Why Is My Betta Fish Hiding?


All of a sudden, your favorite active betta seems like it’s shooting for a hiding place to get rid of its presence. You sure must have struggled to come up with a solution in such a case, but have you ever thought of the reason why they do so?

Here we are to help you! Read on for various potential explanations on “Why is my betta fish hiding?“!

Why Is My Betta Fish Hiding?

Because of carrying the body, which is incapable of dealing with the threat, hiding in self-defense appears to be a natural inclination of bettas. That is also the reason why they are sensitive to the changes in environmental surroundings.

So when you see your dearest fish are finding ways to tuck away, that means something wrong is going on with their habitat. At this point, you have no other choice than to figure out those risk factors, or else your fish will be in fatal danger.

Now, wait for no more to rescue your bettas by digging into some causes that draw them covering themselves up!

1. Poor Water Quality

The first to come is water quality, which is an unstable element that can leave an adverse effect on your bettas at any time. It can even be hard for you to control.

The reason is that dust and germs will have an equal possibility of breaking into the aquarium and harming your beloved pet whenever you touch the aquarium equipment. You also need to pay attention to the amount of chlorine in the water.

Too much chlorine can seriously damage betta’s scales and slime coat. And that’s why dechlorination of water is an indispensable step before welcoming your fish to their new home.

2. Loud Noise

Loud noises are perhaps another cause of prolonged stressful avoidance in bettas. When there is a large fluctuation in sound, it can result in vibrations of the water surface that easily freak out the fish.

Thus, make sure to keep the surroundings quiet, and that’s how you get ways to lengthen the healthy life of your betta.

3. Limited Hiding Spaces

We can also explain this phenomenon by referring to the habits of bettas. It is to say being in a heterogeneous living space, such as a tank dense with plants around, is the only way for them to get secure.

Otherwise, this kinescope is what you will behold when insisting on putting your fish in an open-space environment: they will hide all the time away behind a filter or any other decorations as long as they exist in there.

4. Aggressive Tank Mate

Surely no one on Earth can handle a nasty, aggressive roommate for long, neither Bettas. Especially with their gentle nature to avoid direct conflict, they will opt to hide to escape dangerous attacks and chasing.

Yet, if you let such a situation persist, not only will bettas be anxiously dealing with daily life, but their mental health will also be severely affected.

5. Sickness

Sickness is one of the vital origins when it comes to the unusual behavior of bettas. They will be most vulnerable when they get ill. At that time, hiding will become how they react to protect themselves from external threats.

But how do we tell whether your betta is sick or not? Paying extra attention to areas like their fins or eyes perhaps can help you somewhat. In that way, whenever you see symptoms such as fin rot, crossed eyes, infections, or tumors, you know what you are coping with.

What To Do If Your Betta Is Hiding And Not Eating

Now you’ve got along with the causes resulting in your fish hiding; it’s time to figure out the effective solutions to give a parting shot for this problem!

As a first step towards dealing with water trouble, it is essential to regularly test the ammonia, nitrite, and nitrate levels in the water with a liquid test kit. Water dechlorination or putting additional living plants in the tank can also be a great way to aid in handling the situation.

Then how about managing the loud noises that freak out your fish all the time? Well, it may not be as delicate as you think.

All you have to do is simply move their home away from blaring sources like televisions, radios, or treadmills. Besides, impacts such as touching or pounding directly on the glass tank are what you should also avoid to ensure that your fish are in the healthiest environment possible.

For cases like when you notice that your fish shows signs of illness, of course, it may terrify you at first. But believe us, the treatment will be fairly straightforward if you take action promptly and properly.

Whether you’ve had your fish for a certain time and now without warning, it wants to play hide and seek; then inevitable by that the cause may be some kind of bacterial infection. But don’t rush to panic. Let us show you what you are able to do!

In such a case, closely monitoring them, being alert to any outward indicator, and treating them with mild antibacterial medications will help your bettas recover faster than any other of your expectations.

What if the situation goes even worse? Our best advice would be for you to seek some aids from an expert aquarist or veterinarian.

Does Your Betta Need Hiding Places?

As we mentioned earlier, hiding in self-defense is a natural instinct of bettas. It would be cruel to keep your pet in a bare tank without any decorations.

That way, you’re not only endangering the morale of your fish, but you’re also letting boredom and stress take a toll on them on a daily basis.

Here is the fact people may keep missing out: As with raising any living creature, there will be no other word rather than “irresponsible” if the owner assumes that their only duty is to offer their pet food and shelter.


Betta fish are quite an intelligent species, so you can be sure that avoidance is not just an unconscious act on their part. Now that you bear in mind the most likely causes and remedies make sure it’s not too late to fix it.
