The fish, up close

More than a beautiful fish.

The Cobalt Dwarf Gourami, scientifically known as Trichogaster lalius, is a popular freshwater fish prized for its striking colouration and peaceful demeanor. This small gourami species displays vibrant hues of deep blue with hints of red and iridescent patterns that shimmer under aquarium lights. The males feature longer and pointed dorsal fins, while females have rounded ones. They have a labyrinth organ, allowing them to breathe atmospheric air and survive in oxygen-deprived waters. A peaceful and slow-moving fish, the Cobalt Dwarf Gourami is an ideal choice for community tanks.

Plan your setup

Behaviour

How it lives.

Cobalt Dwarf Gouramis are generally peaceful and can be kept in community tanks with other non-aggressive fish species. They may exhibit some territorial behaviour, especially during breeding. Males can be slightly aggressive towards each other, so it's best to keep only one male per tank unless in a spacious setup with plenty of hiding spots.

Tank planning

Set it up well.

Maintain a well-planted tank with floating vegetation to provide cover and simulate their natural habitat. Cobalt Dwarf Gouramis prefer slightly acidic to neutral water conditions with a temperature range of 24-28°C. Regular water changes are essential to keep water parameters stable and ensure the health of these delicate fish.
