Gouramis

Dwarf Gouramis are beautiful small fish from Southeast Asia. Its preferred habitat is slow-moving waters, such as swamps, marshes, and rice paddies. In an aquarium setting, Gouramis are best when the tank is heavily planted with plenty of hiding spots.

Water conditions: Dwarf Gouramis are best kept in an aquarium with a neutral to slightly acidic pH of 6.5-7.5 and a water temperature of 24-28 degrees Celsius (75-82 degrees Fahrenheit). The water should be soft to medium hardness (3-10 dGH). This species can live in a tropical blackwater aquarium.

Compatibility

Consider the compatibility of the Gouramis with other aquarium inhabitants. Gouramis are relatively peaceful and can be kept with other small schooling fish, such as Tetras, rasboras, and livebearers like Guppies and Endler’s. However, they can become territorial if kept with larger fish, so it is best to research the fish you plan to keep in the aquarium to ensure compatibility.

Water Quality

One of the main issues with overpopulation in an aquarium is its effect on water quality. If too many fish are in the aquarium, the water quality will likely be poor. We can expect ammonia levels to be very high, adding undue stress to the fish. This can lead to other issues like dull coloration, lethargy, and diseases.

Observation

Observation is key. You must be aware whenever fish are not getting along or compatible. Keeping an eye on any changes can help you to identify and fix any potential problems before they become too severe.

With proper care and consideration for their needs, they can be kept in large groups, providing stunning color and activity to an aquarium.
