A classic choice for beginner aquarists, the White Cloud Mountain Minnow is small, peaceful, and surprisingly beautiful. With its shimmering silver-green body, bright red fins, and iridescent stripe, this cold-tolerant schooling fish thrives in both unheated aquariums and outdoor ponds. It’s active, easy to care for, and brings gentle movement and charm to any setup.

Aquarium Setup:
Ideal for tanks of 30 litres or more, these fish prefer cool, well-oxygenated water with a gentle flow.

White Clouds are hardy, adaptable, and undemanding. They live 3–5 years and are well-suited to room-temperature tanks without heaters. Breeding is easy and often occurs naturally in well-maintained aquariums with plants or spawning mops.
Care Tips:
✔ No heater required – perfect for cool water tanks
✔ Keep in groups for confidence and colour display
✔ Provide gentle filtration and surface agitation
✔ Feed a varied diet to maintain health and colour
✔ Great for low-tech or nano aquariums
Compatibility:
An excellent choice for peaceful community tanks with small fish like guppies, danios, Corydoras, shrimp, and snails. Avoid aggressive or heat-loving species that may outcompete them or require incompatible conditions.
Availability:
Widely available in the Australian aquarium trade, including longfin, golden, and albino varieties. Commonly sold in small groups—ideal for beginners and cool-water setups.
Disclaimer:
White Cloud Minnows are social fish that thrive in schools. Always keep six or more together to promote natural behaviour and wellbeing.
