Expert Care Tips for Flowerhorn
- Large tank required: At 75+ gallons, Flowerhorn needs serious equipment investment. Ensure your filter is rated for at least 1.5× the tank volume.
- Warm-water species: Flowerhorn prefers 78–86°F. Use a reliable submersible heater with a thermostat — avoid temperature swings above 2°F per day.
- Adaptable pH range: Flowerhorn accepts pH 6.5–8.0. Most tap water falls within this range, but always test and acclimate slowly.
- Aggressive species: Flowerhorn will claim territory. Provide visual barriers (rocks, driftwood) and avoid housing with smaller or slow-swimming fish.
- Acclimation: Always drip-acclimate Flowerhorn over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
