The color morph known as "Cuban swordtail" is the consequence of hybridizing Geller’s swordtail with other pecilia, specifically the tuxedo pecilia in this instance. The mountain swordtail is essentially the only pure species of swordtail found in aquariums in Russia and Ukraine. The remaining swordtails are all hybrids. Everything: koi, green, black, white, crimson, brown, gray, etc.d. etc.p., tiger, flag, etc. All of these are crossbreeds between tricolor and spotted pecilia and swordtail Geller.

The requirements for maintaining Cuban swordtails are the same as those for other species.

Class: Fish with ray fins.

Tooth-carp is the order.

Peciliidae is the family.

Conditions for aquarium maintenance:

The water is between 22 and 26 °C.

(is able to withstand a brief dip in temperature to 15 °C)

PH of "Acidity": 7.0–7.5.

Hardness dH: 6–20°

10% of behavior is nonaggressive.

Maintaining: not difficult at all.

Swordtails are native to Central America, specifically to southern Mexico and Guatemala. They reside in reservoirs that are heavily covered in a variety of aquatic plants and have stagnant, slowly moving water.

Swordtail fish, or Xiphophorus helleri, are members of the pecilia fish family. Translating Xiphophorus helleri from Greek means "sword" (xiphos) and "to carry" (phoros). The German natural scientist Karl Bartolomeus Geller, a swordsman, was given the prefix "HELLERI" for catching these fish in Mexican lakes and bringing them back to Europe in a safe manner.

Compatibility of swordsmen

The swordsmen don’t use force. They work well with nearly all peaceful medium-sized fish. Tetras, Minora, Ternetius, Danio, all Pecilium fish, and t.D. are some of the best neighbors. Nearly all bottom fish, including Platidoras, Antsistrus, Platidoras, and corridor fish, are compatible with them. For example, they get along well with Scalars and other "peaceful" cichlids.

When swordsmen come into contact with large, aggressive fish, like cichlids (akara, astronotics, diamond cichlisoma, etc.), they become incompatible. Furthermore, it’s not a good idea to place them with "veil" fish because swordtails can "pinch" them with their fluttering fins because the latter are slow.

Male swordtails can be aggressive and intolerant of one another. There have been incidents where men have fought and even hurt one another. Consequently, swordtails should be housed in aquariums in haremas with two to three females for every male. Fish are noticeably less aggressive within their own species in this instance. Check out the article on aquarium fish compatibility.

Life expectancy of swordtails

By aquarium standards, swordtails have a medium-long lifespan. In ideal circumstances, their lifespan may reach five years. This link will tell you how long other fish live!

Minimum aquarium volume for swordtails

Small aquariums are home to many inexperienced aquarists’ swordtails. This isn’t totally accurate, though. Swordtails are actually pretty big fish. Additionally, the minimum aquarium size for a harem family of swordtails should be 50 liters, as it is advised that they be kept in a ratio of one male to three or more females. A large aquarium is ideal for swordtails; one hundred liters is preferable.

See HERE for details on how many fish can be kept in an X-liter aquarium (links to aquariums of various sizes are located at the bottom of the article).

A vibrant and resilient freshwater fish that brings a burst of color to any aquarium is the Cuban swordtail. This fish, which has a unique sword-like tail, is well-suited for novices as it requires little maintenance. It does best in communal aquariums where it can live in harmony with other non-aggressive animals. Cuban swordtails can live healthy lives and add vibrancy and movement to your aquatic setup given the correct conditions and care.

Care requirements and conditions for keeping swordtails

Swordtails don’t require any unique circumstances. In actuality, the secret to their wellbeing is keeping aquarium water at ideal parameters. Nevertheless, remember this:

1. Swordtails definitely need aeration and filtration, weekly replacement of up to 1/4 of the volume of aquarium water. It is worth noting that these fish do not need a lot of oxygen, and too frequent change (replacement) of aquarium water is not as beneficial for them as for other types of aquarium fish. Therefore, if you change the water less often, for example, once every 14 days, and not every 7, nothing bad will happen. This rule is appropriate with a stable biobalance and zero nitrogen: NH4, NO2, NO3. As for any other fish, a high concentration of poisons is unacceptable: ammonia, nitrites and nitrates. Every conscientious aquarist should always have a set of drop tests on hand, at least for nitrate and phosphate. Fortunately, they have now become inexpensive, there are no problems with their assortment and acquisition. In the stores of your city – offline, you can find inexpensive Vladox tests. Watch out, friends, for nitrogen compounds, keep them in check and everything will be fine for you and your pets.

Using preparations that neutralize harmful substances with clean water during deep water changes won’t be unnecessary. For example, Tetra AquaSafe eliminates heavy metals and chlorine compounds while also including B vitamins, iodine, and other beneficial ingredients for aquariums.

2. The fish are nimble and can jump out of the aquarium and perish, so it needs to be covered with a lid.

3. Swordtails, like many other fish, are at ease in the presence of greenery. It is advised to use riccia, vallisneria, echinodorus, cryptocoryne, duckweed, and other plants as aquarium plants for them. Plant thickets are an imitation of a fish’s natural habitat.

4. You must set up an area that is open to swimming when decorating an aquarium. Swordtails have superb swimming abilities. Shelters are not necessary for swordtails.

Feeding and diet of swordtails

Swordtails are omnivores with an easy way with food, and they tend to overeat. They enjoy eating chips, granules, and flakes that have been dried or freeze-dried. Tetramin can be used as a basic feed with ease. and feed that also contains carotenoids.

