Why does my cory catfish keep floating?
Your cory catfish keep floating because of swim bladder disorder.
There can be various reasons that can cause swim bladder disorder to your cory catfish.
Poor water conditions, low water temperature, injury, overeating, and feeding floating foods are the causes behind swim bladder disorder.
Proper treatment is needed in such a case. Otherwise, your cory catfish can suffer from a critical condition and even pass away.
What causes swim bladder disease in cory catfish?
These all causes swim bladder disease in cory catfish:
- Poor water conditions
- Inadequate water temperature.
- Congenital disability
Poor water condition
Bad water conditions can be the root cause behind your cory catfish suffering from swim bladder disorder.
Poor water conditions will result in an ammonia spike by altering the pH level.
An ammonia spike will burn your cory catfish gills, skin, and body, making them suffer from a lot of pain and critical conditions.
Cory catfish are sensitive when it comes to water conditions and parameters.
They will become prone to various diseases and parasites when living in poor water conditions.
Inadequate water temperature
Inadequate water temperature can also be the primary reason behind swim bladder disorder.
Low water temperature slows down the digestive process, which causes the enlargement of the gastrointestinal tract, putting pressure on the swim bladder.
Such pressure can result in your cory catfish suffering from swim bladder disorder.
Overfeeding your cory catfish can also make them suffer from swim bladder disorder.
Overeating can make your cory catfish constipated, and also, they can suffer from a bloated belly.
A bloated belly can disturb the swim bladder resulting in swim bladder disorder.
Feeding food that expands when wet inside your cory catfish’s body can also result in swim bladder disorder.
Food like freeze-dried or dry flake expands when it gets wet inside the fish’s body, resulting in stomach enlargement.
Parasites and bacterial infections can also be the reason behind swim bladder disorder.
Stress and poor water conditions make your cory catfish prone to various diseases and parasites.
This is why poor water conditions are known to be the root cause of swim bladder disorder.
This is a rare case in which a cory catfish is born with a congenital disability affecting its swim bladder.
However, if your cory catfish is born with such defects, the sign will be visible at the early life stages.
A physical injury can also result in a swim bladder disorder.
Cory catfish fighting with other mates or striking with decors present in the tank can injure them, damaging the swim bladder.

For treating swim bladder disorder in your cory catfish, follow these things:
- Place the sick cory catfish in a separate tank.
- Let your cory catfish be empty stomach for 2-3 days.

- Treat your cory catfish with antibiotics if the infection is the cause.
Place the sick cory catfish in a separate tank.
It would be best to separate the sick fish and place them in a separate tank where you can observe them easily.
Keep a low water level so your cory catfish can easily swim around the tank.
Maintain the water temperature between 78-82 °F.
Adding a small amount of aquarium salt will help.
Let your cory catfish have a fast.
If an enlarged intestine or stomach is the reason behind swim bladder disorder, stopping to feed your cory catfish for two to three days will help.
Fasting will help your cory catfish to digest the remaining food.
Feed peas to your cory catfish
After fasting, you can start by feeding peas to your cory catfish.
Boil the peas for some minutes, and remove the skin of the peas before feeding them.
You can continue feeding boiled peas to your cory catfish for some days, and after that, start feeding the ideal food they require to fulfill their dietary requirements.
Treat your cory catfish with antibiotics.
If the reason behind the swim bladder disorder is an infection, antibiotics are needed to treat them.
Consult your veterinarian before treating your cory catfish with antibiotics.
Is swim bladder disorder contagious?
Swim bladder disorder is not contagious.
However, we recommend separating your cory catfish suffering from swim bladder disorder and keeping them in a hospital tank so that you can observe and treat them nicely.
Make sure not to add any decors, plants, or substrate in a hospital tank, as it can make it harder for you to observe your cory catfish.
Avoid adding the water of a home aquarium to a hospital tank, as the water can also be the reason behind swim bladder disorder.
