Cats and dogs are very expressive animals. If your dog is sick, it’ll stop running around and cuddle next to you. But what about betta fish? You can’t cuddle with these pets, so understanding them can be challenging. Sometimes, these active fish slow down and struggle even to breathe.
Summary

Seeing your fish lie down at the bottom of the tank can be very stressful, but the reason isn’t always bad. A plethora of reasons can explain their behavior. To understand more about the peculiar behavior, keep reading!
Is It Normal For Betta Fish To Lay On The Bottom Of The Tank?
A betta fish’s incredibly colorful fins look the best when they are flowing in the water as they playfully swim around. Moreover, they’re day creatures. Therefore, seeing them active might be a regular thing for you.
Their bubbly personalities are what make them fun. So when they start to act strange by lying at the bottom of the tank, it can be quite problematic. But before you give yourself a headache, make sure to go through all of the possible causes.
What to do when your betta fish is not eating
Bettas are some of the most common pet fish. So if they’re not eating and laying on the bottom, there’s a tried and tested solution. Each problem has its own solution, so you need to do some detective work and find out the issue first.
1. Cold shock
If you’ve got a hungry and slothful fish on your hands, the tank’s temperature might not be right. The perfect temperature for any betta is 75 to 80 Fahrenheit. These cold-blooded creatures absorb heat from the water. With a decrease in the temperature, they might be unable to move or even eat.
All you need to do is fix your water heater and regulate the temperature by keeping a close eye on it.
2. Swim bladder disease
Swim bladder disease occurs when your Betta isn’t able to swim around, which is caused by either indigestion or constipation. You might have overfed them without annoying them, causing them to get bloated. To keep their digestion in tip-top shape, feed them pieces of green peas since they are high in fiber. After a while, they should be fine on their own.
3. Poor Water quality
A bad environment can stress anyone out, so it’s not surprising that bettas get stressed when the water quality is poor. Unclean water can put their immune systems into stress overload, causing reduced appetite and less energy.
Luckily, fixing your water quality is quite easy. A few water quality tests on your aquarium can help you determine exactly what to do.
Possible causes
Here are the possible causes for a Betta fish to lay on the bottom of the tank.
Sleeping
If you’re a beginner, you might not know that many fish sleep as humans do. Of course, they don’t have beds, so they make do with what they have. Sometimes you might see your Betta catching some z’s on a leaf or even at the bottom of the tank. These fish are diurnal, which means they’re up in daylight.
Betta fish often sleep while lying on their side, which is nothing to worry about! If your pet fish seems fine in all other aspects, then it’s probably just napping.
If you want to treat them like royalty, you could get a leaf hammock bed from amazon for better sleep. Check out the product underneath.

Stress
Stress is a factor in fish too! Like humans, betta fish like to sleep at night. They’ll get confused and stressed if you put them in a well-lit room for longer than hours. To make sure your fish is getting enough sleep, switch off the lights after a while.
Another factor for stress can be a confined space. Betta fish like to swim around, and an aquarium that can only hold 3 gallons is not suitable for them. The detail tank should be about 5 gallons and have enough space for your fish to explore. A few aquarium plants will do the job if you want to keep them engaged.
Other than that, betta fish are loners and don’t like being with others. But they enjoy the company of particular snails and shrimps.
Water too cold
For a tropical fish, 72-82 degrees Fahrenheit is the perfect temperature, which is exactly what Betta like. If the temperature goes too low, their metabolism slows down. It can make them lethargic and also absorb less oxygen.
If you want to raise the temperature of the tank, use a water heater to warm it up gradually. Any sudden change will stress out the fish, and it might even kill any good bacteria.

Water too hot
Bettas might like warmer waters, but the oxygen level gets wonky if the water gets too hot. That’s because warm water releases oxygen much faster than cold water. The temperature doesn’t bother them. It’s the lack of oxygenation that leaves them panting and gasping. You can cool down the tank with a fan or an AC. You could also use an air pump to oxygenate the water quickly.
Currents
By looking at a betta fish, you might assume they’re fast swimmers due to their gorgeous fins. But that couldn’t be further from the truth. Their fins are purely for decorative purposes. To accommodate their slow swimming, you’ll need to ensure your aquarium filter isn’t producing a strong current.
If the currents are too fast or strong, your friend will stay idly at the bottom of the tank.
Old age
Even with proper care and the perfect diet, bettas can only live up to 5 years. As they grow older, they become less active, and they might even swim less. If your betta fish is old, you might notice that it sleeps more or spends more time on the tank floor. Don’t worry. All of that is completely natural.
Swim bladder disease
One of the most common diseases bettas are susceptible to is swim bladder disease. This illness causes the stomach to swell up, which stops the bladder from functioning properly. The swelling in their body makes it difficult for them to swim around as they would normally. As a result, the fish just lay down in the tank or sometimes even float to the top.
Excessive ammonia
Your fish might be a victim of a silent killer – nitrates. Nitrate poisoning also brings out other symptoms, such as fading colors, lack of appetite, and rapid breathing. A mix of these symptoms probably means your water is too saturated with nitrates.
If your fish are exposed to 20 ppm of nitrate, it’s enough to put their health in danger. You’ll need a liquid test kit to fix this issue, or it might kill your aquatic friends. Once you’ve confirmed that the high amount of nitrate is the issue, you’ll need to switch out some of the water to regulate the concentration. Be careful because if you change too much water at once, you’ll stress out the fish!
