Overview
What to know before you buy.
Often considered a red color morph or juvenile variation of Scatophagus argus, the Ruby Scat displays reddish hues, particularly on its fins and upper body. Care requirements are identical to the Green Scat, needing a large tank and a gradual transition from freshwater to a marine environment. A diet rich in plant matter is crucial for their health.

Everything you need to keep Ruby Scat healthy in a South African setup.
Water parameters
Keep pH 7.5–8.2 and 20–30°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.

Behaviour
Ruby Scat 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

Keeping brackish fish?
