Why does my betta fish stay at the bottom of the tank?

Seeing your betta fish at the bottom of the tank can be concerning especially if it’s an unusual behavior from their regular daily activities.

Here are the most common ones why your betta fish lays at the bottom of the tank:

Temperature Shock

When you move bettas from a warm or cool tank to another, it’s possible that they might go into shock. Any sudden changes in your tank’s temperature can lead to your betta to stay still or lay at the bottom of the tank. The optimal temperature of the tank should be between 74° and 79°F.

You can also turn off the lights on your fish tank to let your betta rest.

Ammonia Poisoning

Ammonia is produced by the betta’s biological waste. Bettas can put up with ammonia poisoning more than other fish, but it’s still poisonous to them. Ammonia poisoning in betta fish is difficult to distinguish and it can kill them if you don’t catch it on time.

Ammonia poisoning can happen when you set up a new tank or add too many fish in a tank. Check if the gills of your betta is burning or if it’s swimming in darting movements. If this is the case, you need to clean your fish tank and replace it with dechlorinated water.

Swim Bladder Disease

If your betta fish is at the bottom and is floating upside down, swim bladder disease is likely to be the case. In a rare case, it can become fatal but swim bladder disease can easily be curable by letting your betta fast for a few days or at least 3 days. It may seem like a long fast for you, but betta fish can go on for more days without food.

Aside from a change in diet, check whether it’s caused by bacterial infection by looking at the colors of their scales.

Constipation

How much do you feed your betta and what kind of food do you give them? Betta fish have a short digestive tract so constipation can easily happen.

If your betta is laying at the bottom of the tank and looks to have a bloated stomach, it’s possible that they are constipated. Overfeeding or having insufficient fiber in their diet can lead to constipation. Adjust their diet and let them fast for 2-3 days and see if they will poop during the fast.

Pregnant

If the belly of your female betta fish is bulging and has a round white patch, it could be because they are pregnant. You may also see your male betta fish may also start building bubble nests to fertilize the eggs.

Move your female betta to a breeding tank so she can have her privacy and is not bothered by other swimming fish.

Old Age

The average lifespan of a betta is 3 years but some can live up to 4 to 5 years if they have the perfect habitat and are well-taken care of. If you know the age of your betta when you bought it from a breeder, then it’s easy to tell whether they are on their senior stage.

Older betta fish may love to hug the bottom of the tank or even the sides. The color of old betta fish will fade and white dots may also show in time. Loss of vision, decrease in appetite, and frequent naps are also signs that your betta is near the end of their life span.

Sleeping or Resting

Some betta fish may prefer sleeping at the bottom of the tank because of the filter current above the tank. Bettas will take quick naps during the day. Just check if they are back to normal in a few minutes so you don’t disturb its peaceful snooze.

Boredom

If there is nothing to do in the tank, they might as well be still at the bottom of the tank. Add decorations, gravel, some plants, or have a change of scenery to keep them entertained. You can also buy dedicated toys for betta fish like ping-pong balls.

It’s Dead

Sadly, betta fish can die suddenly if signs of illness aren’t visible or were addressed late. You will see your betta laying at the bottom of the aquarium if it’s dead. When this happens, clean your aquarium well and remove any rotten remains to avoid causing problems to any of its tank mates.

Your betta’s color is clear and bright – A healthy betta fish has vibrant colors and smooth scales.

Your betta loves to engage with you – Betta fish know you as their guardians and may even be excited and swim around when you come near its tank.

How to make sure that your betta is happy and healthy

Ensuring the happiness of your betta fish is necessary not only for the betta but for you, as a pet owner. Knowing that your betta feels safe with you is a good sign of great companionship.

To keep them healthy is to keep them happy.

We’ve listed the things you can do to ensure that they have the best life you can give.

Create a great habitat

Keeping your betta fish happy means it has all it needs in its home. Coming from Southeast Asia, betta fish live in warm water with lots of plants and low water flow.

A 5-gallon size of the tank is the most recommended to keep them active and encourage them to swim around and play. Having plenty of space with plants and semi-soft substrates will also keep them happy.

Another way is to add little caves or suction cups for them to hide and play and use as a resting place.

Keep the water clean

It’s crucial that your betta’s water is clean and safe. As mentioned, they do like warmer water with around 74°F to 79°F.

Check if pH level is around 7.0 and ensure that the water doesn’t have any nitrite or ammonia present.

Any chemical buildups may hurt your betta, clean your fish tank regularly and always check the temperature to make sure that your betta is living in a safe place.

Feed them properly

The good old pellets and flakes may be fine, but having some treats will make them happy. Betta fish love lives bloodworms, brine shrimps, and daphnia.

Bettas need food rich in protein and while flakes are fine to use, they don’t have enough nutrients found in meat.

Do not overfeed your betta fish as they are at risk for constipation or swim bladder disease. If you notice your betta fish has a bloated belly, try to feed it with a de-shelled and diced pea.

Give them toys

A good way to keep your betta happy and entertain is to give them toys to play with. Betta fish likes to push things around so ping-pong balls or betta balls are quite popular.

Laser pointers are also good for both of you to have a little bonding time. Like cats, they are curious and will follow the pointer which can also help them exercise.

Check if they do or don’t want a tank mate

Bettas are territorial and can be aggressive, especially the wild ones. While you may think that your single betta is lonely, your betta fish can thrive by itself. Try not to apply human emotions as some bettas have different concerns.

But, do not push out the idea of getting it a tank mate as it’s possible that they do want one. Male bettas are aggressive to other male bettas so you can opt for another type of fish instead.

Consider going for guppies, African dwarf frogs, and cory catfish. Monitor any interactions and provide caves and plants as hiding places. Remove the tank mates the moment you see conflicts as it may be stressful for both of them.

Watch for any signs of illness

Make sure you learn and know how to figure out when your fish is experiencing discomfort that we’ve also covered above so you can fix it as soon as you can.
