Overview
What to know before you buy.
A stunning nano fish, the Ruby Tetra displays an intense, ruby-red coloration, especially in males. They are shy and do best in a dedicated species tank or with other very small, peaceful fish and shrimp. A heavily planted tank with soft, acidic water is required to see them at their best.

Care guide
Everything you need to keep Ruby Tetra healthy in a South African setup.
Water parameters
Keep pH 5–6.5 and 23–28°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.

Behaviour
Ruby Tetra is generally peaceful. Keep in a group where possible for natural behaviour.
Tankmates
Pair with similarly sized peaceful tankmates in freshwater fish. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Ruby Tetra vary by line and water chemistry — ask your local shop about proven pairs in SA.
Settling this fish in?
Condition the tap water, seed the filter, test through the first weeks — most early losses trace back to one of those.
