The natural habitat of the Opaline Gourami reveals much about its behavior and care needs. This small, colorful fish thrives in gentle environments with calm waters. Understanding where and how it lives helps hobbyists create the perfect tank conditions. The following sections explore its geographic range and preferred water conditions.
Geographic Range
Opaline Gouramis come from Southeast Asia. They live mainly in Thailand and Cambodia. These fish prefer slow-moving rivers and small streams. They also inhabit rice paddies and shallow ponds. These areas provide plenty of plants and hiding spots. The fish use these to avoid predators and find food.
Preferred Water Conditions
Opaline Gouramis enjoy warm water between 75°F and 82°F. The water should be soft to moderately hard. A pH level from 6.0 to 7.5 suits them best. They live in water with low flow, so strong currents stress them. Plenty of plants and floating leaves help mimic their natural home. Clear water and regular cleaning keep them healthy and active.
Tank Setup
Setting up the right tank for your Opaline Gourami is key to keeping it healthy and happy. This fish enjoys a calm environment with clean water and plenty of places to explore. The tank should mimic its natural habitat to reduce stress and encourage natural behavior.
Careful planning of tank size, water conditions, and decorations will create a perfect home. Each element plays a role in the well-being of your Opaline Gourami.
Tank Size Recommendations
Opaline Gouramis need space to swim comfortably. A tank of at least 20 gallons works well for one fish. For multiple gouramis, increase the size to 30 gallons or more. Bigger tanks help keep water stable and reduce stress.
Water Parameters
Maintain water temperature between 75°F and 82°F (24°C to 28°C). The pH level should be slightly acidic to neutral, around 6.0 to 7.5. Keep water hardness low to moderate, between 3 and 10 dGH. Regular water changes and good filtration keep water clean and safe.
Decor And Plants
Use soft plants and smooth decorations to avoid injuries. Floating plants help dim bright lights, creating a calm space. Include hiding spots like caves or driftwood for security. Open swimming areas balanced with plant cover suit their active nature.

Spawning Conditions
Opaline Gouramis prefer warm water between 78°F and 82°F. Keep the tank calm with minimal water flow. Provide plenty of plants or floating leaves for bubble nest building. Use soft, slightly acidic water for better results. Dim lighting encourages spawning behavior. Males build bubble nests at the water surface. They guard the nest and care for the eggs. Separate the female after spawning to prevent stress.
Caring For Fry
Once eggs hatch, fry need gentle care. Keep the tank clean and stable. Feed them tiny foods like infusoria or baby brine shrimp. Offer small meals several times a day. Avoid strong water currents to protect delicate fry. Gradually add fine flakes or crushed pellets as they grow. Watch for signs of stress or illness. Healthy fry grow quickly with proper care.

Signs Of Stress
Stress in Opaline Gouramis shows through behavior and appearance. They may hide more than usual or swim erratically. Loss of appetite is a common sign. Look for faded colors or clamped fins. Rapid breathing or gasping at the surface also indicates stress. Watch for white spots or patches on the body. These signs suggest illness or poor water conditions.
Preventive Care
Good tank maintenance prevents many health problems. Keep water clean by regular changes and proper filtration. Maintain stable water temperature around 75-82°F. Avoid overcrowding to reduce stress and disease spread. Feed a balanced diet with quality flakes or pellets. Adding live or frozen foods boosts nutrition.
