10 × White Cloud Mountain Minnows (Tanichthys albonubes)

This listing is for a group of 10 White Cloud Mountain Minnows (Tanichthys albonubes, 2.5-3 cm), supplied together.

White Clouds are hardy, peaceful shoalers that thrive in groups: kept ten together they stay bolder, display more and suit mature, cooler aquariums kept within their temperature range.

If you want a lively shoal that looks elegant without demanding tropical heat, the White Cloud Mountain Minnow is a good choice for a cooler community tank. Known scientifically as Tanichthys albonubes, these small cyprinids are famous for their bright lateral stripe, red-tipped fins, peaceful nature, and unusual ability to thrive in cooler aquariums. They are better suited to a cooler community setup than a permanently warm tropical tank, whether you are new to fishkeeping or planning a planted shoal.

This guide covers tank size, diet, behaviour, compatible tank mates, breeding and health. Adults typically reach 3-4 cm, live around 3-5 years, and do best in groups of 6 or more. Their easy-going temperament, low aggression, and shimmering colours make them a favourite community tropical fish UK option for planted aquariums. A mature planted aquarium gives this shoal space to show its natural movement and colour. If you want active, social fish that enhance aquarium aesthetics and foster a true community feel, this is one of the best beginner-friendly fish you can buy.

Where Do White Cloud Mountain Minnows Come From? Natural Habitat Explained

The White Cloud Mountain Minnow habitat is rooted in East Asia, specifically China’s Guangdong province. In the wild, Tanichthys albonubes was associated with cool hill streams and slow-moving waters near the White Cloud Mountain region, which gave the species its common name. These waters are usually clear, well-oxygenated, and shaded by surrounding vegetation, with a mix of pebbles, leaf litter, and aquatic plants.

That natural setting explains why this fish does so well in a planted aquarium with gentle current and stable conditions. Unlike many fish sold under the tropical fish UK banner, White Clouds are not heat-loving equatorial fish. They can do well in a cooler indoor aquarium kept within their recommended range. Their wild diet includes tiny insects, zooplankton, micro-crustaceans, and plant matter, which is why a varied omnivore diet works so well in captivity.

White Clouds are native to East Asia, not the UK. In a home aquarium, their temperature needs matter more than the broad 'tropical fish' label: check the actual water temperature rather than assuming a heated tank is suitable.

How to Set Up the Perfect Tank for White Cloud Mountain Minnows

White Clouds have straightforward but specific setup needs. A proper White Cloud Mountain Minnow tank setup starts with space for group behaviour. For this group of ten, choose an aquarium of at least 60 litres with a base around 60 × 30 cm or larger. That extra length gives the shoal room to move together, display, and establish a relaxed rhythm.

Tank Size Requirements

The right White Cloud Mountain Minnow tank size depends on group size. For this shoal, allow at least 60 litres for the ten fish sold here, with room for their active shoaling and stable water quality. This also answers the common beginner question, what is a good size fish tank for a beginner: for this species, 60 litres is easier to maintain than a tiny nano tank. Small tanks fluctuate faster, especially with temperature and waste.

Water Parameters

The ideal White Cloud Mountain Minnow water parameters are straightforward. Aim for a White Cloud Mountain Minnow water temperature of 18°C, within their 14-22°C range. Sustained warmer conditions may shorten their lifespan, so choose tank mates that also suit cooler water. Check that any companion species also thrives in this cooler range. Their White Cloud Mountain Minnow pH level should stay between 6.0 and 8.0, with a neutral 7.0 being ideal. White Cloud Mountain Minnow water hardness can range from 5-20 dGH, making them adaptable to many UK water supplies.

Filtration and Flow

White Cloud Mountain Minnow filtration needs are moderate. They appreciate clean, oxygen-rich water and a gentle to moderate current. A sponge filter or small internal filter works well, especially in smaller aquariums. For most aquariums, White Clouds should not be kept in an unfiltered tank unless it is a heavily planted, mature, expertly maintained setup. For most aquarists, filtration is essential for stable ammonia control and oxygenation.

When planning your White Cloud Mountain Minnow aquarium setup, pair them with a reliable filter and avoid oversized units that blast them around. For a cool-water community aquarium, focus on filtration that turns the tank over gently rather than aggressively.

Substrate, Plants, and Decor

A dark sand or fine gravel substrate makes their colours stand out. Smooth pebbles, driftwood, and dense planting around the edges help them feel secure while leaving open swimming space in the middle. White Clouds suit planted aquariums well. Good plant choices include Java moss, hornwort, water sprite, and anubias. Fine-leaved plants are especially useful because this species is an easy egg scatterer.

Although White Clouds do not need a heater in most homes, always check actual room temperature. If winter drops your aquarium below the safe range, a low-set heater may still be useful. They are cool-water fish, not ice-water fish.

