What is needed for egg-laying fish to reproduce?
All individuals are essentially ready to reproduce once they reach sexual maturity; however, the aquarist needs to create specific conditions in order to initiate the biological mechanism.
In the wild, tetras procreate during the warm, rainy season when there is an abundance of food in the reservoirs.
As a result, the fish’s owner needs to replicate those circumstances in the aquarium.
Sexual maturity of individuals
Ternetia reach sexual maturity at the age of seven months. Fish that are between the ages of eight months and two years old are the only ones fit for spawning.
Furthermore, an adult individual needs to be long enough (at least 4-5 cm) in relation to other members of the species. Older fish and small fish will not be able to fully extract the caviare.
Habitat conditions
In order to encourage spawning, one must:
- increase the water temperature by 2-3 degrees;
- fish that are chosen as "parents" should be kept on a starvation diet for a day, and then fed abundantly with live food (daphnia, corethra or bloodworms will do).
There won’t be any issues in creating ideal conditions if the aquarium solely holds Ternetia. Raising the temperature can harm some nearby fish, and it also gives other fish the opportunity to steal the Ternetia’s live food supply. For these reasons, spawning preparation is frequently done in a different aquarium.
However, problems frequently occur when Ternetia start to breed in a typical aquarium and the owner is unaware of the process until the very moment of spawning.
Pregnant female, photo example
In exact terms, the female thorns cannot be referred to as pregnant because she merely gains and switches caviar rather than giving birth to live fry. In spite of this, this term is most frequently used for convenience.
It is advised to move the fish to live food, which can include different larvae, bloodworms, or daphnia.
If all goes according to plan, some fish will start to show signs of rounding within a week or so; these are the females, and inside are caviare.
Signs
You have to pay close attention to the female Ternetia now that you have turned up the aquarium’s temperature and started feeding them live food. After one to one and a half weeks, if the environment is conducive to the fish, the "girls" will exhibit a pronounced round belly. Novices might even believe that Ternetia give birth to fry live, but in reality, a large number of eggs develop within the stomach of the female.
How to understand that the female is ready?
The male Ternetia will start to exhibit strong activity as spawning approaches, while the females will start to hide. The "girls" can be surrounded by "boys," who can also push them against the walls and drive them around the aquarium.
What to do if you find a pregnant fish?
As was previously mentioned, fish can sometimes prepare for spawning on their own, without the owner’s knowledge.
All of a pregnant female’s eggs must be spawned, and future Ternetia offspring are not even anticipated.
What happens if the fish is not allowed to spawn?
In the event that spawning is delayed, the fish’s internal eggs will overripen and the fry will stop emerging. Furthermore, in the event that the female does not spawn, the eggs in her body develop into a tumor or cyst, which can cause grave health issues or even death.
Breeding at home, instructions with photos for beginners
Black tetra spawning usually happens without any particular issues. However, if the aquarist hopes to produce offspring from the fish, he must provide them with proper care.
Where to carry out?
As mentioned earlier, it’s usually advised to conduct spawning in a different container. It is challenging to create an environment that is ideal for the "parents," eggs, and fry that have emerged in a typical aquarium.
Breeding in a separate aquarium
It is necessary to set up a separate aquarium (spawning ground) in advance; a tank with a minimum capacity of 20 liters will work well. Ensuring the following water parameters is crucial:
- temperature – from 24 to 28 °C;
- hardness – 5-10 ° dH.
A heater and an aerator need to be installed in the tank, and the water needs to be soft (melted or boiled). However, part of the water needs to be removed from the main aquarium because the fish cannot be abruptly transferred to different environments.
Natural light in the spawning ground is ideal for Ternetia, so no additional lighting is needed. The actual container needs to be placed in a peaceful, isolated area away from irritants and bright sunlight.
To protect the eggs, a lot of aquarists advise placing Java moss on the aquarium’s bottom. The truth is that adult animals expend a lot of energy during spawning, and in order to regain strength, they devour their young right away. It is worthwhile to place a special net with small cells inside the spawning grounds if you are spawning to produce offspring. This net will effectively shield the eggs from hungry "parents."
How to breed in a common aquarium?
Actually, spawning can happen in a regular aquarium as well. This is typically carried out by aquarists who do not require Ternetia fry because raising offspring in a shared tank will be very difficult.
Preparation for spawning
When Ternetia are ready to spawn, some aquarists release them into the spawning ground; others choose the best fish and "start" the breeding process in a different aquarium, not in a shared tank. Regardless, the fish must be transferred in the evening to allow them to acclimate to the altered environment over night.
