They like cold water so shaded water is likely to be colder. Slightly o/t I
used to work in a brewery back in the 70s. There was a large redundant wort
(brew) cooler there which was probably fitted in the 1880s and disused since
the 40s. It was much like a radiator with cold water pumped over the fins
which were open to the elements, from a tank about 5mx3mx2m , totally
enclosed with just an inspection hatch. This was full of small fish. Only
way they could have come in was either put their or via birds landing on the
cooler. What they ate (each other? ) was anyone's guess. Pete
