Can loud music disturb betta fish?

In this post, we will learn a little about the relationship between betta fish and loud music. We will also outline if loud music can disturb the betta fish.

Can loud music disturb betta fish?

Yes, loud music may cause them to become stressed. The fact is, bettas have an ear and along with it a good hearing. however, the limitation of living in water can affect the perception of sound. In a way, bettas have a sense of what is happening outside the tank. Let’s take a closer look at this.

Betta fish and ears

Betta fish have ears, although you may not be able to see them. A thin layer of skin covers their ears, which are located on the sides of their heads. While their skin shields their ears from the water, it nevertheless has a significant influence on their ability to hear.

In water, sound travels four times quicker than in air, yet making a sound underwater is more challenging. It’s not quite as loud as screaming in the air, as anyone who has done so in a pool will attest to. Because your head is underwater, you can’t hear as loudly as if your head were above water when someone screams close to you.

However, even with their good hearing, it is still difficult for them to hear what is happening outside of their tank. Although your betta is unlikely to learn to identify your name, it may be able to understand some words and phrases you speak.

Predators can occasionally be heard approaching before it is too late for them to evade them.

They can also find prey by using their hearing and then sneak up on that prey undetected.

Betta fish and vibration 

Songs with a lot of vibrations are not suitable for fish to hear, even if they make a lot of noise. However,  tapping on the glass is bad for fish because fish are incredibly sensitive to vibrations, and it’s not the sound of someone tapping on the glass, but rather the loud vibrations that reverberate throughout the tank that cause an issue in the first place.

Because of sensitivity betta fish might be able to jump out of the tank because of long-term vibrations exposure. Once they are subjected to persistent vibrations, all bettas will do all in their might to get away from those vibrations.

As previously stated, some sounds, particularly loud ones or ones that generate excessive vibrations, might be dangerous to your fish.

Betta fish and music

Betta fish can detect music by sensing the vibrations it emits, but they can’t listen to it the way humans do. A betta’s ears will not perceive music in the same way that ours do.

Because of their small size, the vibrations felt by betta fish may be limited to a certain number of frequencies, each of which correlates to a specific note and loudness.

There’s a belief that betta fish can recognize particular phrases and commands since they are highly intelligent animals. Even though they cannot hear the words uttered, bettas will be able to recognize a familiar pattern of vibrations if the same phrases are said often.

Sound waves are likely to be magnified through the glass of a betta aquarium, as has been reported by many betta fish owners. The fish will be able to hear and respond to any vibrations that enter the tank because of the multiple glass walls.

Do betta fish suffer harm if they are exposed to loud music?

Loud music can stress betta fish because of their heightened sensitivity to sound. The fish’s pressure-sensitive receptors can be damaged by excessive noise, resulting in hearing loss and difficulty navigating, which is bad for any pet.

Betta fish have what is termed a “lateral line”, which is a line of pressure-sensitive sensors going across their body in, well, a lateral line. These sensors are carefully tuned to catch any tiny tremor in the water. They operate as a fish’s eyes in the dark and help fish swim around and avoid decorations, and one another, as they would when they can see.

Sudden vibrations, strong vibrations, or regular vibrations can all interfere with a fish’s ability to use this sense. Without this sense, they will be left blind at night, which would force them to run into decorations, perhaps harming themselves in the process.

Prolonged vibrations may also cause great stress to fish, and when it comes to bettas, it can force them to jump out of tanks. While all bettas are jumpers, if they are subjected to persistent vibrations, they will make it their duty to get away from those vibrations by any means possible. 

Since they can distinguish stimuli outside of aquariums, whether it be music or their owners’ speech, this doesn’t imply they can passively listen to just anything. As previously noted, some sounds can be downright dangerous to your fish, especially loud ones or ones that generate excessive vibrations.

Louds songs are no good for betta fish 

many aquarists already know that water molecules vibrate in response to sound. An issue might arise when the water molecules are vibrated excessively. This might cause distress to the fish and potentially injure them.

You should avoid playing High-Beat music all day even if your betta is mute and doesn’t respond well to it. Make sure your speakers aren’t aimed at the aquarium if you’re using them.

If you have a betta tank in your room, put on your headphones and listen to some uptempo music. It’s also a good idea to keep the volume down.

Frequently Asked Questions (FAQs): Can loud music disturb betta fish?

How loud of a volume tolerance do betta fish have?

Because sound travels five times quicker in water than in air, it may have distinct effects on fish. Hydroacoustics is the study of sound underwater. Prevent your fish from stress and keep the volume down as well as the vibrations that are close to the aquarium.

Is my fish going to be harmed by listening to too much music?

In most cases, vibration/noise is not considered to be safe. In particular low-frequency bass, which the fish sense as vibrations and react to in the same manner as a tap on the glass does, which causes them to dart around 

Is it true that music has a calming effect on fish?

Some fishes are drawn to some noises and vibrations, while others are less appealing to the fish. While some forms of music and sound are repulsive to fish, others are enticing.

Do betta fish get bored?

Your betta may get bored if you keep him in a tiny tank with no decorations and give him the same food every day. As a result, boredom can lead to feelings of melancholy and exhaustion.
