Good to see an e-mail from you... I agree with your point on Hydrilla.
Hydrilla is a beautiful plant -- that's why its here. It was imported as an
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.
