Here is a start of a list for cold water fish.

The most common coldwater fish is the goldfish, followed closely by it's larger counterpart, the Koi. However there are many other interesting fish that do not require a heated tank. Many coldwater fish are large enough that are only suitable for ponds. However, can be kept in adaquate aquariums.

Barbs - Several readily available species of Barbs are tolerant of temperatures into the mid sixties, or even lower. All are easy to care for, and are suitable for a community aquarium. They include: the Gold Barb (Barbus schuberti), the Green Barb (Barbus semifasciolatus), the Rosy Barb (Barbus conchonius), and the Two Spot Barb (Barbus ticto).

Bloodfin Tetra - Both the standard Bloodfin (Aphyocharax anisitsi), and the False Bloodfin (Aphyocharax dentatus) tolerate temperatures as low as the mid sixties.
Bloodfins are offered in many pet shops, are easy to care for, and are quite hardy. They are active top dwellers and are best kept in schools.

Buenos Aires Tetra (Hemigrammus caudovittatus) - Easily found for sale, they will tolerate temperatures into the mid sixties. Standard varieties, as well as albino variants can be found. Like the Bloodfins, they are undemanding and easy to care for. They are suitable for a community tank, but will eat live plants voraciously.

Croaking Tetra (Coelurichthys microlepis) - Not often found for sale, they are an attractive fish that is worth shopping around for. Like other coldwater tetras, they are easy to care for and are suitable for community tanks.

Guppy (Poecilia reticulata) actually just about all guppies - As readily available as any fish, there are many attractive variations of this popular fish.

Hillstream Loaches - Although they are not often seen in pet shops, some species can be found for sale from time to time. Not all of them prefer cool temperatures, but most will tolerate temps that fall into the mid to upper sixties.

Native Fish - A variety of North American native fish are now being sold in the aquarium trade. Virtually all of them tolerate cool water. Availability varies from state to state, as do laws regarding which species may be legally kept in home aquariums. Keep in mind that some will become too large to keep in a standard aquarium.

Pearl Danio (Brachydanio albolineatus) - Like the zebra danio, this fish is very hardy and easy to care for. It will tolerate temperatures into the mid 60's without difficulty, and is easy to find. They are larger than zebras, but need not be kept in schools.

Weather Loach (Misgurnus angullicaudatus) - Readily available, this loach is one of the easiest to care for. Couple that with the fact that it will tolerate temperatures into the fifties, and it makes an excellent candidate for a coldwater tank.

Wimple (Myxocyprinus asiaticus) - Also known as the Freshwater Batfish. Not commonly found, it is an unusual fish that is worth tracking down if you like to have something unique. It will tolerate temps into the mid sixties.

White Cloud Mountain Minnow (Tanichtys albonubes) - One of the easiest fish to care for, a new gold colored variant has become very popular. They do best in cooler temperatures, although very low temps will lessen their attractive coloration.

Zebra Danio (Brachydanio rerio) - Outside of goldfish and the guppy, the zebra is the most readily available of all coldwater fish. They tolerate temps that fall into the mid sixties, and are very easy to care for. Long finned species are available, as well as a popular leopard spotted variety.

There are many other coldwater species I could cover, but the above list should give you enough options to get started. Good luck with your coldwater aquarium.

Buenos Aires is an incredible town; it's an amazing metropolis that seems a bit like Europe, but having an edgy Latin American pose and if you wish to visit this town then have a look with hotelbye . El Puerto Madero is just a place properly visited. It offered as the key port of Buenos Aires during the late 19th century but know is turned into houses that could be applied as residences, restaurants, shops and different organizations and to provide that task a little bit of style, all streets in the section were named following women. Strolling through the Puerto Madero is a great way to invest a nice morning the same as visiting El Obelisco. El Obelisco was integrated 1936 to observe the 400th wedding of the city founding and now could be a must-see place from Buenos Aires.

Goldfish or koi like cold waters... but unfortunately they are a bit nasty... Haha !
If you don't want to have to change the water every three days nor every week-end, you can choose the cichlydes... but they are smaller than golf fish.
You can also choose any other cold water fishes, just ask into a pet shop... they would be able to inform you about the best fish to choose.
Personally, I have bought one three-coloured goldfish a few two months ago and as it seems to feel lonely I bought it two friends (a koi and a red goldfish)... of course, I have to change the water each Saturday but finally it's not a problem, it gives me a thing to do.

you can put goldfish in a cold water aquarium, as long as it has some declorinator in it. Most other fish(like saltwater and freshwater fish require a certain temperature. So you would have to keep a thermometer in the aquarium. but just regular goldfish you have nothing to worry about.

Goldfish are really the only fish for a cold water aquarium.Some people say Betta's but they will do much better with a heater.If you get goldfish remember they need plenty of room and I wouldn't get less that a 20 gallon aquarium.

Go fishing like I did. Not on purpose of course, it was the only fish that made it home alive in the bucket and we couldn't kill it ourselves. the bad thing though is it ate all of my store bought fish. He is a Pumpkinseed Bluegill and his natural beauty is outstanding. He loves to eat goldfish and Rosy Reds. Also eats waxworms and Tubi-flex worms. He is in a 29 gallon tank and the heater is broken. He's fine in the cold water.

Do not get a betta for cold water. They're tropical and just like other tropicals need 78 or so degree water.
