I have rotalla wallichi and asian ambulia, and currently a new stem plant
that I have not been able to find in any photo and unable to identify, that
all close their tops before lights out. I always assumed that they had had
enough light and so closed after so many hours. Each variety closes the same
time period each night in a given tank. Interestingly, it is different in
different tanks with different lighting periods and setups but the same each
night in the same tank. Don M.
