Flowerhorn Cichlids are human-made. They’re never found somewhere naturally in the wild, if they are, they’ve been introduced by humans.

Red Devil, Trimac Cichlids, and Blood Parrot Cichlids were imported from Central America to Malaysia. The Red devil and the Blood Parrot were bred together, creating the Flowerhorn. 

They were first produced in Malaysia, Thailand, and Taiwan. Asian fish hobbyists then took a liking to Flowerhorn Cichlids.

US and European hobbyists keep them, but importing Flowerhorn Cichlids is banned in Australia.

The first generation of Flowerhorn cichlids available on the market was the Hua Luo Han. They were bred in about 1998. Since then, their hybrids became quite popular.

The Seven Colors Blue Fiery Mouth (also known as the Greenish Gold tiger), was imported from Central America and crossbred with the Jin Gang Blood Parrot from Taiwan.

This breeding made the first breed of Hua Luo Han flowerhorn hybrids.

Their life span is about 10-12 years.


Flowerhorns are among the most vividly colored in the cichlid world. Males are more colorful than females, and they also have a ‘nuchal hump’ or ‘Kok’ on their foreheads. 

Both sexes have flat, long bodies, with long dorsal and anal fins extending to the tip of their tails. Their pectoral fins are translucent and much shorter than their others.

Both male and female fish can grow up to 30-40 cm in size.

The key to differentiating male flowerhorn cichlids from other fish is their hump on their forehead. Females don’t have any.

Flowerhorn fish come in an extensive range of assorted colors, from light to dark, purple to red and gold.

You’re sure to find your favorite color in the extensive range of flowerhorn cichlid strains.

How To Tell The Sex Of A Flowerhorn Cichlid?

Here are a few pointers to help you determine the sex of the fish.

Markings and Colours: Males have more pronounced and vivid colors than females, making them stick out more. Females have black spots on their dorsal fins. Males tend to have longer dorsal fins and anal fins.

Size and Shape: Males have a large nuchal hump on their forehead. Males are larger than females.


These cichlids should successfully breed if you follow these steps and ensure they will be as comfortable as possible.

Before you breed flowerhorns, note this: Most flowerhorns become fully-grown and prepared to reproduce at 1.5-2 years. You usually don’t need to interfere or encourage the spawning procedure.

Important pointers

  • First, put both cichlids in a tank in which size suits the measurements of the breeding pair.
  • In the breeding tank, there should be 3-4 females per 1 male, all the same species to avoid hybridization. Don’t get two males. Otherwise, both will try to kill the other.

When the female lays her eggs (usually on a flat surface), the male fertilizes them. If the male becomes hostile, you can separate him from the fry using a divider.

Two days later the eggs hatch and the youngsters will begin swimming about after two days more.

Flowerhorn Cichlid Care

Make sure to monitor your fish, as, unfortunately, it’s common for them to suffer from diseases such as a hole in the head and digestive blockages.

Conditions Of The Tank

The flowerhorn is a slightly high maintenance fish and needs a huge tank. It’s best to have a filter. They make a mess when they eat, and they thrive best in clear water.

They like digging, so having plants isn’t the best idea, rocks are a better choice.

You should also clean the water weekly.

Seventy-five gallons is the minimum tank size for an individual. For a breeding pair, they require 150 gallons or more. But it depends on the size of the fish.

Water Parameters – PH And Hardness

Keeping the hardness and pH in good order is very important to the health of the flowerhorn cichlid. If the parameters aren’t right, the fish will get sick.

pH: 7.4 – 8.0. 

Hardness: 9-20 dGH

Water Parameters – Temperature

The best water temperature for these flowerhorns is 78.8-86 degrees Fahrenheit. 

Suitable Tank Mates

It’s best to keep these in a maximum of one breeding pair per tank, or one individual. You can raise them together as juveniles, but once they reach adulthood, separate them, so each has their territory.

Avoid having other tank mates, especially those of different species, because fights and the other fish being hurt will be a common occurrence.

What To Feed Flowerhorn Cichlid?

You can feed them directly from your hand, as they’re not afraid of you, but careful, as bolder ones will bite!

If they refuse to eat, usually a clear sign they’re sick, as these cichlids have a very hearty appetite.

Feed them about two to three times a day, and adjust the amount as necessary.

Your Cichlid Questions Answered

What Is The Puffy Part On A Flowerhorn Cichlid?

The puffy part is called a nuchal hump or Kok. It appears on the male flowerhorns and not the females.

Where To Buy Flowerhorn Cichlid?

In general, the best place to buy one would generally be online and get it delivered or buy the flowerhorn at your local aquarium store.

Why Won’t My Flowerhorn Cichlid Eat The Pellets?

One of the most common reasons why your flowerhorn won’t eat food is because it may be stressed. Stress has a significant effect on these cichlids and will cause them to lose their appetite for a couple of days. 

Uneaten pellets and food will cause ammonia. You can utilize a small siphon or turkey baster to get rid of them.

Can I Keep My Flowerhorn Cichlid With An Oscar?

Indeed you can, but ensure the oscar is mature and defend itself from the flowerhorn’s attacks. If the flowerhorn is fully grown and powerful, it may kill or attempt to kill the oscar. 

Before you buy the fish, note:

  • You put the oscar in the tank before the flowerhorn; the flowerhorn will not accept the oscar in its tank if you put the oscar in after the flowerhorn.
  • Both fish are the same size as each other
  • The tank is a suitable large size

If you’re looking for a peaceful fish with peaceful tank mates, flowerhorns aren’t a good idea. Sometimes, the flowerhorn will be friendly with its tank mates.

But, it depends on the size of the tank, and the nature of the flowerhorn.

Can Flowerhorn Live With Cichlids?

Yes, but keeping a cichlid/s with flowerhorns is a challenge. Being an aggressive fish, flowerhorn cichlids won’t take kindly to multiple tank mates.

How Big Do Flowerhorn Cichlids Get?

Being 16″ (40.64cm) at a maximum and 12″ (30.48cm) at a minimum in length, these are huge fish!

Are Flowerhorns Aggressive?

Yes. Flowerhorns generally are aggressive. Males are especially aggressive during breeding.

Flowerhorns are almost otherworldly, due to their unique range of coloration and nuchal humps, a truly spectacular fish.

Though a bit to handle and manage, it’s definitely worth it if you’re up for the challenge.
