Common Reasons For Swordtail Death
It’s important to keep your swordtails happy and healthy if you want them around for a while. Check the following list of common reasons why a beloved fish died in their tank:
Lack Of Space
Swordtails need lots of room to move around and swim to avoid stress and aggression. Therefore, a tank is not the best choice for swordtails unless you can create a lot of space by separating other fish.
Poor Water Conditions
Swordtails are sensitive to water conditions and require pristine levels of cleanliness. Anything from an uncycled tank, a dirty filter, or a lack of air circulation can stress the fish and cause death.
Aggressive Behavior
If you have an aggressive male swordtail in your tank attacking other females, he will quickly run out of mates, and many of the females will die.
An Inadequate Diet
Swordtails require a varied diet to be healthy, so if you fail to feed them properly, this can cause death.
Lack Of Oxygen
A tank that does not have sufficient oxygen levels is also problematic for swordtail health – it can lead to suffocation and death.
Illness
Swordtails are prone to parasites and other ailments, such as dropsy or fin rot. These can cause an early death if they go untreated.
Excessive Stress
High stress levels can cause a swordtail to die, so if you notice any signs of breathing rapidly or darting out for air, the fish is experiencing high stress levels.
Old Age
Swordtails can live up to five years, but their average lifespan is closer to two. So, there are chances that your swordtails might have died because they got old.

The Top Tips For Keeping Your Swordtail Healthy
Swordtails are the hardiest freshwater tropical fish around, but that doesn’t mean they’re invincible! Here’s a list of things to keep in mind if you want your swordtails to live and keep them from dying for as long as possible:
Appropriate Tank Conditions
Please provide them with plenty of space in the tank. Also, keep a clean tank (don’t forget to regularly change the water, filter it well, and ensure adequate air circulation).
Fill your tank with plants! Swordtails are naturally inquisitive creatures that enjoy investigating new things and exploring their environment to hunt prey in it. So get some live plants (not fake plastic ones) for them, so they have hiding places and plenty of food to munch on.
Maintain Water Parameters
Keep your water clean and in top condition. Any changes can stress the fish, making them more vulnerable to disease or attack from other fish.
The appropriate temperature for swordtails is 76-80 degrees Fahrenheit. The pH and Hardness should be within the pH range: neutral, Hardness (KH): 0-15.
Even the tiniest fluctuation in temperature or pH can change the water’s chemistry and lead to a toxic environment.
Provide Adequate Diet
Please provide them with a varied diet that includes different types of food. Swordtails are omnivorous, so they eat both meaty foods and plant matter. Feed them many live plants (try to vary the type not to overload their digestive system).
Plants are an important part of swordtail’s diet because they eat algae and tiny creatures. Also, make sure not to overfeed them.
Keep Compatible Tank Mates
Keep an eye out for signs of bullying or fighting, and separate the swordtails if you see any aggression developing.
Give them plenty of places where they can hide or swim away from other fish. Otherwise, the larger, aggressive fish nip them all day long.
Don’t overcrowd the tank – swordtails prefer to live in groups of 4-5. Check the make female ratio and keep 1 male swordtail with at least 3 female swordtails.
Keep An Eye Out For Diseases
Diseases such as ragged fins or brown patches on the skin are signs that your swordtail is sick.
If you notice any of these, treat the tank with an anti-bacterial treatment as soon as possible, and don’t feed them for a few days until they start to recover.
Treat any signs of illness immediately by isolating the animal and treating it with medication.
