How To Tell If Your Cory Is Bloated?
Many ways lead to bloated cory catfish. In most cases, a bloated cory catfish looks as if its total body or a specific part of your catfish is larger than usual.
Bloated cory catfish is quite common, especially for those just starting in the aquatic world. But it isn’t normal for your cory catfish to be bloated. It is a warning sign that you will need to fix a problem.

What Is the Main Cause of Bloated Cory Catfish?
If your bloated cory catfish is a female, there is a probability that she is about to lay eggs to give birth to young ones.
When females are set to spawn, they will typically become bloated in appearance and more active than usual.
In this case, you don’t have to worry so much about your fish. All you need to do is set up a breeding aquarium for them.
Once they have laid the eggs, it is time to remove them from your breeding tank and raise their fry in there.
Internal parasites are also one of the possible causes of bloated cory catfish
Internal parasites are one of the possible causes of bloating in your cory catfish. These parasites are worms that range in size from small to relatively large.

If internal parasites cause your cory catfish to be bloated, the bloated appearance will usually be centralized around your fish’s belly (ventral side).
In addition, you can also pay attention to some other signs, such as your fish becoming lethargic, scratching themselves on objects, and losing appetite. In some cases, it is possible to see parasites in your cory’s poop.
It is easy to treat internal parasites, but you should be aware that re-infected is also straightforward and quick. So it is essential to take care properly to prevent infection again.
One of the other possible causes for bloating in your cory catfish is fiber, which typically results from low diets. High protein diets can often be the cause of constipation.
If your catfish is constipated, the bloated appearance will usually be centralized around your fish’s belly and ventral side.
In this case, your catfish may have problems with buoyancy and swim erratically because of the discomfort caused by constipation. They also often become lethargic and stop eating.
Fortunately, constipation in your fish is easy to treat. All you need to do is change their diet, and you can expect the situation to improve within a few days.

Swim Bladder Disease
Most bony fish have a swim bladder, a gas-filled sac that helps them stay buoyant and in the correct position in the water.
Swim bladder disease causes problems with the bladder, leading to a bloated catfish. In this case, bloat will usually be centralized around the fish’s middle.
The leading causes of swim bladder disease are your fish eating too quickly, eating too much, constipation, and gulping air when consuming floating foods. Sometimes unsuitable foods can also be the cause.
Treating swim bladder disease is also easy, as long as you catch it early.

Dropsy can be fatal
Dropsy can affect your fish, regardless of their size and shape. Sadly, it is the most serious among the causes of bloated cory catfish.
This condition is an infection that makes cells within your fish swell up, making your cory look bloated.
In this case, your fish will look like a pinecone. Many people refer to their general appearance as “Pineconing.”
- Improper nutrition.
- Poor water chemistry.
- Weak immune system.
- An increase of ammonia or nitrate.
- Physical damage to the swim bladder.
- A noticeable drop in the water temperature.
- Stress from aggressive tank mates or transportation.
- Other diseases.
Treating dropsy is very difficult, and even if you get proper treatment, dropsy can make your fish die within a few days.
Because of the severity of the disease, you should focus on prevention as it is better than cure in this case.

As most of your cory catfish’s meals come from the aquarium’s substrate, it’s normal for them to eat parts of the substrate accidentally.
Larger things, such as pebbles and gravel, can cause a blockage in your fish, which is often challenging to treat.
So like with dropsy, prevention is better than cure in this case. You should also use a proper substrate for your aquarium.
