The Paradise Blue Gourami is a stunning freshwater fish prized for its iridescent blue body, flowing fins, and bold personality. As one of the first tropical fish ever kept in home aquariums, it’s both a classic and a standout in any tank. With vibrant coloration and a labyrinth organ allowing it to breathe air, this species adapts well to a wide range of setups.

Temperament & Tank Mates:
Males can be territorial—especially during breeding—but they do well in larger tanks with space to establish territories. Keep with robust, non-aggressive tankmates. Avoid fin-nipping species or other brightly colored, long-finned males to prevent conflict.

Fun Facts:

• Paradise Gouramis can breathe atmospheric air thanks to their labyrinth organ—so they can survive in low-oxygen water.

• These fish were among the first tropical species introduced to the aquarium hobby in the 1800s.

• Their color intensity often deepens during displays or territorial interactions.

Diet:
Omnivorous – enjoys a varied diet of high-quality flakes, pellets, frozen foods (brine shrimp, bloodworms), and occasional plant matter.

Tank Setup Tips:
Provide plenty of plants, floating cover, and gentle filtration. Males appreciate visual barriers (like driftwood or tall plants) to reduce territorial stress.

Add a splash of old-school elegance and vibrant attitude to your tank with the Paradise Blue Gourami—a timeless beauty with personality to match.
