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.
Key traits
Care guide
Keeping Freshwater Flounder healthy in a South African setup.
Tank setup
Size the aquarium to Freshwater Flounder's adult size and activity level. Provide hiding spots and stable, well-filtered water; it suits a community setup.
Water parameters
Keep pH 7–8.5 and 22–28°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Carnivore. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful. Watch it at feeding time and at lights-out to see its real temperament in your tank.
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 Freshwater Flounder depends on the line and water chemistry; ask your shop about proven pairs.
