There are so many possibilities when it comes to choosing a marine aquarium system to set up. There are biotopes of varying current, lighting and food availability; specialty tanks emphasizing one species or a group; and breeding tanks for producing specific algae, invertebrates or fish. What are often left out of these choices are the nontropical possibilities: cool- to coldwater setups. After all, the majority of the world’s oceans are not tropical. What’s more, United States aquarists have two coasts to choose from with a plethora of life forms to enjoy and study. Here, we’ll explore the basics of what it takes to have a “local” coldwater system with animals from the West Coast, including gear, setup, fixing common problems and choosing livestock.

So, you’ve decided you want to have some coldwater fish. I’m not going to go into detail about tank s right now, but I’ll write a post about selecting an appropriate tank soon. Tropical Fish Centre - The “cold water tank” : Alternatives to Goldfish

The goldfish is usually classified as a coldwaterfish, and it can live in an unheated aquarium. Build-up of this wasteto toxiclevels can occur in a relatively short period of time, which is oftenthe cause of a fish's sudden death. It may be the amount of ,not the water volume, that decides how many goldfish may live in acontainer, because this determines how much oxygen diffuses anddissolves from the air into the water; one square foot of water surfacearea for every inch of goldfish length. If the water isbeing further aerated by way of water pump, filter or fountain, moregoldfish may be kept in the container. Goldfish may be coldwater fish,but this does not mean they cantolerate rapid changes in temperature. The sudden shift in temperaturethat comes at night, for example in an office building where a goldfishmight be kept in a small office tank, could kill them, especially inwinter. Temperatures under about 10 °C (50 °F) are dangerous togoldfish. Conversely, temperatures over 25 °C (77 °F) can beextremelydamaging for goldfish (this is the main reason why they shouldn't bekept in tropical tanks).

A: I guess I did not include tank cooling info in my cold water fish page. First, I would not worry about any sunfish getting too hot. They rarely die from the heat. Obviously the "chillers" made for lobster and trout tanks are too expensive and really too cold (usually 45 to 55 F) for a 10 gallon tank. The fan method you're using is good. Forget the ice cubes. Ice cubes bounce your temperature up and down like a yo-yo and encourage ich infestations. In bait shops, they will trickle in continuous cold tap water or more likely use spargers for their minnow and crayfish tanks -- not really practical for civilians. Numerous airstones would function similar to a sparger. Or you could position your tank above your central air conditioner outlet. But the most practical solution for most people is to just move your tank into the basement. LA Kevin Abercrombie, Rochester, NY, August 10, 2010
Good morrow! Long time fan, first time emailer, I've been visiting your webpage for quite some time. I've learned a great deal about fish for my aquarium from your website, I owe a great deal of my healthiest and happiest fish to you guys however, I have seen nothing about the most daunting task for a large population of the United states, how to keep to keep a tank cool? I only have a small 10 gallon tank with a sweaty pumpkinseed sunfish that requires colder water, and with the summer months here in Rochester, New York (yes, it does get mighty hot up here, 85 degrees is the average this month) the lid leaving, fan evapo, ice cube dunk tank method is not quite cutting it in my tank. Can you please add an expert's guide to cooling an aquarium on your website it would be more than greatly appreciated.
Sincerely,
Your #1 Fish FanEvery type of coldwater fish i could find locally in uk. The main types of cold water fish available in th UK i have in my tank. I prefer to keep a coldwater fishtank (unheated water), but it is limiting to what kind of fish you can keep. I wanted a mix of colours i did also have a silver orf which jumped out the tank and is in heavan, so rememebr always have a good fitted fish tank lid. My tank is a 3 foot fishtank, with sand fake plants and a real bogwood which makes the water a little yellow my fish perfer. i little dirty water is better than clean as the waters they would live in the real world would be dirty. i havehad for about 2 years now and am still hunting for more fish types to add i have 8 fish in total in this tank 4 bigg and 4 small
