Expert Care Tips for Dwarf Gourami
- Mid-size tank: Dwarf Gourami needs 20+ gallons. Choose a tank at least 2× as long as the fish's adult size (3.5") for adequate swimming room.
- Warm-water species: Dwarf Gourami prefers 77–82°F. Use a reliable submersible heater with a thermostat — avoid temperature swings above 2°F per day.
- Narrow pH tolerance: Dwarf Gourami only tolerates pH 6.5–7.5. Test your tap water before buying — adjusting pH is harder than choosing the right fish for your water.
- Peaceful community fish: Dwarf Gourami works well in community tanks. Still, avoid housing with fish large enough to eat them — a 3.5" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Dwarf Gourami over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
