Looks like primrose-willow (Ludwigia glandulosa), considered a difficult to grow high light plant.

Perhaps it needs a suitable temperature to grow in. High light plants wants MH intensity to thrife? I have some plants that I dont know at first which are considered very difficult to keep by tropica due to high-very high light demand. Accidentaly I managed to grow them like wild with pruning and all. However some looks a bit different with a bit longer internodes compared to when I bought them. I guess they are still hungry for some more light (perhaps an addition of big PC on several spots will help).

With that amount of lighting over a 10g, you're definitely going to need a full dosing regime. KNO3, PO4, and micronutrients. Since you're running the Seachem line, Seachem Nitrogen and Phosphorus would work. I'm not sure how the dosing would work you, but you'll definitely have to dose more than the recommended levels.

It might be ALTERNANTHERA REINECKII as the stems are in the picture seems all red & kidda soft like the one that I have & ludwigia's have kidda hard-greenish stems (IMO). Well I might be wrong. Like everyone said, you have to dose kno3, but then again I have 30watts in my 10g *SHRIMP ONLY TANK* & only dose excel every 2 weeks with flourite substrate as well & it seems to be growing fine. Leave it alone for a while & try to lower your temp (mine stays at 75-78 deg.). What kind of light/bulb do you have in there CF, flourescent, ???

The leaves on your plant look to have an obtuse base with an overall elliptic shape.

The leaves appear to be arranged in a decussate pattern along the stem.

You'd know better (having the plant in front of you) but my guess goes to Alt. reineckii because of leaf shape.

Take care.

IT is ALTERNANTHERA REINECKII, I am 100% sure, my luwig glandulsa does not look like that. It has a darker red too it.

I vote for A. Reineckii too. I received some in the mail two days ago from Toofazt. It looks 100% identical.

I've long struggled with A. reineckii (though many state it to be easy), but might have recently turned the corner. For my setup, I appear to have been underdosing micro nutrients. I'm now dry dosing 1/8 tsp of CSM+B every other day for my 46g. I'm using the middle spoon of the small measuring set, and I did recently test it, and 8 of 'em filled my 1 tsp measuring spoon.
