Chocolate gouramis can be sensitive to water conditions. Their native habitats are peat swamps and black water streams. Such habitats have very low mineral content which results in an extremely low pH, sometimes even below 4.0. The water is very soft and usually dark from decayed organic material.
Ideally, the chocolate gourami habitat should be well planted with live plants, including floating plants to maintain partial light. The water should be conditioned with peat extract, or filtered through peat. Filtration should not produce strong currents within the tank, so a sponge filter is ideal for this species.
Water should be changed often, but only in small amounts (10 percent or less) to avoid major changes in water chemistry.
