Behavior and Compatibility:
The Freshwater Flounder is a peaceful and solitary fish that spends most of its time on the substrate, where it camouflages itself to ambush prey. It is primarily nocturnal, becoming more active during the night. While generally not aggressive, it can prey on small fish and invertebrates, so tank mates should be chosen carefully.

Compatible Tank Mates:

Dietary Needs:
Freshwater Flounders are carnivorous and require a diet consisting of live or frozen foods such as bloodworms, brine shrimp, and small crustaceans. They may also accept high-quality sinking pellets designed for carnivorous fish. Feeding should be done in the evening or at night to match their nocturnal habits.

Breeding Tips:
Breeding Freshwater Flounders in captivity is rare and not well-documented. They spawn in brackish water conditions, laying eggs that develop into larvae before settling on the substrate. Providing optimal water conditions and a varied diet can support their health and potential breeding behavior.

Health and Maintenance:
Maintaining clean water and a stable environment is crucial for the health of Freshwater Flounders. Perform regular water changes of 25-30% weekly and monitor water parameters to prevent stress and disease.
