Two More Goldfish Subsitutes: the White Cloud Mountain Minnow, and the Common Guppie

White Cloud Mountain Minnow

Previously, I've posted about other fish that look similar to goldfish, such as Gold Barbs and Rosy Barbs. They look similar to goldfish, but are easier to care for in an aquarium setting (real goldfish being better suited for living in ponds or large pools, or very large aquariums).

But there are two other fishes, that don't look a lot like goldfish, but that are among the easiest to care for in an aquarium. One is the White Cloud Mountain minnow
[...] White Cloud Mountain minnows are considered good fish for beginners, as they are extremely forgiving with regard to aquarium temperature and water quality. They are often sold as ideal "starter fish" for cycling a new aquarium, however it is kinder if they are introduced to an already cycled tank. They are schooling fish, and feel most comfortable in a group of at least five. An individual of these minnows kept alone may become timid and lose its bright color. White Clouds are generally peaceful and happy to coexist with other fish, as long as they are not put in a tank with larger fish that may eat them. The minnows are usually top or middle-level swimmers and rarely swim close to the bottom of a tank.

Although the nominal temperature range for the species in the wild is 18–26 °C (64–79 °F), it can survive water temperatures down to 5°C (41°F).[4] This makes it an ideal fish for keeping in an unheated aquarium in cold climates. In fact, White Clouds are more active and healthier when kept at temperatures lower than those at which most tropical tanks are kept. Water hardness (dH) should be from 5 to 19, and pH levels should range between 6.0 and 8.0. Also, the aquarium should have a top. White Clouds have been known to jump out on rare occasions.

During the 1940s and 1950s, White Cloud Mountain minnows acquired the nickname, the "Poor Man's Neon Tetra," because they were much more affordable in price than the colorful and then expensive Neon Tetras.[5]

Two variants are commonly available: the "Golden Cloud" and the longer-finned "Meteor Minnow." The Golden Cloud is a relatively new variety as compared to the Meteor Minnow. The Meteor Minnow first made its appearance in the 1950s in Perth, Western Australia and the Golden Cloud in the 1990s. Breeding between the two varieties has recently resulted in another attractive fish, the "Golden Meteor Minnow." Inbreeding of Golden Clouds have resulted in "Blonde" Clouds, light yellow specimens similar in colour to blonde guppies and "Pink Clouds", flesh colour specimens which lacks further pigmentation still. [...]

I have a bunch of them, and they've been a very hardy fish, easy to care for, and at their full size are quite beautiful. I have the regular short fin, and the pink/gold ones. I'd eventually life to get the long finned "Meteor" variety:



The Meteor's look stunning, but I've not been able to get them through my local fish store. Darn!

My local fish store sells baby White Cloud Minnows as feeder fish, which means they can be purchased for only 0.20 cents apiece. Very affordable!

White Cloud Mountain Minnow Fact Sheet
[...] This fish is very hardy. It will survive in temperatures ranging from 4̊ C (39̊F) to 32̊ C (90̊ F) although the extremes of this range are not recommended. It is more comfortable at about 16-26 °C (60-72 °F). This is a lower temperature than some tropical tanks although, like most 'cold water' fish it can be kept in tropical aquariums, so it can be kept in either a tropical or an unheated aquarium.

The fish prefer clean water, and will grow and breed over a wide range of ph and hardness. I would avoid extremes of pH or very hard water. Make sure all the Chlorine or Chloramine is removed.

The White Cloud Mountain Minnow is intolerant of Copper in the water, and great care needs to be exercised if Copper is used for treatments. [...]

I read somewhere that, while a bowl is not really a suitable environment for any fish, the White Cloud Minnow might be the hardiest to be used as a bowl fish. But I really would not recommend a bowl; I'd recommend a filtered tank, no smaller than 10 gallons. I think a heater is preferable too, even for cool water fish; it keeps the temperature more stable, which is important if you live in a cold weather climate or somewhere that has very cold nights. I know that my house can get very cold at night in winter.

A bit of trivia about how the White Cloud the fish was "discovered" in China:

White Cloud Mountain Minnow (Tanichthys albonubes)
[...] This fish's ability to survive (and breed) over a wide range of water conditions, temperature and general hardiness means it's cheap and an excellent choice for beginners.

