Flowerhorn Genetics

A hybrid fish called a Flowerhorn is built on the blood parrot, one of the first hybrid fish created by humans. Since the original Flowerhorn cichlids, also known as luohans, several other cichlids have been crossed with the Flowerhorn. Its genetic heritage is unclear and differs widely depending on the plant species. Nevertheless, it doesn’t typically get ill and is lovely overall.

Additionally, the “Flowerhorn Kok” gene is the one that regulates Kok’s growth. The nuchal hump, which would be the projection on the skull of Flowerhorns, is created by this trait. This gene controls the Kok’s size and coloring. 

Genes for Flowerhorn Kok can be either dominant or recessive. This gene’s dominant version results in a bigger, brighter Kok, whereas its negative form results in a shorter, blander Kok. 

The maturity of the fish has an impact on the Kok’s size as well. Flowerhorns often have little Koks when they are young. Normally, their Koks will enlarge as they mature.

How to Maximize Head Growth

Giving your Flowerhorn high-quality meals is one of the best strategies to increase the size of its head. It will enable them to enlarge their nuchal protrusion. Live meals, frozen meals, and pellets are a few excellent alternatives.

Attempt mirrored time, when a fish mistakenly believes that it is another fish when it sees its reflection on the glass. They become more territorial, which can make them more aggressive. Although there are no pieces of evidence to back this up, many individuals think it promotes head development.


Although Flowerhorns are not fussy eaters, they need a diet rich in proteins and very diversified. They won’t have any issues eating dry and frozen meals. 

Therefore living goods are not required. In addition to supplements like sun-dried crickets, grasshoppers, mealworms, anchovies, and frozen shrimp, Flowerhorns require a staple pellet that contains vitamins and minerals.

You may also feed Flowerhorns like white, black, earthworms, and nightcrawlers. To avoid excessive ammonia, nitrite, and nitrate, give your pet multiple smaller meals throughout the day. 

The quantity that owners must give to Flowerhorns varies according to the type of food and Flowerhorn species being eaten and is normally fed three times daily. Generally speaking, while feeding Flowerhorns, only give them as much as they can consume in 20 to 40 seconds.

Since most Flowerhorn cichlids are omnivores, maintaining them and selecting the proper food is simple. So, you should provide and pick a nutritious diet for them.

Water Conditions

The fish never reproduced in the ocean because Flowerhorns are descended from a diverse group of cichlids, most of which have distinct water needs. They prefer water that is mild to slightly hard. 

However, steadiness is more crucial than “ideal” water characteristics. Basic recommendations for Flowerhorn water temperature are as follows:

  • the pH level of  6.0-8.0
  • 80-85 degrees Fahrenheit
  • 6° to 20° dGH in Alkalinity

Compared to other fish, Flowerhorns are more susceptible to ammonium, nitrite, and nitrates. Rotating the tank prior is essential since any detectable level of ammonia or nitrite can harm your fish.

Nitrates are produced towards the cycle’s conclusion, whereas ammonia and nitrite only arise. Individuals often become unaware of nitrates, particularly those who maintain fish like Flowerhorns that create a lot of waste. 

Even though your water seems completely clean, you should still perform those twice-weekly water changes since nitrates are invisible poisons.


The parrot and mirror methods use the same idea. These methods irritate the Flowerhorn to raise the nuchal hump, change its color, and boost its activity.

Some people dislike the parrot method because the parrot fish will likely injure your Flowerhorn.

On the other hand, get a mirror with no jagged corners and put it inside the tank for 15 minutes daily for at least one to three months. Make sure the mirror is positioned within the tank and not on the outside.

A mirror is advised for Flowerhorns larger than 3 inches since smaller ones may become frightened by their reflection.

Tank Size

One Flowerhorn cichlid requires a tank with a fixed quantity of 70 gallons. It is not the species for you if you’re searching for a freshwater fish that can thrive in a small tank.

If you want two Flowerhorn fishes to flourish in the same tank, you’ll need to increase the total tank size by another 70 gallons. These fish like wandering and frequently make slow, deliberate circuits around their space. A little more room can go a long way toward ensuring that they can spin about in the tank without difficulty.
