About Blue Gourami

The Blue Gourami, also known as the Three Spot Gourami, is one of the larger and more robust gourami species available in the aquarium hobby. They feature a beautiful powder-blue coloration with two dark spots (the eye counts as the third spot). Native to Southeast Asia, these labyrinth fish can grow to 6 inches and are more active and somewhat more aggressive than smaller gourami species. They make excellent centerpieces for medium-sized community tanks but should not be kept with very small or long-finned fish.
