Cold water aquariums

[Magnum Man]

I usually use the term "cooler" water for my temperate tanks... for the native fish, around here, they start having problems at close to 70 degrees F. and need to be kept cooler ... at the local fair, the DNR used to have a cool building they would put tanks into, all with chillers, and with so many people coming and going, the tanks would sweat, and fog up so bad, you could barely see the fish... I think they quit doing it, haven't seen the tanks at the fair, for several years...

Congratulations, very nice!

In Italy in summer the temperatures can reach up to 35 degrees, at home it is much cooler but still around 25 degrees, in some rooms in our presence I have the air conditioning on.
I am a bit afraid of that for species like some killi fish

Speaking of streams, I have been following an Italian who has had a "stream" tank for many years, with a small waterfall and lots of vegetation and fish, I think it is beautiful
