White Cloud Mountain Minnow Care Guide Summary

The White Cloud Mountain Minnow, scientifically known as Tanichthys albonubes, belongs to the Cyprinids family group. Adults reach a maximum size of approximately 4 cm and have a fusiform body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the surface and mid-level zones of the aquarium and produces a low level of biological waste.

To thrive, the White Cloud Mountain Minnow requires a freshwater only aquarium with a minimum volume of 38 litres and a tank length of at least 45 cm. Water temperature should be maintained between 14°C and 22°C, with a pH range of 68 and a general hardness of 520 dGH. A moderate water flow is preferred.

The White Cloud Mountain Minnow is a rewarding species to keep, provided its core environmental needs are met. This species is available in 3 varieties: Standard, Golden, and Long Finned (Meteor Minnow). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

White Cloud Mountain Minnow Habitat Setup

When setting up an aquarium for the White Cloud Mountain Minnow, a moderate water flow best suits their natural preferences. Because this species occupies the surface and mid-level zones, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline and open swimming space in the centre of the tank for free movement. Useful additions include smooth gravel or rounded substrate to protect their sensitive barbels and dense planting to provide cover, break sightlines, and reduce stress. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.

White Cloud Mountain Minnow Compatibility Notes

Classified as peaceful, the White Cloud Mountain Minnow is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the surface and mid-level zones can help reduce competition and territorial overlap.

Cardinal Tetra

Paracheirodon axelrodi

Characins
4 cm Peaceful

A stunning schooling fish native to the upper Orinoco and Rio Negro basins in South America. Famous for its brilliant iridescent blue line and a vivid red stripe that extends the full length of its body (distinguishing it from the Neon Tetra). They are strictly schooling fish that thrive in warm, acidic blackwater environments.

Neon Tetra

Paracheirodon innesi

Characins
4 cm Peaceful

One of the most iconic freshwater fish in the hobby, famous for its striking iridescent blue and red stripes. Originally from the blackwater streams of the Amazon basin, they prefer slightly cooler water than many tropical fish and must be kept in schools to thrive, display natural behaviors, and feel secure.

Zebra Danio

Danio rerio

Cyprinids
5 cm Mostly Peaceful

One of the most robust and active aquarium fish available. Native to South Asia, they are a model organism in science due to their genetics. They are extremely active top-level swimmers that must be kept in schools to prevent stress and fin-nipping. They prefer cooler, oxygen-rich water with a current.

Bronze Corydoras

Corydoras aeneus

Catfish
7 cm Peaceful

A highly popular, peaceful schooling catfish known for its armor-like scales (scutes) and active bottom-feeding behavior. They are essential clean-up crew members but require a dedicated sinking diet (not just leftovers). Sand substrate is strictly required to prevent erosion and infection of their sensitive barbels. They are 'gut breathers' and will occasionally dart to the surface to gulp atmospheric air.

Rummy-Nose Tetra

Hemigrammus rhodostomus

Characins
5 cm Peaceful

Renowned as the tightest schooling fish in the freshwater hobby. They feature a bright red nose, a silver body, and a black-and-white checkered tail. They are excellent 'indicator fish'; their red noses will fade to pale pink if water quality drops or the fish are stressed. While there are three very similar species (H. rhodostomus, H. bleheri, P. georgiae) often sold under the same name, their care requirements are identical.

Dwarf Gourami

Trichogaster lalius

Anabantoids
7.5 cm Semi-Aggressive

A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
