Flower Horn Fish Care Guide
The Flower Horn Fish (also known as Hua Luo Han) is a stunning hybrid from the Cichlid family, originally bred in Southeast Asia. Recognized for its vivid colors, prominent nuchal hump (forehead bump), and bold black markings (often resembling Chinese characters), this unique fish has gained worldwide popularity among aquarium hobbyists.
1. Origin and Temperament
- Family: Cichlidae (genus Cichlasoma)
- Hybrid of: Trimaculatus, Festae, and Blood Parrot species
- Behavior: Highly territorial and aggressive
- Tankmates: Best kept alone or with a secure tank divider
2. Tank Setup & Water Conditions
🔹 Temperature
- Ideal range: 28–31°C (82–88°F)
🔹 pH Level
- Preferred pH: 7.5 – 8.0 (slightly alkaline)
- Add crushed coral to substrate for better pH stability
- Avoid sudden pH changes; test regularly
🔹 Filtration
Choose a high-quality filter that includes:
- Efficient mechanical filtration (for debris)
- Strong biological filtration (for ammonia & nitrite control)
- Easy maintenance access
🔹 Water Changes
- Change 30–50% of the tank water once a week
- Topping up evaporated water is not enough
- Clean water supports healthy growth and vibrant color
🔹 Water Flow
Proper circulation helps:
- Even out temperature throughout the tank
- Distribute oxygen efficiently
- Prevent surface film that blocks gas exchange
🔹 Aquarium Salt (Optional)
- Acts as a mild antiseptic
- Provides essential sodium and chloride ions
- Helps reduce stress and prevent certain parasites
3. Feeding Guidelines
- Very good appetite; eats pellets or live food
- Feed small portions multiple times a day
- Combine high-quality pellets with occasional live treats
- Use color-enhancing food in moderation to avoid chemical buildup
4. Tank Environment
- Use a thin layer of gravel and keep decor simple
- Avoid overcrowding—space helps reduce stress
- A stressed Flower Horn may lose its colors, nuchal hump, or stop growing
The Flower Horn Fish is an eye-catching, interactive pet that’s relatively easy to maintain. Its aggressive nature means it’s best kept alone, but with proper care—clean water, a balanced diet, and a stress-free environment—it will thrive and display its full beauty.