What Do White Cloud Mountain Minnows Eat? Complete Feeding Guide

The White Cloud Mountain Minnow diet is omnivorous, which means they eat both animal protein and plant-based material. In nature, they pick at tiny invertebrates and suspended food items. In the aquarium, they do best with a varied menu built around quality micro flakes, crushed pellets, frozen foods, and occasional live foods. Choose foods sized for their small mouths rather than standard large flakes.

Staple Foods

A good White Cloud Mountain Minnow feeding guide starts with a fine flake or mini pellet. Use a quality fine flake or mini pellet that can be portioned easily; vary it with suitable frozen or live foods.

Supplemental Foods

For extra condition and better breeding response, offer daphnia, baby brine shrimp, cyclops, and finely chopped bloodworm. These can be frozen or live. Live daphnia or newly hatched brine shrimp can encourage natural feeding behaviour. White Clouds are not a substitute for aquarium maintenance or snail control.

Feeding Frequency and Portion Control

For White Clouds, feed once or twice daily in small portions they finish within 30-60 seconds. That is the safest answer to common care questions in a mixed community. If you are away, an automatic tropical fish feeder uk can work for dry foods, but test it before relying on it.

Another frequent question is how long can small tropical fish go without food. Healthy adult White Clouds can usually manage several days, but regular fasting should not be part of routine care. Consistency supports immune function, colour, and breeding condition.

Time	Food	Amount
Morning	Fine flake or mini pellets	Small pinch, fully eaten in under 1 minute
Evening	Frozen daphnia or baby brine shrimp	Very small portion

White Cloud Mountain Minnow Appearance: Colors, Patterns & Varieties

The classic white cloud fish has a slim, torpedo-shaped body reaching a White Cloud Mountain Minnow size of around 3-4 cm. The most striking feature is the luminous gold-to-silver stripe running from the eye toward the tail, often set against an olive-brown or bronze body. The fins show flashes of red, orange, and white, especially when the fish are settled and well fed.

In a mature shoal, the overall effect is subtle but beautiful. This is not a bulky show fish; it is a schooling species whose beauty comes from movement, contrast, and group behaviour. Strong plant cover and darker substrate help intensify colour, especially in a White Cloud Mountain Minnow in planted tank display. Their White Cloud Mountain Minnow lifespan of 3-5 years also means you can enjoy that display for a good length of time with proper care.

Sexing them is fairly easy once mature. In White Cloud Mountain Minnow male vs female comparisons, males are usually slimmer, more colourful, and more active in display. Females are fuller-bodied, especially when carrying eggs. During breeding, males may spar and display to rivals; watch the group rather than assuming the ten supplied fish contain a particular sex ratio.

Good diet, stable water and a suitable group size help White Clouds show their natural colour.

What Fish Can Live With White Cloud Mountain Minnows? Compatibility Guide

One reason White Clouds are often called the best minnow for community tank setups is their calm, social nature. The right White Cloud Mountain Minnow tank mates are other peaceful fish that enjoy similar temperatures and do not outcompete or intimidate them. If you are building a cool-water or temperate community tropical fish UK aquarium, this species is one of the safest starting points.

Ideal Tank Mates

The best White Cloud Mountain Minnow compatible fish include other White Clouds, small danios, peaceful corydoras in suitable temperatures, and some small barbs that tolerate cooler water. White Clouds shine when kept in a group of their own first, then combined with carefully chosen companions. Choose companions with similarly calm behaviour and compatible cooler temperature needs.

For browsing related species, you may also like the colourful Albino Sky Blue Guppy or Red Black Guppy, though guppies generally prefer warmer water than White Clouds. That makes them more of a comparison species than an ideal long-term match. If your goal is a cool-water shoal, another group of White Cloud Mountain Minnows Aquarium is usually the best addition.

Species to Avoid

For White Clouds, avoid large cichlids, predatory fish, fin-nippers, and any species that need much warmer water. That includes fish such as the Gold Giant Gourami, Piaractus Brachypomus - Red-Bellied Pacu -, Red-Bellied Pacu - Piaractus Brachypomus, and Polypterus Endlicherii. These are unsuitable because of size, feeding behaviour, or predatory instinct. White Clouds should never be treated as feeder fish for larger species.

Community Stocking Examples

A 60-litre aquarium can hold 8-10 White Clouds as a single-species shoal. In a larger 90-litre setup, you might keep 10-12 White Clouds with a small bottom group of cool-tolerant corydoras if temperatures are chosen carefully. Check each companion's adult size, temperament and temperature needs before stocking.

Invertebrates

White Clouds are generally safe with adult shrimp and snails, though very small shrimplets may be eaten. They are not specialist snail hunters, and should not be chosen for snail control. Their small mouths limit serious predation.

