European themed aquarium.

  • We are currently upgrading MFK. thanks! -neo
I'm dead positive that a cool-down is beneficial, maybe even required. It's the amount of cooling that I question. Our Yellow Perch are also big favourites for icefishermen; but it's easy to catch them in summer in warm, weedy bays as well.

They are, of course, separate species, even if closely related.

Our Perch are lumped into the broad and unscientific category of "warmwater" gamefish, along with their close relatives Walleye and Sauger, as well as all the Sunfish family (including the Black Basses), all the Pikes (Pike, Pickerel and Muskie), Catfish and probably others. "Coldwater" gamefish are basically Trout, Salmon and Chars; can't think of any others in that category.

I know, they aren't scientific designations, but they do more or less illustrate preferred temperature ranges.

Where I live you have to have a permit from Fish and Game if you intend to keep local trout, etc. Is that not the case for native fish in the contiguous US / Canada?

The regs are different in each of the 10 Canadian provinces + 3 northern territories. Perhaps one of our American friends can correct me if I am mistaken, but I believe that each of the 50 states also sets its own fish and game laws as well.

Where I live, all I need is a fishing licence.
 
I just noticed how much fish in the US resemble and are more colorful than fish we keep from halfway across the world.

For example:

longear/pumpkinseed/green sunfish --> resemble texas cichlids, jewel cichlids, jack Dempsey, green terror
redbreast sunfish --> fire mouths
black crappie --> cuban cichlid, Haitian cichlid
warmouth --> jaguar guatopes
yellow perch --> peacock bass
 
When I was 14 or 15 I was being steered around some of the hobby's deepest darkest pitfalls by an elderly gent who was one of my dad's friends. He was into a lot of different fish, mostly livebearers and cichlids, and had breeding pairs of Texas Cichlids and Jewel Cichlids. He was very proud of those beautiful fish, and I admired them too, but...in my mind they didn't hold a candle to the Pumpkinseeds I had in one of my tanks at home.

My dad mentioned to his friend once that I...and he...preferred the Sunfish to the old pro's cichlids. What? Blasphemy! The Jewels were from deepest darkest Africa; they had no equals living in the nearby creek...it was unthinkable!

Except the sunnies were not equals; in terms of colours, they were clearly superior. When the old guy finally came for a visit and saw my fish, he was dumbfounded. He insisted on accompanying my dad and me on our next fishing excursion so that he too could obtain some of these marvelous creatures. He had never been fishing before, and so had a lot to learn...and thus I, a mere stripling, became the teacher.

5 or 6 years later, Star Wars came out...and I realized that I was Luke Skywalker, teaching Yoda how to do mind tricks. :)
 
The problem with a lot of European fish is the water temperature. They need cooler or in some cases cold periods that you normaly cannot provide in your home. Some need permanetly cooler water. Some people manage to provide these temperature in their basements but even there its often too warm on the long term. For example Perca fluviatilis needs winter temps below 6°C / 43 °F and can't stand above 20°C / 68°F for longer time periods.
that is from your books you had read-only theory...

in fact, you can keep some types of European fish even at room temperature all year round. For example, in an unheated room in winter, they will have a colder phase...My european fishes have now 16 degrees of celsius in winter-i have that aquarium in unheated room.This is cooler phase.And in summer it can be also 28 degrees of celsius.But your right that summer is critical phase for european fishes...Some fishes survive and some die ...Due this problems you have to choose not many fish for the tank, smaller species and hardy species...
I have now gudgeons, nase, stone loach, minows, dace,spiny loaches without problems for two years...
