This is Infopimp's tank and I'd like to know the name of the grass on the right side. Thanks!:)

O.O i think its not grass but moss from too much light?
the left maybe HC?

[Kosmos]

Almost looks like the moss they make moss balls with.

[Frigo]

I think is Cladophora rupestris, but I am not sure :P or Cladophora aegagropila ... extended like Kosmos said
:D

[adrianng1996]

maybe hairgrass?

[Kosmos]

maybe hairgrass?

Definitely not hairgrass.

The picture is a bit fuzzy, but it looks like algae (clado, as some have pointed out).

Thanks for replies!

I think it is Cladophora aegagropila. :)
