Let's see, it might help to know what kind of
snails folks have.

ramshorn (or orb snail), little pond snail (lots and lots
of these), pointed
winkle and japanese trapdoor.

yep yep huh? yep. (Don't know what a pointed
winkle is.)

I've made an effort, when buying plants, to collect
different types from the
growing pond.

No fish disease noticed.

Ditto. But I only have minnows and common
goldfish/comets/shubunkin. I have had fish die
(not recently), but have no idea what caused it.

I feel nursery snails are safe. Snails from the wild I
don't think I'd bring
into my ponds. I've never added plants from the wild into
my pond except by
seed (cord grass, cattails and rush) or birdy business
(bladderwort).

Except for the Japanese trapdoors, which I
bought on purpose, all of my snails have come
in on plants purchased locally. If they're
diseased I haven't noticed but not sure what
to look for.

kathy :-)
