1 rhizome of Anubias nana barteri
Anubias nana is a
beautiful African plant which grows roundish, dark green leaves from small stems
that branch from a rhizome. Its thick roots grow downward from this rhizome.
It is a very slow grower and the leaves can last for several years.
However, because of its slow pace, it is often prone to algae growth on the
leaves. Keeping the plant shaded will sometimes avoid this problem.
Nana is best placed on a rock or piece of wood, using fishing line or
cotton thread to hold it down. Unlike Riccia, which will not attach itself over
time, Nana will become attached to the surface it is planted on. Therefore,
cotton thread will work since by the time it disintegrates, the plant will be
firmly secured via its own roots. It can also be laid to rest against the top of
the substrate (using an aquarium safe metal weight to keep it down) so that the
roots can seep into the substrate but the rhizome will stay out of the gravel. The rhizome must not be buried or it will rot
Anubias nana is a good choice for low light aquariums since
it can live in less than one watt per gallon of light. Its growth will be very
slow, but it will thrive nonetheless. It also fares well in higher light
aquariums although care must be taken to control algae since its leaves are very
prone to it. CO2
is not necessary for this plant to do well, though with all
plants, the addition of CO2
will boost the growth rate, especially when coupled
with higher light and a good nutrient base.
Propagation of this plant
merely involves making a clean, sharp cut through the rhizome, taking care to
leave enough leaves and root system for each new clump. Also, removal of old
leaves stimulates new growth.
The leaves of this plant are very thick
and tough and are generally not eaten by herbivorous fish.
This plant is
also a good candidate for emersed growth and tends to grow faster when emersed.
Because of its small size (only growing a few inches tall) and its
outward, rather than upward, growth, A. nana is suitable for the foreground or
midground of medium to large tanks, and can be used as midground in smaller
tanks. For much smaller tanks, a better option may be the ?dwarf? form of A.
nana, which is called Anubias barteri var. nana ?petite?.
flowers moderately often in the aquarium, producing a soft whitish green
