Cardinal tetra breeding isn’t tricky. But it will require you to provide some special conditions for the fish that are similar to their native environment while they live in South America.
If you want Cardinal Tetras to breed, make sure there is enough space for the Cardinal Tetras to have a safe place in your tank. Cardinal tetras need plants and rocks to shelter from bright light, which is very important because they’re schooling fish that will feel stressed if they don’t have their spot.
When Do Cardinal Tetras Breed?
Cardinal Tetras breed during the warmer months of the year. These fish are from South America and cannot handle cold weather very well, especially when reproducing. Cardinal tetras will also not have any babies if they do not feel comfortable in their surroundings.
When Cardinal Tetras feel stressed out or unhappy with their lives, they will stop eating and eventually die. Cardinal Tetras breed best in temperatures of about 77-82 degrees Fahrenheit, so you must be sure to provide your Cardinal tetras with an aquarium heater if they are not living in this temperature range already.
How Do Cardinal Tetras Breed?
Cardinal tetras are very easy to breed. In addition, Cardinal Tetras care is relatively simple, which makes them an excellent choice for beginner fish keepers. But you should know that they aren’t the easiest species to sex at first glance since both sexes look similar. In addition, you can divide Cardinal tetras’ breeding cycle into two distinct seasons: spring and fall.
Cardinal Tetras have a gestation period of about three weeks. After which, females usually lay several hundred eggs on various surfaces in your aquaria, such as leaves or roots.
Cardinal Tetras are egg scatterers, which means releasing their eggs in the water column instead of keeping them attached to plants or other objects. Their fry hatch within one day and immediately start swimming by using a special organ called an “egg tooth.” These fish can spawn twice per year if kept with proper care conditions.
How Old Should Cardinal Tetras be to Breed?
Cardinal Tetras should be at least a year old to breed. Cardinal tetra fry can be as small as 0.75 inches, but they are still quite vulnerable and cannot compete with the larger fish in your tank for food or territory until they have grown significantly more extensive. If possible, set up a separate breeding aquarium where you keep only Cardinal Tetras and raise fry.
How Can I Breed Cardinal Tetras?
Cardinal Tetra breeding is one of many aspects that make this species popular in the aquarium hobby. Cardinal tetras are small, peaceful characins usually sold for freshwater community tanks by pet stores.
If you want to breed your fish, there are some points you must consider. Such as:
Choose Breeding Partner
You can breed Cardinal Tetras if you choose suitable partners. Cardinal tetra males are usually more colorful than females, male’s fins are longer, and they have a pointy nose. After spawning, each female will produce around 100-200 eggs that hatch after 24 hours of fertilization.
Provide Enough Space
Cardinal Tetras need a tank of at least 20 gallons. In addition, Cardinal tetra breeding requires large space and hiding places, so if you want to breed these fish in your aquarium, they must have the room they need.
Filtration
Cardinal Tetras are very sensitive when it comes to water quality. Therefore, you must use an efficient filtration system for your Cardinal Tetras. Cardinal Tetras are so keen on lousy water quality that even a tiny change in the pH level can be deadly. In addition, Cardinal Tetra eggs, larvae, and fry require clean and clear water to survive and grow properly.
Time of the Year
Cardinal tetra breeding is not possible all year round. So, you must pay attention to what time of the year it is best to breed them.
Cardinal Tetras breed during springtime in their natural habitat. It means that this fish will only spawn around March through May. Therefore, if you want Cardinal Tetras to reproduce in your tank, it is best that have the proper conditions to produce successfully.
Food
Cardinal Tetra fry requires a lot of protein and fat-rich food for them to grow properly. Therefore, you must provide high-quality foods rich in proteins such as baby brine shrimp or infusoria for Cardinal Tetra fry. Usually, most Cardinal Tetras are omnivores, so provide them with high-quality omnivore flake food.
Temperature
Cardinal Tetra breeding is not possible if your aquarium water temperature falls below 70 degrees or above 80 degrees Fahrenheit (21 to 27 Celsius). Cardinal tetra fry grows faster and develops better in slightly acidic waters between pH six point four and seven point two. However, their eggs are susceptible to pH changes, so you must provide them with the proper water conditions for successful breeding.
Water Changes
Cardinal Tetras are also more susceptible to infections when they have just laid their eggs. Or if they feel stressed out due to small water changes in your aquarium. You should make sure not to perform any water changes during Cardinal Tetra spawning and fry growth.
Cardinal tetras are susceptible fish that require a lot of attention to breed successfully. As a result, Cardinal Tetras can be difficult for beginners, but if you provide the right conditions, they will reproduce easily in your tank.
