Eleocharis acicularis

by Roxanne Bittman <rbittman/>
Date: Wed, 18 Feb 1998


This plant grows very easily and seems to adapt well to tropical
temperatures.  I collected mine at 4000 ft. elevation in cold water
and it is growing well and did so from the beginning.  It reproduce by
runners in aquaria and height is variable and dependent on light
levels.  It only gets to about 3 inches tall in my tanks.

I have seen it for sale at Albany Aquarium in the S.F. Bay Area; it
can't be hard to find.  I have seen it on many plant lists from mail
order dealers as well.

It tends to get very dense and any plant with fine, dense growth seems
to be a magnet for hair algae, at least in my tanks.  Both
E. acicularis and E. vivipara collect hair algae clumps if I
"over-iron" the tank.  I really love the "grassy" growth though and
feel they are great for certain layouts.

I grow A. minima in a 15 gallon with bright light. It gets neither
circulation nor filtration, nor CO2. Five guppies and PMDD ensure
its dense growth. I attribute this to the lighting of 3 watts/gallon. 
How many submersed plants do well without some circulation?

It is found in North America, South America, Europe, Asia, North Africa,
Australia---just about everywhere.  I know a pond near Jackson, MS, where
it lives.  I have had it and it is easy to grow, but it is not tolerant of
dim light.  It has very thin cyllindrical leaves and sends out thin runners
with little bunches of leaves coming up every inch or two.  it is such a
minniature plant that it can do quite well in a pint jar with a half inch
of mud and three inches of water.

Paul Krombholz, in central Mississippi where you can't have basements
because they would either fill up or your house would float away.

The two commonly sold species of hairgrass can be
told apart the following way:

Elecocharis acicularis:  tends to stay short (approx.
2-6"); does not propagate by making new plants at
the top of the plant.


E.  vivipara: grows taller (easily reached the top of my
20" tank) and makes new plants at the top of the
leaves.  These are your "split ends."  

If you don't like the way E. vivipara grows, you can
a)give it a haircut; it won't hurt it, or
b)replace it with E. acicularis.

Dwarf hairgrass

>Hairgrasses (which I have absolutely no luck with) 

I've seen this comment many times. I've heard it from friends too. I seem to
be able to grow it like mad and I'd like to share at least what I can, to
the list about it. The plant is the same one Amano uses (or looks exactly
like which is my main concern). It does fine in lower light and higher
light(2watts/gallon to 6 watts/gallon), FL's MH's PC's, Quartz, etc. It
likes more light and seems to do very well with PC's and FL's lights around
3-5 watts/gallon. Clean water with 30-60% weekly water changes, Kh is 5.5.
Ph has been from 7.1 to 6.6 fish load has been light. Good snail population.
SAE's, Otto's are fine with or without. Slow water movement. 
2-3mm Lapis Lustar gravel. I've added kitty litter with great results(D.
Quackenbush) and also laterite in the past. Old gravel works great. I've
used RFUG filters on the tanks that do the best
and this should be noted. I use PVC pipe and make a grid with holes drilled
in the bottom like a spray bar for the entire bottom surface. These work
much better than plate UG's for planted tanks. Flourite only(no RFUG) test
haven't  been done yet. Seems to be doing fine so far but I haven't tried to
do a good patch in a Flourite only tank. The round 2-3mm sand seems to be to
the plant's liking more than anything. Fertilizer type doesn't matter as
long as it has something along the lines of Kent/Sera/TMG in it. Lighting
duration about 10-12 hours daily.
Temp from 84 to 76 with 78-80F being a great range.
The plant does seem to do extremely well under PC's 6700K and also Quartz
and FL's( a cool white+triton) at about 16" depth or so.
Sinking Riccia can infest the patches of grass and the battle will ensue. I
gave up on trying to remove it (Riccia) all. For those that aren't having a
good time getting their Lilaeopsis  lawn going perhaps they might consider
this plant instead. I believe the effect might be more to your liking than
the Lilaeopsis. Easier to prune IMO too.
