E. major (now called E. martii) produces adventitious plantlets on the
flower stalk. The flowers can be pollinated and will set viable seeds.
Usually, there are enough adventitous plantlets to satisfy one's desire for

I have never heard of guppies eating plants, and I keep guppies, and have
never seen them do it. What about tha alternative hypothesis that the
plants are dying back from some other cause? It is not normal that plants
uproot themselves. Cabomba is not an especially easy plant to keep, and
the lower parts of the stem may be dying, allowing the rest of the plant to
float to the surface. Vallisneria can sometimes send out runners where the
little plantlets do not get rooted well, but I have never seen an
established plant come up by itself.
