>>>What is worrisome, is that anyone is keeping hydrilla
in an aquarium. It is on the Federal noxious weed
list and should be destroyed. It takes just a
fragment of this plant getting loose in an aquatic
system to begin to destroy it. This is one plant that
definitely made its way into your waters from fish

>>>Hydrilla is a beautiful plant -- that's why its here. It was imported as
aquarium plant. But, its quite dangerous -- even tiny fragments can survive
and reproduce. Its quite conceivable that a few leafs could get pulled out
with a water change, and establish elsewhere. There are so many other
plants that resemble Hydrilla fairly closely and do not have such invasive
natures that I really think it worthwhile that the tank-keeper consider
destroying the hydrilla and swapping to another species. Hydrilla is
probably the most destructive aquatic plant in the US.<<<

Klaus and Joshua --

Sorry - I should have explained - the hydrilla was being cultivated in a
greenhouse for experimental work. One of the groups in our organization does
fulltime research on nuisance aquatic plants. They cultivate plants to
evaluate effects of insect- and fungal-controls. They also observe rigorous
protocol to ensure that no plants escape.
