    Can take closer picture? Looks more like alternanthera sessilis to me from your picture. If they are indeed sessilis, then you shouldn't be surprised that they are not doing well. Cos these are bog plants.

    I knew something is wrong with this plant... picked those up in seaview. It was sold submerged in a small bags.

    The plant you mention does have a small buds/flowers growing at each nodes where the leave grows. It seems very simila to what i have... maybe it its alternanthera sessilis...

    How long have you kept this plant? Maybe you have to wait abit longer for the plant to acclimatize to your tank water parameter. Try to monitor the condition of the new leaf.

    There is no label of the plants sold at seaview. Looking at the newly developed leaves it does not look like alternanthera reineckii.

    Did a google check on alternanthera sessilis and it is not a true aquatic plant and eventually will melt. That may explains why this plant is not adapting well in your tank while the rest of your plants are flourishing.

    It's a sessilis. Will last quite a while submerge and may even grow for a while.