Species	Compatible?	Notes
White Cloud Mountain Minnows Aquarium	✅ Yes	Best kept in larger groups of their own kind for natural shoaling
Albino Sky Blue Guppy	⚠️ Caution	Peaceful, but guppies usually prefer warmer water
Gold Giant Gourami	❌ Avoid	Too large and unsuitable in both size and conditions

Compatibility depends on temperature as well as temperament. Peaceful warm-water fish are still poor matches if they need 25°C or above. White Clouds do best with species chosen around their cooler range.

How to Breed White Cloud Mountain Minnows: Complete Breeding Guide

White Cloud Mountain Minnow breeding is one of the easiest fish breeding projects for beginners. They are egg scatterers and often spawn in a mature planted aquarium without much intervention. Dense planting or a separate breeding tank can improve fry survival.

Breeding Setup

A separate 20-30 litre breeding tank works well, though spawning can happen in the main aquarium too. Use cool, clean water around 18-20°C, gentle filtration, and plenty of fine-leaved plants or spawning mops. This is the ideal White Cloud Mountain Minnow aquarium setup for fry survival because adults may eat some eggs.

Male vs Female

In mature fish, males are slimmer and more intensely coloured, while females are rounder through the belly. Condition both sexes with varied foods for 1-2 weeks before breeding. Good frozen and live foods help trigger spawning.

Spawning Behaviour and Egg Care

Males display to females and may spar lightly with each other. Eggs are scattered among plants and usually hatch in 36-48 hours depending on temperature. Adults do not provide parental care, so remove them or move the eggs if you want maximum fry survival. A separate breeding setup helps protect eggs and fry.

Fry Care

Newly hatched fry need infusoria, liquid fry food, or very fine powdered food at first, followed by baby brine shrimp as they grow. Frequent small water changes are safer than large ones. Growth is steady, and young fish start to show their stripe and fin colour within a few weeks.

White Cloud Mountain Minnows vs Similar Species: Which Should You Choose?

Comparison matters because many small shoaling fish look similar on a shop list but behave very differently in the home aquarium. Compare their cooler water needs with those of warmer species such as neon tetras and endlers. The biggest difference is temperature preference.

Feature	White Cloud Mountain Minnow	Neon Tetra
Max Size	4 cm	4 cm
Care Level	Beginner	Beginner to moderate
Temperature	14-22°C	22-26°C
Best For	Cool-water community tanks	Warmer planted tropical tanks

Feature	White Cloud Mountain Minnow	Endler Guppy
Temperament	Peaceful shoaler	Peaceful livebearer
Breeding	Egg scatterer	Livebearer
Temperature	Cooler water	Warmer water
Best Display	Active schooling group	Colourful mixed-sex colony
Best For	Low-heat setups	Heated community tanks

Choose White Clouds if you want a peaceful shoal in a cooler aquarium, especially if you are new to fishkeeping or want to avoid high tropical temperatures. Choose neon tetras or endlers if you are building a warmer tropical setup. If you are browsing similar fish, compare them carefully rather than assuming all small schooling fish need the same care.

Common Health Problems in White Cloud Mountain Minnows & How to Prevent Them

Strong White Cloud Mountain Minnow health starts with clean, cool, stable water. Healthy fish swim actively in the mid to upper levels, hold fins open, feed eagerly, and shoal naturally. Their stripe should look clear and bright, and the body should be slim but not pinched.

Common Problems

The main White Cloud Mountain Minnow diseases seen in captivity are stress-related issues such as ich, fin damage from poor tank mates, and bacterial infections linked to bad water quality. Because they are often sold as hardy beginner fish, some people underestimate the importance of cycling and quarantine. Sudden heating, overcrowding, or mixing them with unsuitable species is a common trigger for illness.

Prevention

The best White Cloud Mountain Minnow ideal conditions are simple: stable temperature, good oxygenation, regular water changes, varied diet, and a proper group size. Maintain the correct White Cloud Mountain Minnow pH level, keep hardness within range, and avoid warm-water tank mates. If you are using an online aquarium fish calculator uk, remember that behaviour and temperature matter as much as litres-per-fish estimates.

Ask the seller about arrival and acclimation guidance, and make sure the receiving aquarium is ready before the fish arrive.

Understanding White Cloud Mountain Minnow Behavior in the Aquarium

The natural White Cloud Mountain Minnow behaviour is active, social, and non-aggressive. They are a shoaling species that spends much of the day cruising the middle and upper levels of the tank. In a proper group, they move with confidence and often perform short bursts of synchronized swimming.

This species is not shy once settled. Males may posture and display to one another, especially in breeding condition, but serious fighting is rare. That makes them excellent White Cloud Mountain Minnow for beginners and a strong answer to the question of the best minnow for community tank use. If kept in too small a group, they can become nervous and washed out, so always prioritise numbers over buying a random mix of species.

To encourage natural behaviour, provide open swimming lanes, plant cover at the edges, and a group of at least 6-8 fish. Their social confidence is one of the biggest reasons they remain popular in UK aquariums.