This fish is sensitive to copper in the water so ensure that you do not overdose when using any treatments containing copper and accidentally poison them.

It's latin name Tanichthys albonubes literally means "Tan's fish, white cloud". It was named after a boy scout leader named Tan who discovered it in the 1930s.[1] [...]

I've read too, that the fish is now believed to be extinct in it's original location. But it has survived in captivity and, through the aquarium fish trade, spread all over the world.


The other fish I considered to be an easier-to-keep alternative to goldfish, is the common Guppy. I say "common", because there are many fancy strains of this fish, some of which are not physically hardy, having been breed for their looks more than anything else.



Guppy Fact Sheet
[...] The Guppy is a popular aquarium fish. It can be kept with other small peaceful fish, including Platies, Swordtails and Mollies. It is in the same family as these fish and is in the same genus as Mollies. Other fish suitable as companions are White Cloud Mountain Minnows, Neon Tetras, Cardinal Tetras, Siamese Fighting Fish, Peppered Catfish and other Corydoras catfish, Cherry Barbs, and other small peaceful fish.

[...]

Guppies generally thrive in fairly hard, slightly alkaline, water. They can tolerate very large amounts of salt in the water. In some countries they are bred in water which is a mixture of half fresh water and half sea water. The Guppies thrive in this water, but these fish can cause problems when people put them into normal fresh water aquariums. As well as having to be acclimatised to the fresh water, the Guppies have not been exposed to columnaris disease. These fish can die very quickly in a normal aquarium unless strong treatment is done quickly. To get immunity the fish have to be exposed to the disease, and the disease cured.

[...]

The Guppy is a tropical fish. However, different strains of Guppy have different tolerances to low temperatures. I have even heard of strains that are claimed to be able to tolerate temperature down to 4̊ C (39̊ F). I have never encountered any of these. Once I heard of a creek to the north of Adelaide that was supposed to have a naturalised strain of Guppies. I searched for the creek. I was able to identify the creek from the description I was given. There were no Guppies in it. (Actually, there was not even any water.) Although I tried to find where the Guppies would have gone, I was unable to find any Guppies. I suspect that this was a case of mistaken identity of the fish.

As a general thing I would not suggest a temperature of lower than 18̊ C (65̊ F). Guppies will certainly tolerate up to at least 32̊ C (90̊F), and probably higher. Although I sometimes give the maximum and minimum temperatures types of fish can tolerate, it needs to be remembered that subjecting fish to their limits is not good and you are stressing the fish very badly. Stress will leave the fish very vulnerable todisease.

I generally set the thermostat at 24̊ C (75̊ F) although some people prefer a few degrees higher, especially for breeding.

[...]

The modern Guppies have been selective bred for colour and fin length, as well as other external characteristics. In the process they have lost much of the original hardiness of the Guppy. The life span of the Guppy now is often no more than a year. [...]

The hardiness of the modern Guppy (or lack of it) is a subject of much debate, of which I will post more about later.

I do think some varieties may be more hardier than others. Buyer beware.

I know there are other fishes that might be considered as goldfish substitutes too. The Zebera Danio, for instance, is also a hardy fish that is tolerant of lower temperatures. But I have read, that it prefers a tank at least 36 inches long, because it likes to swim back and forth a lot.

The Siamese Fighting Fish is also considered to be a good bowl fish by some people. But it will not thrive in a bowl, and actually does better in a filtered, heated aquarium (it prefers it's water temperature to be kept around 80 degrees). And it prefers live food. If you keep it in colder temperatures and only feed it dried food, it might survive, but probably won't thrive and have a long life. But if you treat it right, it can be "easy" to care for and very satisfying to keep.

So, if you have been trying to keep goldfish indoors, but have been unsuccessful or found it too arduous, you might want to consider some of these other fish I've suggested. There are plenty to choose from, look them over and see which ones might be best for you to try.

Another Gold Fish Substitute: Rosy Barbs

A while back, I posted about the difficulty of keeping gold fish in an aquarium, and using Gold Barbs as a substitute. I've since found anther aquarium fish that's and excellent choice:


Details About the Rosy Barb Fish
One of the most popular types of freshwater tropical fish is the Rosy Barb fish, which is also known as the Red Barb fish. This tropical fish thrives in large groups, 5 or more red barb members. As a schooling fish, it is naturally sociable and peaceful when relating to its own kind, as well as other types of fish in the aquarium. With this kind of temperament, they are perfect for an aquarium with a lot of inhabitants. Here is more information about the Rosy Barb.