Should the adaptation prove effective, the males can start pursuing pregnant females early the following morning. Fish may spawn a week later than expected if they need to spend a considerable amount of time acclimating to a new location.
It’s critical to keep the aquarium clean, keep an eye on the suggested water parameters, and feed the fish live food.
If inadequate care is given, ternetes are unlikely to procreate.
The process itself
If spawning has started—which it usually does early in the morning—the males will actively pursue the females, pushing them up against the walls and circling near them. The male Ternetia immediately fertilizes the slowly forming spawn that the females produce. The females continue to spawn for a further two to three hours while the eggs settle on the bottom and are protected by cover. The Ternetia generates over a thousand eggs on average, but not all of them will hatch.
Is it necessary to repeat the process?
Pregnant Ternetia typically spawn four or five times in a row every two weeks, so the entire process can take two to three months.
The fish need to be brought back to the spawning area after the initial spawning in order for them to shed all of the eggs.
What to do if nothing works?
The males and females of the fish should be put in separate containers or returned to the main aquarium if spawning has not taken place after two weeks in the spawning ground. It is important to examine the potential causes of the failure:
- the spawning ground has unsuitable water, and the conditions are very different from the general aquarium;
- fish are sick, lack of appetite (we recommend reading an interesting article about popular diseases of Ternetia);
- irritating conditions in the room (loud sounds, bright light);
- wrong age and size of Ternetia.
Once the issues have been resolved, the fish should be returned to their spawning grounds.
Caring for eggs after spawning, growing fry from eggs and photos
As mentioned earlier, in order to prevent them from destroying the eggs, the "parents" need to be put back into the main aquarium. To guarantee that the spawning ground is free of different fungi and parasites, it is essential to replace roughly 25% of the water and add a small amount of 1% Methylene blue aqueous solution. The lighting in the aquarium can be further dimmed without lowering the temperature.
In approximately one day, if all goes according to plan, the larvae will start to emerge from the eggs. They merely take up space on the bottom, in plants, and on other surfaces at first, not moving at all. Fish larvae have a yolk sac that serves as their initial source of nutrition. The sac will vanish in four to six days, at which point the larvae will have grown into fry and will start to seek for food.
Fry and caring for them
It is essential to restore adequate lighting as soon as the fry become active.
Keeping an eye on the water’s cleanliness during this time is very crucial; you can even do this by adding a few snails to the spawning area. Up to 25% of the total water volume needs to be changed each day.
Small portions must be fed frequently to little Ternetia (at least 4 times a day). They should be fed live dust (solution with infusoria), crushed live food, and special dry food meant for frying.
The fry grow unevenly, with the stronger ones frequently devouring the weaker ones. The aquarist must sort the fish and place the largest tetras in a different container if he intends to keep as many pets as possible. If no one poses a threat, all of the fry can be transferred to a "adult" aquarium after one to one and a half months.
How they reproduce depending on the species?
While the reproduction of almost all tetra species is identical, it is worthwhile to discuss the colored species in greater detail. As you are aware, caramels receive subcutaneous injections of coloring pigment to give them their vibrant color; as a result, their progeny will be dark gray, much like regular tetras.
In response, glofish underwent genetic modification that resulted in the acquisition of an atypical hue, which is inherited.
The aquarist can feel like an experimenter, crossing multicolored males and females, since their fry will inherit the color of their parents. Colorless individuals can also occur in the Glofish litter, though this is extremely uncommon.
Tetra breeding can be a fulfilling hobby for both novice and experienced aquarium keepers. These little fish breathe life into any aquarium with their vivid colors and energetic personalities, and raising a successful offspring can be immensely fulfilling.
Anyone can enjoy breeding tetras if they follow the correct procedures, which include choosing healthy breeding pairs and setting up the ideal habitat for their fry. Since these delicate fish need particular conditions to survive and reproduce, patience and attention to detail are essential.
Never forget that every breeding endeavor that succeeds broadens your knowledge and experience. Thus, take your time, pick up from any mistakes you make, and enjoy seeing your tetras grow and thrive in your care.
For both novice and experienced aquarium keepers, breeding tetras can be a fulfilling endeavor because it provides an opportunity to witness the amazing life cycle of these colorful fish. Whatever one’s level of experience, this guide breaks down the necessary steps to successfully breed tetras, from setting up the ideal breeding tank to taking care of the fry.
