Water lenses are small plants (the smallest blossoming plants at all ?)
which swim on the water surface (which makes it easy remove some if
they are growing to well. they also reduce light and take nutrients
out of the water.) I think the latin name is _Lemna minor_.
I have also _U.gibba_ but did not dare to put it into the same aquarium.
There is probably no obvious reason for not doing so except that the
current setting is working so well and I do not want to change anything.
:-)
Aside daphnia and aldrovanda also snails (sorry not identified yet .-( )
are thriving well. Any idea if they can be dangerous for my aldrovanda ?
