We agreed Gail has rosy red minnows.

=====================
These minnows are great little fish for keeping the mosquito population in
control for those who don't want goldfish or koi, or who have small ponds.
There were two conditions where they didn't do well for me. One was a
pool out in the full sun that became too warm in summer. It was too far
from the house to aerate and I think the heat killed them as they did die
off one at a time. The other is the 3 barrels beside the iris bed. The
only thing I can think of there is the lack of aeration as the water
doesn't get all that warm in summer. It may have been lack of aeration
alone in both cases.

They did fine in a partially shaded, aerated and filtered in-ground 150g
pool closer to the house. I haven't found a dead one in there yet, but
their population is dwindling. It's the only pond that's not netted so
anything can get in there. One day I found a box turtle on the filter.
:-)

So far I haven't seen any turtles in my yard. I
think we're too far from the nearest creek to get
them. My 2 above ground (stocktank) ponds are
difficult for predators to access. I have seen
bullfrogs around the yard but I'm not sure they get
get into the stocktanks. The frogs I've seen in
there tend to be small green frogs of some sort,
or treefrogs.

The inground pond is about 300 gallons and has
intentionally easy access for wildlife. But even
that one still has a healthy minnow population.

It could be that the snakes - there are rat snakes in
and around my yard - keep the frog population
down. Whatever, I've been lucky in my ignorance!

double tailed fish need warmer water. fish with lots of finnage need warmer water.
I remember Jo Ann's discussing a friend of hers that had really long tailed shubunks
in outside ponds in Washington, state of, and the fins would shred when the temp got
below 60 something.
deep bodied GF need warmer water for good digestion too. altho grazing in a pond
offsets that problem to a great degree.
I have had fancies (not really deep bodied ones) survive in outdoor ponds as long as
there was good aeration and a hole stayed open and the pond was in my greenhouse.
when the greenhouse collapsed I lost almost all the fish. I restocked and one winter
there was too much mulm and they all died. there was always attrition anyway in the
outdoor ponds.
I think it would work even better to cover the pond and drop in a 500 watt heater all
winter, like I do with my koi ... I feed them all winter long, once or twice a week
since there isnt any filter, and the water stays above 50o for all but a month at
most. they are in much better shape than going 6 months without food and their
immunity is down for a very short time, if at all.

This doesn't happen with my long tailed Shubunkins or my double tailed GF
here in zone 6. Veiltails with excessive finnage may be a different matter.
I don't have Veiltails.

How cold are your winters?

when the greenhouse collapsed I lost almost all the fish.

Rapid temperature change possibly?

there was too much mulm and they all died. there was always attrition

Where I live they only go without food for 3 to 3 1/2 months on average. If
the water goes over 50F in winter they're looking for food and are fed
something light like flakes.
