looks like moneywort but better photos would help

can you pull it out of the water or zoom in more? kina looks like bacopa but the seem looks too thin.

okay, I snapped another pic. I think I take the worst pictures ever. . . but ya'll should be able to see it a bit better. . .oh yeah, it's about 4 inches tall.

Something about the leaf shape seems odd for bacopa, but it's my best guess.

The stem and leaves are to then for bacopa.. Perhaps some sort of ludwigia?

i'd bet ludwigia too

My best ID for ludwigia is Ludwigia ovalis although the leaves just don't seem to be right.

it does have little round leaves, but when I looked up Ludwigia ovalis, I noticed my plant has leaves that come off the stem in pairs, not alternating. The leaf "pairs" also alternate at 90 degree angles to each other, so that if viewed from above and the stem was straight it'd form a cross. And it is growing quick under maybe .5 watts per gallon. When I planted it 10 days or so ago it only had 2 leaf sets. And the leaves seem flatter than Bacopa.

that's why I am doubting that it's a ludwigia species...it doesn't look like other commonly available ones, unless it's an odd cross...but I'm not to well versed on this genus of plants.
