Overview
What to know before you buy.
Also known as the Silver Moony, this active, shoaling fish has a beautiful silver, disc-shaped body. Like other monos, they are best kept in groups and require a transition from low-brackish to high-salinity water as they mature. A large tank with ample swimming space is essential to accommodate their active nature.

Care guide
Everything you need to keep Mono Argentus healthy in a South African setup.
Water parameters
Keep pH 7.5–8.5 and 24–28°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.

Behaviour
Mono Argentus is generally peaceful. Keep in a group where possible for natural behaviour.
Tankmates
Pair with similarly sized peaceful tankmates in brackish fish. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Mono Argentus vary by line and water chemistry — ask your local shop about proven pairs in SA.
Keeping brackish fish?
Shifting salinity stresses fish slowly — condition, measure, and change water gradually.