Allow small note. Color series feeds – enhance the natural color of fish (red, yellow colors), as it is enriched with pigments such as canthaxanthin, astaxanthin. In fact, carotenoids are natural "coloring" substances. It is astaxanthin that gives plants a red-orange color, carrots are a striking example of this. Or, for example, have you ever wondered why flamingos are pink? Yes, that"s exactly why. Eating plant and animal food rich in carotenoids, flamingo plumage, which is initially white, gradually turns pink. The more birds get this substance with food, the richer and redder the plumage becomes. If you look even deeper, flamingos eat the well-known brine shrimp – pink, saltwater crustaceans and also turn pink.

In actuality, if the meal includes carotenoids, the same thing occurs with fish. We also point out that astaxanthin is an antioxidant, among its other beneficial qualities. Generally speaking, carotenoids benefit all aquatic life, including aquarium plants, in addition to fish. The only requirement is that everything be balanced and in moderation. You must realize that the conditions of the fish’s life—such as stress or spawning—as well as the environment and lighting in the aquarium all affect the fish’s color.

In conclusion, while the Color series feeds are beneficial, they shouldn’t serve as the main course. Imagine what would happen if someone consumed nothing but beets for the entire week. The idea is unsettling. Fish is the same way. I apologize; they start to poop adorable pink poop.

It is crucial in this case, incidentally, to avoid overfeeding the fish in order to prevent digestive tract issues. Once a day, feed the swordfish, and observe fast days. One of the keys to their maintenance success will be this. It should be mentioned that when purchasing any dry food, you should be mindful of the manufacture and expiration dates, avoid purchasing food in large quantities, and store it in a closed environment to prevent the growth of harmful flora.

Reproduction and breeding of Cuban swordtails

Swordtail breeding is not at all a difficult undertaking. Breeding guppies and other livebearers is comparable to this. It can also be said that it genuinely occurs on its own.

Swordtails reach sexual maturity between the ages of 5 and 6 months. It is advised to maintain the fish in a ratio of one male to three females for breeding purposes as well as for their own comfort. The male does shuttle movements back and forth, resembling a mating dance, while courting the female.

Mature eggs are fertilized inside the female. This might take a few days to complete. One noteworthy characteristic of swordtails is their ability to procreate multiple times after fertilization, even in the absence of a male.

The woman is expecting a child in four to six weeks. The conditions of the aquarium’s water, temperature, lighting, and feeding affect this time frame.

A "black pregnancy spot" appears under the tail of a pregnant female, and her belly is swollen. A few hours before "giving birth," the female is said to start moving more actively and "rushing" up and down the aquarium glass, causing her belly to become "square."

The female can spawn anywhere from fifteen to one hundred fry at a time. Typically, spawning takes place in the morning.

Monthly births are possible if the water is between 26 and 27 °C and there is ample feeding.

Ensure the survival of the young is perhaps the most crucial rule to follow when breeding swordtails. Regretfully, the parents consume their own young, and since swordtail fry are big and vividly colored, this process essentially becomes eradication. In the wild, swordtails never get to see their young since the current whisks the fry away as soon as they are born. The parents take the fry out of the aquarium to eat.

The aquarium is heavily planted with aquarium plants in order to preserve the progeny. In the aquarium, plants are arranged densely on the surface, in the water column, and on the bottom. Thus, the majority of the fry survive because the young are given refuge "from evil parents."

Additionally, you can use specialized spawning tanks, which are made like funnels with the female remaining inside and the spawned young falling out into the spawning aquarium, to preserve the offspring. As a result, the producer and the young don’t interact at first.

After spawning, separating the producers is the third way to preserve the progeny. This is an easy option, but it does require the aquarist to be punctual and focused.

The female is kept apart and fed copiously following spawning.

Young swordtails are fed live dust (nauplii, brine shrimp, cyclops, microworm, rotifers, and cut tubifex) as their first meal.

A week later, the young swordsmen start to separate; the strong and "thoroughbred" are destroyed by the weak and flawed.

The juveniles grow quickly; males’ anal fins start to change after two months, and by the third month, the "sword" starts to grow.

Independent crossing happens when keeping swordtails from different species, and this can occasionally produce stunning offspring.

One fascinating aspect of these fish’s existence is that a female swordtail has the ability to change gender at some point in time. This occurs when there is a "shortage" of males, which makes sense given the species’ struggle to survive. Almost 90% of the progeny born to a pair of females and one former female are female.

Diseases and treatment of swordtails

Since swordtails are tough fish, they can withstand harsh confinement circumstances. But like all living things, this kind of great health doesn’t last forever. Making sure the aquarium water is at its ideal temperature is essential for the successful retention of fish.

Swordtails require the same care for all common aquarium fish illnesses, with no special considerations.

The disease must be identified in order to treat swordtails correctly, and then the required measures must be taken. This will support you. Diseases and treatments for aquarium fish as well as website sections: Aqua. Med. Fish Diseases.

These and a variety of other fish are always available at the physical supermarkets Aqua Logo and the internet retailer Aqua-Shop. Live goods delivery is offered in Moscow and the surrounding areas.

A fascinating and colorful addition to any aquarium, the Cuban Swordtail breathes life and color into your aquatic setting. It is a fantastic option for both novice and expert fish keepers due to its eye-catching red and black colors. It is also relatively easy to care for.

Because of their reputation for tranquility, these fish make excellent companions for other non-aggressive species. They can show off their lively habits and humorous personalities in a well-kept tank with clear water and lots of swimming space.

The Cuban Swordtail is an excellent choice if you’re searching for a vibrant, low-maintenance fish that will enhance the beauty and charm of your aquarium. They can flourish and brighten your aquarium for many years to come with the right care and attention.
