Opaline Gourami

The Opaline Gourami combines a blue-silver body with irregular darker marbling. This patterned form of the three-spot gourami makes a striking addition to a roomy planted aquarium. Each fish develops its own pattern, so markings will differ from the reference photo.

Fish details

• Scientific name: Trichopodus trichopterus
• Size offered: Approximately 4–5 cm
• Adult size: Up to about 15 cm
• Origin: Southeast Asia; Opaline is a cultivated color form
• Water type: Freshwater
• Temperament: Can become territorial, especially mature males

Recommended aquarium conditions

• Aquarium: 30 US gallons or larger; allow more space for a community or multiple gouramis
• Temperature: 24–28°C (75–82°F)
• pH: 6.0–8.0

Combine tall plants and sheltered corners with an open swimming area. Maintain filtration without a strong current across the entire tank. Keep a secure lid and leave access to air at the surface. These gouramis breathe air at the surface, so floating plants should not cover it completely.

Diet and feeding

Feed quality omnivore flakes or pellets, varying the menu with small frozen foods and some vegetable-based food. Serve only a small amount at each feeding.

Compatibility and care

Select similar-sized, confident community fish that do not nip fins. Temperament varies, and some adults bully timid tankmates. Separate fish if chasing becomes persistent; males can be particularly defensive around a bubble nest.

Plan the aquarium for its adult size rather than its purchase size. Stable water conditions and regular partial water changes support long-term care.
