Moss/plant in my viv ID

[jett862]

I picked up some bags of this light green stuff at a petstore for a few bucks each; they sold it to me as javamoss, but what exactly is it?

I was under the impression the DARK green stuff I have growing next to it is java moss, this other thing doesn't really seem all that mossy, and I'm doubtful it will grow semi-submerged as I have it.

Thanks.

Looks like a Riccia species....maybe Riccia fluitans. It is actually an aquatic liverwort, hence the lack of resemblance to moss. It's semi-aquatic, and should grow ok at the water's edge with decent light. Aquatically it usually requires intense light and CO2 supplementation.

HTH,
