What plant is this?

[ralliart12]

You might want to consider Marsilea hirsuta. Mine is creeping slowly over the substrate without CO2 injection.

May I know how do I reliably "force" M.Hirsuta to creep instead of growing upwards? Btw, are its leaves the same size as glosso? What amount of light are you using for your M.Hirsuta to creep?

Railart bro,

Is the plant reaching toward better light source?
Sidetrack: your colleauge very "bright"? It's creeping to him/her lol

mine is creeping slowly too 2wp with no co2 ... their leaves a slightly bigger than glosso but growth rate is slooow in my low tech tank...

...Is the plant reaching toward better light source?...

I wouldn't think so, i.e. I'm providing 32watts for a 4.49-gallon tank, should be considered high light already. That said, there is a row of windows at the direction where they are creeping towards, but that row (of windows is quite far away). In addition, only a few strands are creeping that direction; not all the strands.

It's comments like this (& this) that makes my day. Thanks.

& yes, that colleague is very bright.

Anyway, I'm swearing off M.Quadrifolia for a while; I have had to throw a bunch of them away recently, & there was a thermometer "trapped" between strands of them which I have to use some strength to "tear apart". &, I can lift up my entire substrate by the bunch of them (M.Quadrifolia).

My light is weak so the Marsilea produces smaller leaves and creeps along the substrate very slowly. Prior to this, they were in high light and still creep along the bottom, but produced bigger leaves. The only drawback is that it is very slow growing, at least for me.



That's how bad the lighting is now. I need to replace the tubes soon or the plants are going to suffer.