Physical Appearance

The body of the Rosy Barb can be described as tall, increasing width vertically as it gets older. It can be easily mistaken for gold fish from the perspective of novice fish observers because of its color which can range from yellow to red, but the most common coloration is metallic silver. The shade of red in the male Rosy Barb becomes more vivid during breeding time, and this is where the name of the fish comes from. The male is generally smaller than the female and it also rarely displays the color yellow on its body unlike the female. The body size and color may vary between sexes, but both of them have black dots in their tail fin and shiny scales that usually come in the color green and are highly reflective. [...]


The golden variety looks particularly like a goldfish:



The ones I have look more like this:



They remind me of Veiltail Goldfish. Very elegant, very hardy, easy to care for. The temperature range they like can go as low as 64 degrees, which is lower than most tropical fish can go. Real gold fish can tolerate much lower temperatures, but that's one of the reasons they do so well in ponds. So Rosy Barbs are more of a temperate water fish, than a cold water fish.

In the wild they can grow up to 6 inches, but in aquariums 4 inches seems to be the maximum size they reach.

I find Rosy Barbs to be an excellent Aquarium substitute for goldfish.

My Surrogate Goldfish Substitute: The Gold Barb

I did a post earlier about the shocking truth about the common goldfish; about how, when properly cared for, they can live for decades and grow to be a foot long, requiring enormous aquariums and frequent water changes. Too much fuss! They are more easily kept in a POND.

I wanted a SMALL, golden, coldwater fish that would stay small, to be a surrogate replacement for my desire to keep small gold fish. And I think I've found it:


The Gold Barb (Puntius semifasciolatus)
Max. size: 7cm / 2.8inches
pH range: 6 – 8
dH range: 5-19
Temperature range: 18 – 24°C / 64.5 – 75°F
Care Moderate

Common names- Gold Finned Barb, Golden Barb, China Barb

The Gold Barb is a popular fish amongst aquarium keepers. Living between four and six years they originate from the sub-tropical parts of South East Asia and is exclusively native to China, Laos and Vietnam although it has now been introduced to other countries The Bright colours of the Gold Barb and their active personality add charm to any aquarium. This coupled with their ease of care makes the Gold Barb an ideal fish for beginners and experts alike.


Gold Barb are shoaling fish and should ideally be kept in groups of at least six. Living up to six years in age they are docile fish that make a good addition to a community tank when paired with fish with similar personalities and care needs.

It is known by several different names, most commonly referred to in the USA as the China barb.

The Gold Barb belongs to the minnow family, and is a medium long barb. Its body has a complete lateral line and the last simple dorsal ray is serrated. It has a pair of barbels located at the corners of the mouth on the upper jaw. The female tends to be duller than the male and bulkier. During the breeding period, the male golden barb's belly will change colour to a vivid orange.


They are mid to bottom level fish and need a tank of around fifteen gallons or more to be kept happily.

They are very active fish and need plenty of open space with plenty of plants at the back and sides of the aquarium as well as a strong current to mimic their natural conditions. [...]

They aren't as much of a "cold" water fish as a true goldfish, but they can live in an unheated aquarium in a house kept at normal room temperature.

And of course, they get on with other barbs/minnows. I've never collected them before, so I'm looking forward to it.

Wikipedia: Gold Barbs
[...] The Gold Barb, a gold colour variant of the China Barb, is an active, peaceful schooling species that spends most of its time in the mid-level and bottom of the water. Its typical lifespan in captivity is around four to six years. This peaceful green-gold fish is often used in community tanks by fish keeping hobbyists. It breeds readily in outdoor pools and free-standing ponds during summer months, and withstands cooler temperatures better than other tropical fish. However, it does not stand the cold as well as its original plainer China barb counterparts.

Albino variants of the Gold barbs have been produced by Dennis Wilcox in the 1970s in the US. Gold barbs with no black markings have been observed by Stanislav Frank in Europe also around that time. Flesh colour (pink) specimens appeared by 1990s. Tri-colour, ie, black, orange and pink specimens appeared recently. [...]
So there are variations, too. Goody!

