This is one of the most resilient and easy to keep carpet plants you can find. I had it in a tank that was left totally neglected for several months, with no water changes, fertilization or CO2. Obviously in these conditions it doesn't spread or form carpets, but on the day I finally decided to give the tank some maintenance, under the thick layer of cianobacteria I found this heroic little plant surviving who knows how, and as soon as the setup was in order it began to happily spread again. Under optimal conditions it forms a beautiful carpet, dense and 'hairy', thus the common name Hairgrass. Maintenance of this carpet is quite easy since, with a natural size of only about 5 cm and good rooting in the substrate, it doesn't require regular pruning or reattaching as some other carpets, only that you keep an eye on where it's spreading to since it will easily enter even the most shaded regions of the tank. When I bought this plant (Enrico's carpet above was born out of my own shootings which I sent to friends) it was labelled as E. minima, but after some research I concluded that it should be E. parvula.

Easy to grow, but make sure when you first put it in that you space the little clump a little away from each other. Tends to get covered in a little algae a first, and holds on to debris if the water isn't super clean. Trim it back to get growth short. Nice for the lawn without high lighting.

I bought a pot of Dwarf Hairgrass and positioned it in the middle at the back of my 22 litre tropical tank; I haven't used CO2 or any plant food. It has successfully managed to grow out of the pot and it is starting to spread from the center of the tank and out towards the front. I personally recommend planting it in your tank in a pot; this prevents the grass from uprooting, after the pot has settled it will grow out of the pot and into your tank. Dwarf Hairgrass makes a great place for Glass Catfish to rest, since they like to hide next to plants.

The dwarf hairgrass is a very fast and easy plant to grow, even without a heater or CO2 injection. My only problem with it is that filth tends to accumulate on the leaves, and algae likes to grow on it too.

A warning about combining harigrass with fiddler crabs, they love it. The first time I combined the two, the crab just parked on top of it and ate it strand by strand like pasta until it was completely gone.

When I first bought my Hairgrass I planted it in front of my driftwood. It did not take long for it to start developing root structure and shortly after a few days in direct CO2 flow it had grown really well.
