My brother-in-law has a nice bottom drain with 2" pipe that outflows
to his skimmer. A few weeks ago he was checking the skimmer and found
a fish that had disappeared 4-5 months before.

It had apparently been living in the 2" pipe all that time and had
finally ended up in the skimmer.

When I had a mix of goldfish and koi, it was not unusual for me to
find a small goldfish that had gone down the bottom drain to the
filter barrels and was growing faster than the ones living in the
pond. I started netting them out, but could swear some of the same
fish were back the next time I cleaned the filters. From what I've
seen they don't like pipes they can't turn around in and I suspect if
the fish was too large to turn around in the 2" pipe it was really
glad to be rescued.
