Monosolenium tenerum is a naturally rare
sinking liverwort native to Asia. It was introduced
to the hobby by Tropica as Pellia endiviafolia in 2002 and immediately became quite popular. Only later was it discovered that the plant is in fact M.
tenerum. Although it is available commercially in the
rest of the world, it remains a plant best obtained
from other hobbyists in the United States.
M. tenerum could be described as a larger,
darker, sinking version of Riccia fluitans. It is not difficult to grow and does well under a wide
variety of conditions. However, it will grow much
more robustly and look far more attractive in setups
with ample light and carbon dioxide. It has no
apparent sensitivities but does tend to do better with moderate temperatures and a generous level of
M. tenerum can be propagated without
any problems through division. Of more interest
and concern is the method of pruning. Unfortunately,
M. tenerum does not attach to any substrate
particularly well. While it can be simply turned
loose in the aquarium (where it can become a major
pest), it is far better to contain it in the same way
one would Riccia. A good way to do that is to pile some on a flat stone and wrap with hairnet or thin fishing line. The finished product may not look nice at first, but will soon grow into an attractive and uniform shrub that can be easily trimmed. It is recommended that this be done outside the aquarium if at all possible. If not, try vacuuming excess bits away while trimming. Because M. tenerum is a popular hiding place for shrimp, be sure to examine the clump before passing some on (laying the whole thing down on a white styro lid works well). If the Monosolenium stone is allowed to grow too large, lower portions can die back. Since M. tenerum sinks naturally, it will
not detach and float to the surface like Riccia.
M. tenerum is relatively versatile
and can be used for fore and midground plantings.
Its dark green coloration provides a great contrast
with lighter green foreground plants like
Glossostigma elatinoides and Eleocharis parvulus. It
looks good interspersed among such plants as variably
sized hedges. Alternatively, it can be used as a
true foreground plant, although that use is probably
best reserved for larger tanks.
