At, first one should keep a partition between both male and female Flowerhorn and then after a week under constant observation if it is noticed that they don’t show each other aggression it can be concluded that they are compatible enough to breed. After mating, the female will lay eggs and the male will try to fertilize them. Both play equal parts in parenting and taking care of their offspring.

Time span for Flowerhorns eggs to hatch:

A female Flowerhorn can lay up to 700-1000 eggs at a time on a flat base. Both will try to protect and guard the eggs. At this time being too much protective they can lose their temper and can start showing aggression to each other. There is a possibility that they will destroy their own eggs while fighting with each other. Or can even try to eat their own eggs because of their wild nature.

Usually, it takes about 3-4 days to get fertilize for hatching. They get hatched in 1-2 weeks depending on the care taken. Only 5% of the total laid eggs get hatch into little offsprings. One can start feeding them as soon as they start swimming after 5 days post-hatching as they are a very rare and hybrid species. Their hatching rate is very low compared to other fishes.

Even the female Flowerhorn fish laying eggs can eat its own egg when she is aggressive and badly hungry.

• One should regularly feed the female fish in order to not let the hunger affect the eggs.

• To keep in mind that the female Flowerhorn is not disturbed while hatching and taking care of her offspring. Not to keep the tank where there is constant human interaction happening in the background.

• One should prepare the fishes first before making them breed.
• Also one should give time to the female fish after breeding so she can be calm enough while laying eggs.

• Use of Methylene blue should be done so that there are no chances of fungi to appear on the eggs. Or else the fish will eat the eggs along with the fungi.

• The female will take one hour to lay eggs, so for her privacy, there should be no disturbance in any case.

Male and Female Flowerhorn Fish Protect Eggs

Artificial Hatching / Incubation Tank:

Most of the owners of this particular breed have started taking the eggs laid by this fish and hatch them separately in a different tank. If the eggs are incubated and hatched artificially there are more chances of getting great numbers of offsprings. It is indeed a good option when one is trying to hatch the eggs for the first time. Other than this, there are chances that there is some or other issue with the female fish.

These issues can be listed as follows:

Water parameters for hatching eggs:

One should have an idea of what are the ideal ways to prepare an incubation tank of Flowerhorn fish eggs to hatch. The tank shall not be shallow and contain less water. It should be at least 10 inches deep also can exceed up to 14 inches. There should be made the use of methylene blue mandatory so that the fungi do not appear on the eggs and create a protective layer on it.

Water temperature should have a regular check which should be 28-30 degrees Celsius. One can also use aquarium heaters in cold weathers if needed. Water shall not have more saline content that makes it hard. This will degrade the hatching quality.

So there should be mandatory use of water filters. Hard water can make the surface of fish eggs very rough. Other than water and temperature control, one can add air stones to aerate the tank. Similarly, sponge filters can also be used instead of air stones.
As mentioned before, there is a noticeable decrease in the rate of hatching eggs in hard water but also there are chances of the off-springs to get physically handicapped by birth so one should regularly filter the water in the tank.

Poor quality of water will surely result in losing a lot of eggs if not filtered regularly. Also when the temperature in such filtered water, it will increase the level of hatching eggs. Depending upon the fish type, size, and age, the eggs will develop and grow to be a healthy offspring.
Also, it might depend on the tank size and its dimension has the baby fishes will require more space to swim. Some other parameters can also be considered for the degradation in the quality of fish eggs which depend on the breed and species.

    • I don’t think that separating the female from the eggs would be a good idea. You should just separate the male and female and if possible, keep them in the same tank with a divider.
