What type of water and temperature is best for Flower Horns?
Flower Horns do well in all types of clean water. This fish is very hardy, and can endure water conditions that are not suitable for most breeds of aquarium fish. This is also part of the reason why the Flower Horn is well received by many tropical fish hobbyists. But the ideal pH level in the water should be around pH 7 to 7.8, with water temperature ranging between 27 °C to 32°C. For temperate/colder climate regions, just use a conventional water heater.
