Do Betta Fish Shed Their Scales?

Betta fish are some of the most popular pets in the world. They can be purchased at pet stores, and even online! But do they shed? It’s a question that many betta owners want to know.

In this blog post, I talk about the question of betta fish shedding, and whether or not they do. I’ve done my research on the answer to this very important question, so let’s take a look at what I found out!

Do Betta Fish Shed?

No, healthy betta fish are not supposed to shed their scales. In fact, if your betta fish is shedding scales, it could be a sign that something is wrong. It’s important to keep an eye on your betta fish and watch for any signs of illness or disease.

Keep reading to find out the possible reasons that your betta fish could be shedding scales and what you can do to prevent it from happening again.

If you notice that your betta fish is shedding a lot of scales, take him or her to the vet immediately for a check-up. If you don’t know where to take your betta, contact the owner of an aquarium store. They will be able to refer you to a local veterinarian who can treat fish for minor ailments.

Why Is My Betta Shedding Its Scales?

I will now talk about what causes a betta to lose its scales. Here are the most common causes for this to occur:

Physical Injury

The most typical cause of an active fish to shed or lose scales is some sort of physical damage from one of the following causes:


Bettas are known as Japanese fighting fish, which means that they are known for their aggressive tendencies. When two male bettas are placed in the same tank, they will often fight until one loses.

During a fight, scales can be torn off or ripped away from the fish’s body, which can lead to shedding. This can be avoided by keeping your betta in a separate tank.


If you aren’t careful when you’re handling your betta, you could end up injuring them. If a betta is handled too roughly, scales can be ripped from their body causing similar shedding as fighting.

For your safety and for the safety of your fish, only handle your betta when absolutely necessary. They shouldn’t be stroked or pet as this can remove their slime, as well as their scales.

Infection And Disease

If your betta is often sick or diseased, they can begin to shed scales. Most of the time this will be due to some sort of infection that causes them problems with their gills and fins.

This is a more serious problem than casual shedding because it could lead to illness or even death if left untreated for too long.

Infectious Protrusion

This is a disease that is typically found in betta fish who are living in poor water conditions. It’s caused by bacteria and can be very dangerous if it spreads to other fish or bettas.

If your betta has this condition, their scales could start falling out due to the problem being too much for them to handle on their own. This is a very serious disease and should be treated immediately if you think your betta might have it.

Other symptoms include lethargic behavior, which means your betta spends a lot of time near the bottom of the tank and not swimming about as much as usual.

Over-the-counter medication can be used to treat this disease, but it’s best to take your betta fish to a veterinarian if you’re not sure how to treat the problem.

Poor Water Quality

If the water quality in your tank is poor, it can cause many problems for your fish, including shedding scales. If the water is too dirty or has too much chlorine in it, it can irritate the fish

You can prevent this by keeping the water clean and changing it often, as well as using a good quality water filter.

How To Prevent Betta Scale Loss?

The origins of scale loss are important in determining how to prevent it. I will now talk about the things you should and shouldn’t do in order to prevent scale loss from occurring.

Fighting and Breeding

You can prevent scale loss in bettas by not allowing them to fight or breed. This means you should never keep two male bettas together and always keep a breeding tank separate from where your fish live.


Handle your betta as little as possible, if at all. If they are handled too roughly it can cause their scales to come off. In fact, even touching a betta fish can remove some of their slime, which is important for protecting their scales.

This may be sad news to those of you who like to stroke their pets, but it’s important to be mindful of the fact that bettas are not built for human interaction.

Disease Prevention

Preventing your betta from getting sick or diseased is the best way to ensure that they won’t start shedding scales. Make sure their water quality and tank conditions are as good as possible

Do not use any chemicals in the water unless absolutely necessary, such as chlorine remover for tap water. Also, avoid overfeeding them.

Will My Betta’s Scales Grow Back?

Yes, the good news is that scale loss is not permanent. They will grow back within a few months, but during this time you should make sure that your betta is living in the best possible conditions to ensure their health.

No matter what caused them to lose or shed scales, it’s important for pet owners to pay attention and learn more about how they can prevent scale loss from


In conclusion, betta fish are known for their tendency to shed scales. This can be prevented by keeping them in a separate tank, handling them as little as possible, and ensuring that the water quality is good.

It’s also important to keep your betta healthy so they don’t start shedding due to infections or diseases. If you take all of these steps, you will greatly reduce the possibility of scale loss.
