Well meaning, but extremely foolish nonetheless. I feel that a lack of
environmental education is most to blame for these kind of things. I also
feel it is highly irresponsible for fish shops to sell fish to folks
without making sure they have tanks/ponds that will hold them as
adults. And hobbyists should thoroughly research a prospective fish before
buying/collecting and buy/collect responsibly. Pardon my preaching, but
this is something I feel very strongly about.

Words of wisdom. Even captive fish collected from native waters should
NEVER be released back into the wild by a hobbyist. This goes for bait
minnows, too. My undergarments get tightly bunched when I see advice to
the contrary.

Interesting question, Diane, and something worth pondering over IMO. My
habit is to toss trimmings/plants straight into the garbage, but it's not
inconceivable that small sprig of something that ends up in the wastewater
from changes might survive and eventually make its way out of the sewer
system. I think the easiest way to avoid accidental introduction is to use
the wastewater from changes to water the shrubs or lawn outside or the
houseplants inside. If the water is going down the drain, straining the
water could help for larger bits as you point out. Putting bleach in the
water before dumping it could help for smaller stuff. I've sterilized
water to discourage introduction of resistant bacteria into the ecosystem
after the (fortunately) few times I've had to treat fish with antibiotics
-- this advice was given to me by a vet friend of mine. I was pleased to
see Julian Sprung mention this same precaution in a recent installment of
his FAMA article (source of method cited to Craig Bingham whom some of you
may remember from his presence on this list). Antibiotic use is taken far
too lightly. Perhaps the water we pour down the drain is as well. I don't
think we can ever be too responsible when it comes to the health of our
environment.
