Cold water fish in tanks

Anyone ever tried this. I guess the main problem would be keeping the water cold enough, especially for trout.


I knew someone who used a Guinness beer cooler many moons ago, not sure how well it worked though.
I had a wee bandie Rainbow in a tank once, it lasted about a week think. I kept Carp, Roach, Gudgeon, Tench and Rudd in tanks(some were used as bait back in the 1970's), I never cooled the tanks.


A pal of mine had an old marine tank that was 72x24x24 that he had stopped using and he kept Brown Trout, Perch and Minnow in it for his Pike fishing. He just kept it in his shed with a small pool heater to stop it freezing in the winter :)
Don't worry, be happy.
Carried it in full, then carry it out empty.

This is my old trout. She lasted a couple of years but I've know idea the age when I caught it. I specifically went to an area where the genetic strain was small in size. I ended up running 4 fans over the water which kept the temperature around 14 degrees. Worked out cheaper than running a chiller unit.


Yes. I prefer the phrase 'temperate' to cold water though. :)

There are a number of chillers available commercially to keep the water cool enough in hot weather. These are mostly used by people keeping native saltwater species though which are a lot more sensitive than freshwater tropical fish.
