Is Your Betta Fish Dead Or Sleeping

You can easily mistake knowing if the betta is asleep or dead. Here are a few things to observe while trying to distinguish between a dead fish and a fish sleeping in the water.

Even though the betta doesn’t move much while sleeping, if the fish hasn’t moved at all, there is a high chance that it is either very ill or even dead. Try and do the following things while the fish lays asleep or moves slowly otherwise in the tank. Try and notice the color of the fish, whether it is faded or vibrant. Focus on its movements, if they are as usual engaging or slow, dicey, and lethargic. If the fins look unhealthy, there are white spots on its body, with a swollen belly, and eyes look bulging out, you can probably assume that the betta is sick and needs treatment. Even after treating the water, providing the correct supply of food, a good source of light, and managing the temperature of the water, if the fish does not move by itself and has been motionless in the water for long, then one can say that the fish is dead.

What Does It Mean If Your Betta Is Oversleeping Why Does It Happen

As an owner, it is your job to identify if the betta is oversleeping. If they are oversleeping, it is not always a good sign. Bettas oversleep for various reasons. And here is how to identify them.

Temperature Shock

Bettas are sensitive to high and low temperatures. Thats why they become less active because of temperature shock. Always try maintaining a 78-degree tank temperature.

The Tank Light is Too Dim

Dim light encourages the betta to sleep more as it regulates its sleeping hour based on the light. So the longer the tank light stays too dim, the more your betta will sleep.

Hes Getting Bored

Some people overlook this fact, but bettas can get bored if there isnt enough decoration inside the tank to keep it amused. As a result, it keeps on sleeping for longer hours.

Your Betta Might Be Sick

Do Betta Fish Sleep On Their Side

Yes there are Betta Fish that sleeps on its side especially if you have a lot of large leaves inside your Betta Fish Tank. But if there are no comfortable surface to sleep with its side then it may again be a problem with the swim bladder.

If the Betta Fish has a swim bladder malfunction then he may be swimming on his side or upside down since he cannot balance.

How Do You Ensure Your Betta Fish Sleeps Well

A well-rested betta is a happy betta. Lets look at the different ways you can encourage your betta to get a good sleep.

During the day, bettas prefer to nap in the shade while at night total darkness will ensure your betta has a comfortable sleep.

Makes sense, right? I mean, your betta cannot close his eyes, so sleeping with the lights on isnt exactly a fun experience.

Since bettas prefer to snooze in the dark, you should ensure that the lights are off when nighttime rolls around.

Reducing the amount of hours your lights are on is a good thing anyway because it can help prevent algae growth in your aquarium, but thats another story.

If you are like me, and darn forgetful, I recommend grabbing a good aquarium timer for your tank. The timer will turn your aquarium lights off at night and on again in the morning, all without any effort from you!

As for daytime napping, bettas prefer a nice spot in the shade.

Fortunately, shade is easy to provide:

  • Choose a shady location to set up your fish tank, avoiding direct light from nearby windows.
  • Tall or floating plants that are betta-safe help to block out the harsh light.

Ideally, you would want to consider shady sleeping spots for your betta when you first set up your tank. So plan ahead, its much easier to decorate an empty tank than when it is filled with water.

Unfortunately, no two bettas are alike. And even if you provide the perfect snoozing spot, there is no guarantee that your betta will sleep there.

Why Do Fish Sleep And What Happens Then

Like most living organisms, fish need to rest and have the time to restore the normal biological functions of the body.

Continued movements without a pause may cause them to become vulnerable to a reduced activity level and poor responses to dangers.

Several studies have established the fact that fish tend to a reduced level of activity and rate of metabolism at some point of the day because of the need for certain restorative functions to be fulfilled.

The resting period that fish take sends signals to the brain to refresh its memory circuits and save energy. Having brains less complicated than ours, fish may not show the exact same symptoms of sleeping.

Fish have a lot simpler central nervous system than ours, which is why their brains dont contain specific regions as humans. Neocortex, for one, produces certain waves in our brain to make us experience variegated stages of sleep including dreaming in rapid eye movement sleep. Fish can complete the rest without these stages, REM, and dreams.

So, the question how long does a fish sleep is more about how they behave as to the circadian rhythm . The following signs are the clue to our conclusion that fish get sleep:

  • A prolonged state of inactivity
  • A typical relaxed posture
  • A repetitive pattern of inactivity for roughly every 24 hours
  • Reduced responsiveness to external stimuli
