When I was growing up as a child many people and friends often asked me “What’s the point of keeping a pet that you cannot hold, touch, walk or teach?” However, the Flowerhorn was the perfect exception to this question.
Flowerhorns have the possibility to be taught, touched (under very certain circumstances and with caution) and played with. They are very interactive creatures and have been specifically bred for this purpose.
Background On Flowerhorn Cichlids
Flowerhorns, also known as Luohan, were most likely bred from Cichlids. We have hybridized them so much that records are hard to find and only the original breeders of the Flowerhorn knew exactly what Cichlids were crossed.
According to Lorenz (2009), Flowerhorn appeal began in the late 1990’s to the early 2000’s and have continued to get stronger since. Flowerhorns can be expensive to maintain and to purchase.
A Golden Monkey flowerhorn was sold for $600,000 in 2009 at Malaysian exhibition. It is believed in the Far East that owning a Flowerhorn brings good luck and fortune, notably in gambling, and not only does the hump resemble the Chinese god of longevity, but as it grows, the owner’s luck grows as well (FlowerHornKing.com, 2010).

It is very difficult to exactly define what a Flowerhorn is, but we can assume that they came from Mesoamerican cichlid hybrids. Hybrids of any fish species are sometimes looked down upon by some because it diminishes their lineages.
Usually hybrids are created to give off a unique look that couldn’t be produced through other means. However, most of the time the hybridization between two fishes remains in the same genus. The Flowerhorn is unique in that its hybridization occurs between many different genera.
The genera used can be Central American cichlids, trimacs and many other different species. There is some confusion about which exact species created the original Flowerhorn. It stems from the potential value of that type of Flowerhorn, (some are valued at hundreds of thousands and the breeding pair is kept a secret because of this) to simply trial and error with so many different species.

Controversy comes into play when some fish enthusiasts make the arguments that there are over 1000 species of cichlids that would make great candidates for a pet fish that don’t require hybridization. Also, sometimes the Flowerhorn can be mistaken for other species of fish, like the Trimac, which can confuse buyers into thinking that they have a true Trimac.
Creating hybrid fish will dilute the pure genetic lineage that took millions of years and countless generations to create, due to crossbreeding of species between two different genera that would never occur in the wild.
Good ethical breeders will take care of their Flowerhorns and ensure proper breeding habits will take place. However, some breeders do some unethical habits like injecting their Flowerhorns with hormones to increase the size of the male’s hump in a faster amount of time than just letting it develop naturally.
Intentional deformities like no dorsal fins and stunted bodies can seriously harm their health and severely impact their life.
Flowerhorns require a great amount of care and should be researched as much as possible before buying. It is important to know what you need to do to care for your Flowerhorn.
Flowerhorns are aggressive and should be kept alone unless cared for by an experienced fish handler.
Minimum: 90 gallons Recommended: 125 gallons or 150-175 gallons for breeding pairs (if planning on having multiple fish along with Flowerhorn, get as large as you can afford).
Sand or large tile substrate is best.
Test your water regularly and change out the water every two weeks.
Temperature: 75°-85° F
Alkalinity: 6° – 20° dGH<
Short bodied: 4-5 years, long bodied: 8-12 years
8-16 inches depending on the type of Flowerhorn
Diet / Food:
Will eat almost anything laid in front of them. Protein rich and a wide variety of fish food is best. Frozen and dried food can be used instead of live food. Some examples of food include crickets, grasshoppers, shrimp, mealworms, white worms, nightcrawlers and black worms. Three small meals a day that can be eaten in around 30 seconds is usually best for them.
If adding decorations keep in mind that the more the Flowerhorn has to keep entertained with the less it will interact with its owner. Large rocks, driftwood and colorful lighting make for unique environments. Plants can help absorb ammonia, nitrate and nitrite.
Flowerhorn breeding can be a rewarding experience for those willing to try it. It can provide great sums of money if successful breeding takes place. It can also provide more knowledge and experience with handling and caring for Flowerhorns in all their stages of life.
Many male flowerhorns are infertile because of their hybridity and breeding two Flowerhorns together is very difficult. Most breeders will find a cichlid to their liking and in their desired mating Flowerhorn’s genetic history and then breed those two together. Some breeders even attempt in making their own type of Flowerhorn.
Separate tanks for breeding are required so that the Flowerhorn does not harm its mate or other tank mates. A separate breeding tank is best so that you can remove the Flowerhorn and put it back in its home tank after a few days. Clear dividers can be placed within the breeding tank, but there must be flow to allow hormones to pass between both sides.
The breeding tank/fry tank should be at least 50 gallons so that the potential 500-2000 fry can develop and swim away if need be. They preform mating dances that are interesting and specific rituals are preformed throughout all types of Flowerhorn, despite different genes.
The fry should not be touched or moved for at least two weeks. Their tank should have sponge filters and nitrates should be below 10ppm (Buildyouraquarium). After spawning, the female should be removed, but the male should stay to take care of the eggs. When the eggs hatch the male should be removed due to different genetics and that their paternal instincts differ.
For the first month the fry will be dependent on cultures of live food. For the first two weeks they can eat baby brine shrimp, but due to feeding them 5-10 times a day, you must change out the water often. After the first couple weeks they can now eat baby shrimp, large daphnia or scuds. More tanks will be required due to the sheer amount of fry and the differences between size (some will eat more than others). After their first month they can now eat pellets, flakes and worms (but not nightcrawlers).
Most of the fry should be around 2-3 inches at around 3 months and can be sold. However, since Flowerhorns are hybrids many of them will have dull colors and be female. The dull Flowerhorns can be kept, but they should not be allowed to reproduce or be let into the wild.
Gender Differences :
Males will usually be more colorful and have large humps. Their breeding tubes are square and are flat at the end and they also have a V-shaped vent. Females usually don’t have humps, or if they do it will be small, and have a black stripe on their dorsal fin. They have a U-shaped vent and triangle shaped breeding tube.
Flowerhorns are beautiful fishes with many distinctive characteristics like its unique mating rituals, its large hump and colorful patterns. Whether beginner or advanced, this fish will provide a great opportunity to experience an intellectual and one of a kind fish.

The ultimate freshwater tropical fish species perhaps, it's definitely one of the prettiest and can be considered challenging to keep long term.
Another great cichlid that is an excellent parent to it's young.
Named after the famous prize fighter, these cichlids need larger tanks.
