Overview
What to know before you buy.
Often called a Hogchoker, this fascinating flatfish is a master of camouflage, blending perfectly with a sandy substrate. While young specimens can tolerate freshwater, they require low-end brackish conditions for long-term health. They are peaceful but shy bottom-dwellers that need a diet of sinking carnivorous foods like bloodworms and brine shrimp.

Care guide
Everything you need to keep Freshwater Flounder healthy in a South African setup.
Water parameters
Keep pH 7–8.5 and 22–28°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.

Freshwater Flounder is an omnivore. Feed a varied diet appropriate for brackish fish — quality flakes, pellets, or frozen foods sized to the mouth.
Behaviour
Freshwater Flounder is generally peaceful. Observe during feeding and at lights-out for true temperament.
Tankmates
Pair with similarly sized peaceful tankmates in brackish fish. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Freshwater Flounder 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.
