Ideal Water Parameters for Flowerhorn Fish
1. Water Temperature
Flowerhorn fish prefer warm water.
Ideal temperature: 26°C – 30°C
Using a reliable aquarium heater helps maintain stable temperature, especially during seasonal changes.
2. pH Level
Flowerhorns generally prefer slightly alkaline water.
