Aquarium Care

The Dwarf Gourami thrives in a well-planted aquarium with gentle water flow and floating plants to diffuse intense lighting. Because they possess a labyrinth organ allowing them to breathe atmospheric air, keeping a lid on the aquarium and ensuring warm air above the water surface is essential.

Tank Mates

Trichogaster lalius is a calm fish that should not be kept with aggressive or fin-nipping species. Excellent tank mates include small tetras, rasboras, corydoras, and other peaceful community fish.