The shocking truth about the common goldfish

When I was a kid, I got my first goldfish at a supermarket givaway. They were fish much like this:

Such fish can be found in pet stores as "feeder fish"; live food for larger fish to eat. I kept good care of mine, changed their water often, but they didn't last long anyway. I was told "gold fish don't live very long." But it got me interested in keeping fish, and got me started with my first 10 gal. tropical fish aquarium.

Since then I've always been interested in aquarium fish. In the early 1990's, I tried keeping goldfish again, fancy goldfish, just three of them in a 15 gallon aquarium, with good filtration, etc. Despite my best efforts, they didn't last all that long either.

Many years later; I'm living on a small farm. We have a 300 gallon tub, it's made to hold drinking water for livestock, but we just use it to hold rainwater or creek water for watering green house plants.

During the summer, it becomes a breeding pool for mosquitoes. We usually add anti-mosquito biscuits to the water, but this past summer, we bought a bag of "feeder" goldfish instead, and dumped them in to eat the mosquito larvae.


The water got murky, so we used an old pump and set up a charcoal/ammonia stone filter up in an old cat liter bucket, with a roll of floss-like material in it.

It worked quite well. The water stayed clean and clear. We took buckets of water out to water the greenhouse plants, and occasionally replenished the tub with water from our creek. We fed the goldfish flaked food for goldfish. They got very tame and friendly. There are about 16 of them now.


We figured the goldfish would croak by the end of summer, but they haven't. In fact, they seem to be thriving and getting bigger.

So why haven't they died, like all the one's I've kept in aquariums? Well, it seems that by keeping them in a large filtered tub, and taking out part of the water and replenishing it on a regular basis, we were inadvertently providing the ideal conditions for keeping goldfish.

I've been reading up on goldfish, from many different websites. It seems that goldfish aquariums require frequent partial water changes, of 30% or so, every few weeks. Even if the water is filtered! This is because goldfish have no stomaches, only an intestine. Thus they produce a lot of waste and foul the water quickly. Filtration alone will not prevent buildup of certain toxins over time, requiring water changes.

I also found out that Goldfish DO live very long, 20+ years typically, 40+ years rarely, if cared for properly. The following site lists several points worth noting about the proper care of goldfish:

Goldfish (Carassius auratus)
[...] Goldfish should NEVER be kept in unfiltered bowl environments. This is not a suitable home for any living creature.

Fancy Goldfish need at least 75.7 Litres (20 US G.) per Goldfish and Common Goldfish need at least 208.2 Litres (55 US G.) per goldfish. If well cared for, Fancies can get around 20.3cm (8") long and Commons over 30.5cm (12"), so adequate room for swimming and turning is also necessary. For this reason, Commons do best in a pond environment.

* It is myth that Goldfish only grow to the size of their tank or that there are slow growing varieties.

Goldfish are large and messy fish, so you should have filters that move at least four times the amount of water in the tank per hour. Very high flow rates greater than seven times tank volume may be harmful as some varieties of Goldfish are weak swimmers. Filters with separate areas for mechanical and biological are best. [...]

I was shocked that they suggest 55 gal. PER FISH, for a common goldfish. But those little feeder fish are only small because they are babies. According to one video, they can grow quite large in just 3 years:



Yikes! The large one is a foot long! They are in a 75 gal. tank. Some sites I read said you only need 20 gal. for the first fish, and 10 gal. for each additional fish. But perhaps that's for the fancy ones, which also get big, but are still smaller than the plain ones.


So now I know why my "feeders" have lived; they got plenty of room, and regular water changes. But what's next? Am I going to have them for 20+ years?

Who knows? It's early days yet. They have yet to survive an Oregon winter outside (but I believe the pool is deep enough to allow them to survive the types of freezes we have). The cat, and local raccoons haven't discovered them yet; but it's a deep pool, so they could have a hard time accessing it.


What I DO know for sure is, that they have already lived longer than they would have if they were sold as fishfood for larger fish, as they were meant to be. So whatever length of life they have now is gravy. I will keep taking care of them, and enjoy them for however much longer they last.
