Opaline Gourami by LiveAquaria
The Opaline Gourami is also known as the Marbled Gourami and is a color variation of the Blue Gourami. This gourami is a rather peaceful fish that is very comical to watch as a juvenile. The Opaline Gourami is silvery pale blue with darker blue markings. Opaline Gouramis are considered Labyrinth Fish, meaning they breathe directly from the air and must have access to the surface of the tank.
The Opaline Gourami is compatible with a variety of tank mates that are of similar size and temperament. While males can be territorial with each other, they become timid around more aggressive fish. The ideal tank setup would be a minimum of 20 gallons with plenty of live plants, rocks, and driftwood for hiding places.

The Opaline Gourami is a charming addition to my 20-gallon tank. It’s peaceful and active, especially when young. I love how it moves through the plants and driftwood. It’s easy to care for as long as the surface is accessible for air breathing.

Great fish for a community tank. I paired it with some peaceful tetras and shrimp. The fish seems happy and stays calm. Just make sure the tank has plenty of hiding spots and a surface for air access.

The coloration is beautiful – a soft blue with marbled patterns. It’s not aggressive and blends well with live plants. I’ve had it for three months and it’s thriving. Highly recommend for beginner aquarists.
