omenakotiloista

Kumpikin epäilysi saattaa osoittautua oikeaksi:
jotkut lääkkeet todella tappavat kotilot ja
kotilot ovat joidenkin sairauksien kantajia tai
väli-isäntiä. Jos Sinulla on monnisia, niin mm.
kuparipitoiset lääkkeet ovat niille täyttä
myrkkyä, joten varmista myyjältä että käyttämäsi
lääke on monnisillekin harmiton!

My fish have a disease and I want to treat them.
Can those chemicals harm my snails?
The basic principle in combating a fish disease is
to use chemical compounds that kill the disease,
while having no adverse effects on the fish, due
to neurological/metabolistic differences between
the organisms.
However, snails have more in common with many
parasites then with fish in the way they react to
chemical substances. It's thus advised to isolate
the snails in a separate tank during treatment of
the fish unless you are absolutely sure that the
product you use doesn't contain snail-toxic
chemicals. And as many disease causing organisms
do not survive outside the fish during a few days,
together with repeated water changes in the
isolation tank, the risk of reinfection through
the snail reintroduction can be minimised.
Exceptions to this rule are parasites that have a
life cycle with snails and fish as intermediate
hosts (mainly the case with wild-caught
fish/snails). See also here.
A short list with chemicals that are/could be
toxic to snails in therapeutic doses:
-Malachite Green (used to treat Ich or white spot,
fungi and Velvet or Oodinium).
-Various organophosphorous pesticides like
formaldehyde, metriphonate, trichlorphon (= dylox,
masoten, metriphonate, neguvon, trichlorophon),
dichlorvos and others used to treat infections
with flukes, worms, crustaceans and lice.
-metaldehyde used as molluscicide.
-Various copper containing drugs to treat protozoa
and fungus infections.
-Parricide D (Di-N-Butyl Tin Oxide) used to
eliminate helminthes, acanthocephala, trematodes,
cestoda and worms.
A list of fish phamaceutics of several
manufacturers with the active ingredients is
