Why Is My Betta Fish Hanging Vertically?

There are a few likely possibilities as to why your betta fish may be floating upside down. When you notice your fish in this position, you will need to take action right away. Here are some of the main reasons why it happens:

Poor Water Conditions

The most common cause of vertical death hang in bettas is poor water conditions. In many cases, these conditions can lead to an infection in the betta fish’s swim bladder, as well as many other illnesses which will result in your betta not being able to swim properly.

A Small Tank

Betta fish need to be in the right size of tank to be healthy and thrive. Your fish needs a big enough tank for proper living conditions so it can grow and have daily activity. A small tank or bowl could be the reason behind your betta fish’s vertical death hang.

If your unsure which size tank you should get for your betta it should be 5 gallons minimum. However, bigger is always better! (Find out more about the minimum tank size for bettas.)

Temperature Problems

Betta fish need a nice and warm living condition to stay healthy. If the water is too cold or too hot, then it could result in your betta becoming sick, which in turn could cause a vertical death hang. Make sure that you’re keeping the water in your tank between 76-80F however ideally at 78F.

Too Much Food

Often a betta fish will float upside down as a result of overeating. Remember your bettas natural diet consists of insects and larvae, which have a higher moisture content. Your betta is probably being fed a lot more pellet food which is going to be drier and bloat up inside them.

This swelling can cause blockage, which leads to pressure on the swim bladder, as well as constipation. This of course can cause swimming troubles in your betta!

Poor Diet

On the subject of too much food, a poor diet can also cause vertical death hang in your betta. You may have heard that feeding your betta bloodworms is good for them, however, a lot of time this isn’t the case. In fact if you’re feeding your betta fatty foods like bloodworms, or fish flakes meant for omnivores, it’s going to damage them!

Low pH Level

Another reason your betta fish may be floating upside down is that the pH level of the water is too low. The ideal range is between 6.8 and 7.5. In some cases, betta fish can thrive in slightly more acidic water. However, they do not do well in water with a low pH level.

The General Health Of Your Betta

As you can guess all of these things are going to affect the general health of your betta. And once your betta succumbs to certain diseases, then a vertical death hang is imminent.

Once you determine why your fish is hanging vertically, you can begin treatment to get them healthy again! Getting them the help they need in time could potentially save their life.

Give Them Medicine

The first thing you should do is make sure that you’re giving your betta the medicine they need, if it’s due to sickness. The most common sicknesses that cause vertical death hang are constipation, swim bladder disease, and dropsy.

Give Them Daphnia

As well as this, you can also try feeding your betta daphnia if you think they’re constipated or suffering from swim bladder disease due to constipation. Feeding them daphnia will fill their bellies with high quality fibre which will help them pass any stool.

Try API Stress Coat

If there’s one water conditioner I love, it’s API Stress Coat. If you haven’t tried it yet I’d highly recommend it. It has aloe vera in it which reduces your bettas stress levels, and can help them feel better again!

How To Prevent Vertical Death Hang In The Future

Now you know all the ways to treat vertical death hang in your betta, then here are the best ways you can prevent it from happening in the future!

Keep The Water Clean

Your betta fish needs clean water to live in. Just by living your betta produces a lot of waste which will eventually turn to ammonia in the tank, which leads to poor water conditions.

In these conditions your betta will begin to get sick, which is why it’s so vital to make sure that you’re testing the water regularly, performing frequent water changes, and using a high quality filter!

Get the Right Size of Tank

Just because betta fish are small doesn’t mean they can live in a small tank. All betta fish need a tank that is at least 5 gallons (19 liters). However, bigger is always better when it comes to keeping fish, so you should always try to go as big as possible!

Proper Feeding Portions

Overfeeding is one of the biggest causes vertical death hang in betta fish as it often leads to swelling. To prevent this, you need to stick to proper feeding portions and only feed them 1 – 2 pellets of food 1-2 times a day.

For pellets, you should soak them first to allow moisture into the food. This makes it easier for the betta fish to digest safely without any swelling. To do this, you should soak the pellets in some tank water for at least 10 minutes before feeding them to the fish.
