Coldwater, duckweed-eating fish?

[yk]

I'm looking for small (max ~2in) coldwater fish (mid 60's-low 70's F)
that eat duckweed, but not other plants.

I've only been able to find two possibilities so far:

White Cloud Minnow
Zebra Danio

I was wondering if anyone knows if they eat duckweed? Or if there are
similar sized coldwater fish that may?

Maybe it's just a bizarre or crazy idea, but I have a bucket of water
with ghost shrimp, plants (incl. duckweed), ostracod-looking creatures,
and pond snails. Since I can't personally do away with them out of
guilt, I figure I might as well put it in (ideally) a 5 gallon tank
(although that might be a little crowded). At least I could see what's
going on in an aquarium. It's kinda hard to peer into a bucket. :) I'm
looking for duckweed eating fish to keep the duckweed under control. I
don't know necessarily if I want to get rid of it all, but to keep it at
bay.

Although with all the snails I have, maybe I should get a loach... But I
suppose that would require a much larger tank and I don't have room for
that now...

-----------------------
By the way is it common for physa snails to grow larger than 1/2 inch? I
have one that's about that size now. It was a little spooky to see
him/her looking back at me.

It is not uncommon for me to see several snails hanging out above the
waterline. Is this unusual? Are they sick?

I *have* heard of fish that will eat duckweed, thought I cannot rcall at
this moment. Perhaps my old brain will cough them up later.
I can tell you that the white clouds and danios do not, IME, eat
duckweed. I have both, and have never seen them eat it.

Some of the barb family eat duckweed. Goldfish do as well, but I doubt they
fit your size limitations.

Bloodfin Tetra?
(68-80F) 1.75in max

American Flag Fish? Do they eat all green stuff in sight? Do they need a
larger tank than 6 gal? I actually haven't seen them locally...
