Aldrovanda vesiculosa
 The Aldrovanda vesiculosa is
an insectivorous plant of the water life and is called "Mujinamo"
in Japan. It becomes extinct from the Japanese spontaneous generation
place and is meaningful plant of an only currently cultivated. Because
it likes poor nourished water , there seems to be many cases that It is
supposed that it doesn't grow up well with a comparatively well nourished
tank of aquaticplants. It likes an environment of much plankton and water
flea. Accordingly there seem to be many successful examples that it was
sent to the case which soil of a rice field was put in, and was brought
up outdoors. It likes high water temperature comparatively (25-30‚b).
I cultivate this plant in a water tank between
several years however (now in the
tank of tonina sp). This tank is filtered with Fluval 403 by size
60*45*45 cm. The water is pH=6.0, GH=0-1, KH=0-1, conductivity=130-150
microS. Although the Aldrovanda vesiculosa grew up to 52 cm in a water
tank by my thing and time, there is the time too when a thing of 5 cm
has become only three of them. It is perfect to
spend water flea to cultivate it in a water tank, but isn't always need.
This insectivorous plant eats snails too in a water tank. The supplying
of nutrient of degree that is an cultivating with the water tank which
isn't of any plankton and water flea will be necessary even if it is said
that it likes water poor nourished.
