any help please?
I believe the e. acicularis grows taller than the e. parvula. Not sure if there are any other considerations (appearance, lighting needs, etc). Depending on the depth of your tank and the scape you have in mind, you'd want to choose the variety that best fits the image.By the way I see there are 2 kinds of dwarf hairgrass one is Eleocharis acicularis and the other one is Eleocharis Parvula. Which one better or is it just the same thing?
