic is Hemigraphis repanda. Both of which are non-aquatic....

I am curious as to whether they can survive submerged? I bought them submerged in a lfs and they are sprouting water root as you can see from the pics

There isn't such a thing as water roots; they won't survive submerged. In a cooler tank with good O2/CO2 they can survive for many weeks, but not for the long term

My althernanthera sessilis started melting after a week so was quickly removed hahah

Hiaz... unfortunately they do have very good color. You can try replacing them with Ludwigia glandulosa, which looks similar. L. glandulosa can get tall though

Sorry, noob here. Can someone help me understand why non-aquatic plants can stay submerge for months without drowning? Plants like cut flowers and dracenas commonly developed roots at the cut stem, but these are usually only bottom submerge to allow respiration by the leaves. How is it that alternathera sessilis looking like an aquatic plant but not an aquatic plant, and can still be soaked in water for months before dying?

[Xiaozhuang]

Many aquatic plants are marginal plants, many of which grow in places that are periodically flooded. Some have adapted to grow submerged, others merely adapted to wait out the flood. Plants do store food in their tissue, others may go dormant.

Thanks for the explanation. So I could try to adapt my A. Sessilis to become submerged? Something like converting it from emerse to submerge?

Help identify this please?
