Expert Care Tips for Pearl Gourami
- Mid-size tank: Pearl Gourami needs 20+ gallons. Choose a tank at least 2× as long as the fish's adult size (4.5") for adequate swimming room.
- Warm-water species: Pearl Gourami prefers 75–82°F. Use a reliable submersible heater with a thermostat — avoid temperature swings above 2°F per day.
- Adaptable pH range: Pearl Gourami accepts pH 6.0–7.5. Most tap water falls within this range, but always test and acclimate slowly.
- Peaceful community fish: Pearl Gourami works well in community tanks. Still, avoid housing with fish large enough to eat them — a 4.5" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Pearl Gourami over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
