What sort of water does a gourami need?

* Temperature: Gouramis are tropical fish and prefer water temperatures between 75-86°F (24-30°C).

* pH: Gouramis prefer slightly acidic water with a pH between 6.0-7.0.

* Hardness: Gouramis can tolerate a wide range of water hardness, but they prefer soft to moderately hard water with a dGH of 5-15.

* Chlorine and Chloramine: Gouramis are sensitive to chlorine and chloramine, which are chemicals commonly used to disinfect tap water. It is important to use a water conditioner to remove these chemicals before adding gouramis to your aquarium.

* Ammonia and Nitrite: Gouramis are also sensitive to ammonia and nitrite, which are toxic waste products that can build up in aquariums. It is important to regularly test your aquarium water and perform water changes as needed to keep these levels low.
