Kok Genes: The Secret for Flowerhorn Head Growth

Every flowerhorn hobbyist’s goal is to make his flowerhorn cichlid develop a large kok. This is because the size its head is the single biggest determinant of quality and in many cases, its value. Below are some of the flowerhorn head growth secrets you should know as a hobbyist:

The Flowerhorn Kok Gene
The kok gene is the only factor that determines whether a louhan's head will develop into a large one. Without it, nothing you can do that will improve the kok size. The key here is to be able to determine whether your fish has it or not.

In choosing a juvenile fish, select the one that already has a great showing or potential. Expert hobbyists know how to do this. If you are just starting out with this hobby, do not worry. In time, you will just develop this skill naturally.

Do not assume that because its male parent has a huge nuchal hump, your purchase will have too. It is better to spend some extra cash on a great juvenile louhan than deal with the frustrations later.

Given that your fish has already started showing some head/kok growth, here are the things you should look into to enhance it better:

Great Water Quality
Water quality is second in the list since it directly affects your pet's health. Kok development is faster and more stable when your fish is in its best health condition. More tips on boosting the overall health of your flowerhorn.

This means that you should develop and maintain a regular water change schedule. It is recommended to do a 30% partial water change once a week.

If you are using a high performance filtration system, twice a month may suffice provided that you replace or clean your filter accessories regularly.

Feeding Routine
Another key here is feeding you fish with just enough flowerhorn food it can consume in a minute or two. Feeding large pellets to small fishes is also a common cause of poor water quality. Use pellet size suitable to your fish.

Tank Size
Choosing the right tank is essential in enhancing its nuchal hump development as well. 30-gallon tanks are the minimum in grooming a 2-3 inch juvenile. Keeping a single cichlid in a separate tank gives the fish chance to establish control over his territory.
Dominance is a trait that tends to help in the development of nuchal humps. Many hobbyists recommend using a 50-gallon tank as a standard. For matured ones, the right size should be 80 gallons or bigger.

Aquarium Lighting
Aquarium lighting is a key factor in making nuchal humps grow bigger. In selecting the best aquarium light for flowerhorns, light intensity and color are the things you should consider.

Feed Quality
Using the right food in enhancing flowerhorn head growth is important too. For juveniles, protein content should be at least 35% of weight. Popular inexpensive commercial pellets include ALife, Hikari, and New Life Spectrum.
