Flowerhorns are stunning and fascinating fish with a devoted following among aquarists. Known for their vibrant colors, unique appearance, and engaging personalities, Flowerhorns can make rewarding pets for those willing to provide the specialized care they require.

General Info:

Scientific Name: Hybrid Cichlid (result of crossbreeding various cichlid species) Size: 10-12 inches, some can grow larger Lifespan: 8-10 years Minimum Tank Size: 75 gallons

Distribution & Habitat:

Flowerhorns are man-made hybrid fish, and therefore, do not have a natural distribution or habitat. They were first developed in the late 1990s in Malaysia and Thailand through selective crossbreeding of various cichlid species from Central and South America.


Flowerhorns are large, colorful fish with a distinctive hump or "nuchal" hump on their foreheads. Their vibrant colors and intricate patterns make them highly sought after by aquarium enthusiasts. Males are generally more colorful and have more prominent humps than females.

Aquarium Setup:

  • Provide a large tank with at least 75 gallons of water capacity.

  • Maintain a water temperature between 80-86°F (27-30°C).

  • Keep the pH between 6.0 and 8.0.

  • Include a powerful filtration system to handle the significant waste produced by these large fish.

  • Provide hiding spots and decorations, but ensure there's plenty of open swimming space.

  • Use a heater to maintain stable water temperature.

Diet and Feeding:

  • Offer a high-quality, protein-rich pellet food as their staple diet.

  • Supplement their diet with frozen or live foods like brine shrimp, bloodworms, and krill.

  • Offer occasional treats of feeder insects, such as mealworms, crickets, or roaches.

  • Feed 2-3 times a day in small, manageable portions to prevent overfeeding.

Breeding and Reproduction:

  • Flowerhorns are not easily bred due to their hybrid nature and aggression.

  • If attempting to breed, provide a separate breeding tank and introduce the female slowly to the male's territory.

  • Use a tank divider to prevent injury during the initial introduction.

Health and Disease Prevention:

  • Maintain clean water and stable water parameters.

  • Provide a varied and balanced diet to prevent nutritional deficiencies.

  • Quarantine new fish before introducing them to the main tank.

  • Watch for signs of illness, such as changes in behavior, appetite, or appearance.

Social Structure and Tank Mates:

  • Flowerhorns are aggressive and territorial, making them generally unsuitable for community tanks.

  • They are best kept as the only fish in the tank or with a single, compatible mate.

  • If housing with other fish, monitor for signs of aggression and separate if necessary.

  • Insects like mealworms, crickets, and roaches can be offered as occasional treats.

  • Ensure insects are gut-loaded before feeding to provide maximum nutritional value.

  • Feed appropriately-sized insects to prevent choking hazards.

Variety is key:

Flowerhorn fish require a balanced and varied diet to stay healthy and thrive. While insects can be a valuable source of protein, they should not be the only food in your Flowerhorn fish's diet. Make sure to offer a variety of foods, such as fish pellets, shrimp, and vegetables, to ensure a well-rounded diet.

Choose the right insects:

Not all insects are suitable for Flowerhorn fish to eat. Stick to feeder insects such as mealworms, superworms, crickets, and brine shrimp, which are safe and nutritious for Flowerhorn fish to consume. Avoid feeding wild-caught insects, as they may carry harmful bacteria or parasites.

Feed in moderation:

While insects can provide valuable nutrients, they should be fed in moderation. Overfeeding insects can lead to health problems such as obesity and digestive issues. As a general guideline, offer insects to your Flowerhorn fish once or twice a week, and adjust the amount based on their appetite and activity level.

Observe feeding behavior:

When feeding insects to your Flowerhorn fish, monitor their behavior closely to ensure they are not overeating or choking on their food. Remove any uneaten insects after a few minutes to prevent them from fouling the water.

Hydrate dried insects:

If you choose to feed your Flowerhorn fish dried insects, make sure to rehydrate them before feeding. Soak the insects in water for at least 10-15 minutes to soften them and make them easier to digest.

Gut-load insects:

To maximize the nutritional value of feeder insects, consider gut-loading them with nutritious foods such as leafy greens or fish food before feeding them to your Flowerhorn fish.

Prepare insects correctly:

Depending on the type of insect, you may need to crush, chop, or gut-load them before feeding to your Flowerhorn fish. Always follow the instructions on the package or consult with a fish expert to ensure you are preparing the insects correctly.

Offer a variety of insects:

Flowerhorn fish can benefit from a variety of insects in their diet. You can offer mealworms, superworms, crickets, and brine shrimp as part of their diet. Rotate the insects you feed to provide a variety of nutrients.

Avoid overfeeding:

It can be tempting to feed your Flowerhorn fish large amounts of insects, but this can lead to health problems. Always offer insects in moderation and balance them with other appropriate foods to ensure a well-rounded diet.

Consult with an expert:

If you have any questions or concerns about feeding insects to your Flowerhorn fish, always consult with a veterinarian or fish expert for guidance and advice.
