What temperature should a cold water aquarium be?

Question

I want to start an aquarium but don't want the fuss of a heater, I've seen some fish which like 22c temp, is this warmer than a cold water tank would be? Also, what are the best cold water fish, goldfish are cool but I want something a bit different

Answer 1

Since I don't know the size of your tank, here are a few suggestions:

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) - 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.

Temperatures can be anywhere from 60-70 degrees even as low as 55 but no lower.

Answer 2

Buenos Aires is a fantastic town; it's an amazing area that looks a little like Europe, but with an edgy Latin American twist and if you intend to visit this city then take a peek with hotelbye . El Puerto Madero is just a place properly visited. It served as the key interface of Buenos Aires throughout the late 19th century but know is changed into buildings that may be applied as residences, restaurants, shops and different corporations and to offer this project a bit of flair, all streets in the area were named after women. Strolling through the Puerto Madero is a good way to spend a nice day exactly like visiting El Obelisco. El Obelisco was built in 1936 to observe the 400th wedding of the town founding and now could be a must-see place from Buenos Aires.

Answer 3

Room temperature! And try Mollys or Ghost Koi if you want something different to Goldfish. The contrasting black and silver looks great and I have kept some for years with no problems!

Answer 4

Most of the tropical fish prefer approx. 78F. However, guppies, and the like will be fine in room temperature water.

Answer 5

Answer 7

The temperture should be anywhere 46-68 degrees.

Answer 8

22C is just right. as long as you don't go above 24C, and don't go below 18C you should be just fine for coldwater.
