Captured in the wild from Dale E. Maffett
Reservoir.
Origin. You can
find hornwort in many Iowa ponds and lakes. In a few lakes, it grows so
thick, it impedes boat traffic. You usually find it at the surface.
Because it has no roots, hornwort floats. In cooler weather it
sinks. In the wild, hornwort’s tiny leaves harbor any number of
wee beasties that you may not want in your aquarium.

Baby Saver.
Fine leaves and dense growth make hornwort an excellent safe harbor for
baby livebearers. Fry swim in there. Larger fishes try to swim
in there with less success. Fry also eat the microscopic animalcules
that thrive on the hornwort leaves.

Eggs all over this hornwort.
Egg Saver.
Egg scatterers also find hornwort makes an excellent egg-laying site.
Sticky eggs adhere to the leaves. Non-sticky eggs get caught in the
tiny leaves. Parents and other egg-eating fish eat fewer eggs when
they have trouble seeing them and getting to them. Unfortunately, small
snails use the same technique to hide their eggs. Some people
dislike the small snails because
“they took over my tank.”
Actually, those snails eat up all the extra food these people keep pouring
in there. Less food = no snail population explosion.

Décor. Most
hornwort fans use it because they like the way it looks. And hornwort costs next
to nothing.
LA
You can decorate a 10-gallon tank for about $3.
Just drop a weighted hornwort bunch at each end and voila ... you
have a decorated natural tank in under 60 seconds. By disassembling
a bunch of hornwort and arranging the strands in different lengths, you
can make your décor look even better.

New hornwort just arrived from a hornwort farm -- probably a ditch down
south.
Temporary.
Many plant keepers consider hornwort a temporary or fill-in plant.
Hornwort grows incredibly fast so any arrangements are only
temporary. A hornwort stem reaching only halfway to the top will
likely grow to the top by Tuesday. Six-inch strands easily grow to
three feet long in a 10-gallon tank. This plays havoc with your
décor. But little baby fish and spawners love it.

Stretched out it measures circa five feet.
Easy to Grow.
New aquarists find this the perfect plant. Under nearly any type of
lights, hornwort survives and grows. Under bright lights, it grows
as much as an inch per day. It sucks out fish wastes faster than
fish can excrete them. Carbon dioxide, ammonia, nitrites, nitrates,
and phosphates all go into that fast-growing foliage. It sucks all
the nutrition out of the water in six to eight weeks and will often die
unless you fertilize it. But in the meantime, hornwort keeps new tanks
healthy as a horse without West Nile Fever. Under bright lights, hornwort growing tips often
turn reddish.

And then it dies.
Dying Hornwort.
What causes hornwort leaves to fall off? Copper (many medications contain
copper) kills it in hours. Most algae killers take just a bit
longer. Starving takes much longer. So what do you do? Change the
water and switch to anacharis.

What a mess
Leaf Removal. When
hornwort leaves fall off, you get a mess of decomposing plant material that looks
terrible. It can also kill your fish if you leave it in there to rot. Get
out your net and start scooping. By swirling your net in a figure-eight
pattern, you can get most of this junk out in three minutes. Then gravel
vac your tank floor.
LA
Nice looking plant.
Last Word. Still,
for an econo natural look, you cannot beat a healthy bunch of hornwort. LA
