The majority of the time, swordtail fish swim in mid-tank areas, but what if you noticed your swordtail fish swimming upside down? Is this a sign of something wrong?
Your swordtail fish may be swimming in an uncomfortable way owing to a variety of factors, including poor water quality, illness, irritation, and genetic imbalances.
Whatever reason your fish has taken to swimming upside down, you should seek to address the cause as soon as possible to ensure a long and healthy life for your fish.
In this article, we’ll go through some of the most frequent reasons for swordtails to swim up and down or vertically, as well as methods for resolving these issues.
Why Do Swordtail Fish Swim Vertically (Or Up And Down)?
Poor water quality, Elevated aquarium toxins, or even swim bladder disease could be some of the reasons your swordtail fish is swimming vertically.
In this section, we will talk about some of the reasons behind this particular behavior in fish.
1. Inappropriate pH Levels
The pH level of your aquarium water may suddenly alter, which is a concern for your swordtail fish.
This might happen if you don’t properly acclimate new fish to the tank or if you use untreated tap water.
If the pH in your aquarium fluctuates a lot, your fish will have trouble breathing, which may cause them to swim erratically.
2. Sudden Changes in the Tank
When there are sudden changes in the tank, like a new fish or a change in plants, your fish might get scared and swim erratically. But have you ever asked yourself why?
The main reason behind this is that when there are changes in the tank, the water parameters also change. This confuses the fish and they don’t know how to react to the changes.
One of the changes that take place is the level of oxygen in the water. If there is a sudden decrease in the level of oxygen, the fish will start gasping for air and might even swim to the surface.
3. Inappropriate Temperatures
Just like every other cold-blooded species, the temperature is essential for swordtail fish to manage their internal bodily functions (such as breathing).
When the water isn’t warm enough, they do not have enough oxygen to flow through their bodies. It becomes more difficult for them to swim horizontally in this situation, and if untreated, it may result in death.
4. Elevated Aquarium Toxins
Ammonia, nitrites, and nitrates present in your aquarium water can be extremely poisonous to your fish. If the levels of these toxins are not properly managed, your fish will start to experience a variety of health issues.
One of the first signs that your fish is experiencing ammonia or nitrite poisoning is vertical swimming.
This happens because the toxins attack the fish’s gills, making it difficult for them to breathe. As a result, the fish starts to swim erratically in an attempt to get more oxygen.
5. Genetic Imbalances
In some cases, vertical swimming can be a sign of a genetic imbalance. Fish, such as humans, are born with abnormalities and malformations that can impede their ability to swim normally or even cause early death. Fish with deformed spines, for example, frequently swim at odd angles.
If you notice that your fish are vertically challenged from birth, it is probably due to a genetic mutation. There is not much you can do about it, but you can try to provide them with the best possible environment and hope that they will outgrow it.
6. Swim Bladder Disease
Swim bladder disease is a condition that affects the swim bladder, a sac-like organ that helps the fish to float and maintain their balance in the water.
There are many different causes of swim bladder disease, but the most common one is an imbalance in the fish’s diet.
If your fish is not getting enough protein, they might start to experience problems with their swim bladder. As a result, they will start to swim erratically and might even end up swimming upside down.
If your fish is injured, especially if this injury is in the stomach area, it might start to swim upside down. This is because the injury affects the fish’s swim bladder, which is located in the stomach area.
As a result, the fish is not able to control its buoyancy properly and ends up swimming upside down.
How to Prevent Swordtail Fish From Swimming Vertically?
You can prevent your swordtail from swimming vertically by maintaining a healthy environment for them by checking the water’s temperature, ensuring plenty of circulation, and feeding them properly.
The following are some of the prevention procedures discussed above:
1. Maintain Ideal Temperature
The temperature has a major influence on the happiness and health of your fish. So, it is essential to maintain a water temperature of 65-82 degrees Fahrenheit.
If you can’t maintain this temperature in your aquarium, then you should consider buying a heater.
2. Maintain High-Quality Water
As we mentioned, poor water quality, especially if there are high amounts of ammonia or nitrites, will make swimming difficult for your fish.
Make sure you change the water at least once a week (at least 25% of the time) and use a good filter such as a HOB, canister, or trickle system.
A good filtration system helps keep debris and chemicals out of the water. This is important for an aquarium because you want to keep the water clean and free of contaminants.
You should also invest in an air pump to ensure that there is enough oxygen in the water. The air pump also helps to circulate the water, which is essential for the health of your fish.
3. Allow Proper Acclimatization
When you add new fish to your tank, you should take care to acclimate them to their new environment. This process allows the fish to adjust to the change in water temperature and chemistry gradually.
You should slowly add fish to your tank over some time so that they can get used to their new surroundings.
4. Use a Quarantine Tank
If you are introducing new fish to your tank, you should consider using a quarantine tank. This will allow you to monitor the new fish for signs of illness before adding them to your main tank.
You can set up a quarantine tank by using a fishbowl or small aquarium. Be sure to add a filter and an air pump to the quarantine tank.
5. Include Variety in Diet
Fish, like all other animals, need nutrients to stay healthy and strong. A well-balanced diet will provide them with all of the essential elements they require to live a long and productive life.
So, it is important to include a variety of food in their diet. You can feed them live food, frozen food, pellets, and flakes.
You should also vary the type of food you feed them. This will ensure that they get all of the nutrients they need and prevent them from becoming bored with their diet.
Also, add frozen brine shrimp, daphnia, and bloodworms to flake meals at least once a day. This will also give them vitamin C, which will help them stay healthy by boosting their immune system.
6. Provide Places to Hide
Your fish need a place to call home, and that includes having plenty of hiding places. This will help reduce their stress levels and keep them healthy.
If your fish find such an environment inside your aquarium, they are less likely to swim vertically.
You can provide them with hiding places by adding live plants, driftwood, rocks, and caves to your tank.
7. Add Live Plants
Plants are essential in the aquarium because they help to oxygenate the water and provide a place for the fish to hide. They also help to absorb some of the toxins in the water.
You should add live plants that are appropriate for the size of your tank and the type of fish you have. Java fern, hornwort, and anacharis are all good options for a Swordtail fish tank.
8. Prevent Injury
Avoid any items that might harm your fish in the tank. Also, keep your aquarium free of sharp objects and rigid solid substrates.
Similarly, avoid keeping aggressive tank mates with your delicate swordtail fish that might hurt them.
Be sure to maintain high-quality water, offer a variety of food items, and provide plenty of hiding places for your fish. Most importantly, don’t forget to keep an eye out for signs of stress and disease.
By following these simple tips, you will create a happy and healthy environment for your swordtail fish to thrive.
