I have a few moneyworts in my 20 gal planted tank. After a while they
all seem to rot in the section of the stem closest to the gravel.
Other than that one spot, they all seem healthy; solid green stems and
leave, white roots growing from the stem (are they roots? if not what
are they?) I have a 6700K 65 watt flourescent light so I don't think
lighting is a problem and I haven't had any problems with any other
plants. Any help would be appreciated. Thanks!
