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.
Key traits
Care guide
Keeping Mono Argentus healthy in a South African setup.
Tank setup
Size the aquarium to Mono Argentus's adult size and activity level. Provide hiding spots and stable, well-filtered water; it suits a community 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.
Feeding
Omnivore. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful. Keep it in a group for natural behaviour.
Tankmates
Choose tankmates of similar size and temperament with the same water needs. Avoid fin-nippers and anything large enough to eat it.
Breeding
Breeding success with Mono Argentus depends on the line and water chemistry; ask your shop about proven pairs.
