Dwarf hairgrass is a great foreground plant for those looking for a taller cover than traditional carpet plants. It spreads readily via runners when kept under good light with proper nutrients and can become quite invasive unless tended. Due to its fine leaf structure it does have a tendency to attract algae, so water conditions need to be kept in line. Trimming the shoots will promote faster lateral growth via runners. Travis

As woffenn said, I'd add too that if you run a black out it will suffer badly and brown off much worse than any other plant I've kept.

I thought to develop this as a carpet early in the tank's life. I recommend making sure water conditions are great first as I've seen diatom, hair, and staghorn algae attack and all are annoying to remove from the hairgrass.

is it OK to have this in your tank when you already have corydoras?

What I wish I knew before I got this plant was exactly how long it takes to spread. It can take a long time to spread, like 6 weeks. Otherwise it grows vertically great in my tank

This is an awesome plant! Takes a long time to grow tho. I realized I shouldn't trim it as often as I trim my other plants because it looks great when it grows longer.

At what point should I grow this plant submerged?

Ive had such a hard time getting this to grow properly, if at all. I bought a brand new bunch for a new tank that has finer substrate. Im really hoping this grows!!

I think getting a successful and quickly grown carpet with this plant involves high nutrient substrate. I had this in a high light pressurized co2 tank with just eco complete and seachem root tabs and it has hardly spread after months. I put some in a newly set up tank with diy co2, medium light, ecocomplete and MGO and it started spreading within a week.

It choked my ludwigia. I used it as a midground plant, and it was ruining everything. I divided it and give some to my neighbor.

Does this spread faster if it's split up into several bunches? My LFS said not to worry about this, that it would spread, but I have read elsewhere that breaking this up can help.

just break it up into about 4 bits from the bunch you get from the lfs I find this guys grows fast with diy co2 and liquid fert sand or 1-2mm substrate seems to work well (i dont have access to the lovely soils you can get hehe) Just get yaself some generic tweezers and just keep a eye on the runs and make sure they stay in the sand/sub

I had a diatom problem with mine and ended up pulling it out to clean it up with a toothbrush. That worked reasonably well but then I got some small plecos that eliminated the problem completely. They do a great job cleaning each and every shoot.

Dwarf hairgrass, Eleocharis acicularis, also called "needle spikerush", has possibly the largest range of all the many native hairgrass species in North America. It can be found in freely scattered pockets from northern central Florida all the way to the Yukon in Alaska, with some of the highest density of E. acicularis occurring in New England and areas of the mid-west, as well as the West coast. However, it must be kept in mind that specimens of the same species that are native to vastly differing climates may not adapt to the same conditions, as in a plant collected from near the Arctic Circle will be less likely to appreciate a warm, tropical aquarium than one belonging to the same species, but collected from Alachua County, Florida. But with that said, there are no legal concerns regarding Dwarf Hairgrass in any state, so go out and collect some from "your own backyard" and give it a try!
