This was the only low light ground cover my legs had in stock and it is t one I’m familiar with so I was curious if anyone could ID it so I could figure out its needs.
Would have my vote too.It looks like hydrocotle tripartita or similar to me. It can be kept low or allowed to get taller as yours is doing with that 1 spot. If you want it low just pinch off the taller part or let it grow tall. It "can" grow with lower light & no co2 but is better with higher highish light & co2. Be very gentle when vacuuming near it, it's a bit fragile but pretty.
