Are you concerned about your stressed betta fish? If your Betta has started acting oddly or refusing food, or has developed horizontal “stress stripes” along the length of his body, then it is time for you to act. Luckily, most stress behaviors in fish are a result of something tangible that you can change. Consider these five ways to help your fish friend:
Check your water parameters.
Fish in water with unhealthy levels of ammonia, nitrate, or nitrite can quickly become unhealthy. Acting stressed is the first sign of water quality issues. If in doubt, swap it out – but remember that frequent partial water changes of about 20% are better than infrequent large water changes. You can bring a sample to your local pet store and have them check it for you. If you want to do it yourself, consider the API Master Test Kit, available for about $20. This test kit will also let you check your Ph levels, which should be 7.0 for a happy betta.
Use water conditioner drops.
Do not use untreated tap water for your tank. It has trace amounts of chlorine and other minerals that can cause your fish to stress. Water conditioners are cheap and readily available at your local fish store or online. Some formulas have added aloe vera, which can improve the natural slime coat your fish has and help to reduce stress.
Check your water temperature.
Many people buy a betta under the mistaken impression that they require no special equipment. However, bettas are tropical fish and will become stressed in standard room temperature water. Ideally, your betta should have a heater that keeps the water between 76 and 80 degrees. When the water is too cold, your betta will be stressed and more likely to contract diseases.
Create hiding places.
The betta’s natural environment is much darker and filled with much more vegetation than the average fish tank. Adding some plants or decorations with hiding spaces will make your betta fish feel more secure. Try putting a small unglazed terra cotta pot on its side to make a cheap and effective cave.
Use tannins.
Another option to help your betta feel less exposed is to introduce tannins in the water. Tannins are the natural compound that gives tea its brown color. You can use either aquarium safe woods or Indian almond leaves in your tank, as they both naturally release tannins. This darkening of the water will mimic your betta’s natural environment, which will make him feel less exposed and less stressed.
We know you want the best for your Stressed Betta fish, and that means making sure he is as healthy as possible. Stressed fish are more prone to diseases like fin rot, Ich, and swim bladder disease. The better you can make his water quality and the more you can mimic his natural environment, the healthier and happier he will be. It takes a small amount of effort but the increase in coloration, personality, and activity that you’ll see will be thoroughly worth it.
Having a stressed betta fish is never good. And if you feel like your betta is stressed then you’ve come to the right article. Soon you’ll find out the dangers of stress in bettas, as well as the symptoms, causes, and treatments!
What Is Stress?
Stress in fish is similar to stress in humans. It’s where a circumstance causes your betta to release cortisol (A stress hormone) and adrenaline into your bettas system.
As you know already these two hormones are harmful to animals and over time will begin to damage your betta in a number of different ways.
You should also be aware that there are different types of stress.
Low/Long Term Stress
Low or long term stress is stress that is minimal, however, occurs constantly. In a low, long term stress environment your betta will be constantly trying to adapt. This will weaken his immune system and health which slowly begin to deteriorate.
If a betta is stressed for long amounts of time it will exhaust itself until death.
High/Short Term Stress
Another type of stress is high short term stress. This is the stress that is going to occur very rapidly, however, it’s not constant. The effects of high short term stress are only going to last for a few days.
However, repeated exposure to this type of stress is still bad for your betta.
What Stresses A Betta Fish?
There is a range of different causes of stress in betta fish. Being able to spot the causes and address them correctly is one of the ways you’re going to keep your betta happy and healthy!
Common Low/Long Term Stress Causes
Here are the most common low/long term stress causes that are likely to affect your betta. Luckily they’re also largely within your control.
A Tank That Is Too Small
When you’re picking a house for your betta you should never house him in anything smaller than 5 gallons. When a tank is smaller than 5 gallons it will become dirty very quickly which will stress your betta out.
Not only that, but he will also become bored with his surroundings which will result in frustration or even depression. (Believe it or not, bettas can suffer from this too, find out more.)
So if your tank is smaller than 5 gallons then you should look into buying a bigger one ASAP. Here are some of the best 5-gallon tanks on the market right now, but remember, there’s no harm in going bigger than 5 gallons either!
Overcrowding
Just like if a tank is too small, if a tank is too overcrowded the conditions are going to be too poor for your betta to survive. If you’re not sure how many fish you should add to a tank, the general rule is 1 inch of fish per gallon of water.
However, take the rule with a pinch of salt, and research thoroughly the recommended tank size for any fish you plan on adding with your betta.

Incorrect Conditions
If your tank isn’t overcrowded and it’s large enough the conditions may still not be correct. You should also make sure that the pH of the tank is correct (Check out the best pH level for bettas) and that the temperature is correct as well. You may see bettas in cups in pet stores, but this isn’t right and if they’re left in these conditions they’ll die quickly.
Making sure the conditions are right isn’t just important for your betta, but it’s also important for any other living creature in the tank as well. And in the wrong conditions, an increase in harmful bacteria, parasites, and algae is likely to happen.
You’ll also need to make sure that the water isn’t too hard or soft for your betta (this normally determines the pH of the water)

A Lack Of Hiding Places
Because your betta is a solitary fish, it’s important to give him some hiding places where he can relax. If your betta never has any downtime and always feels like he’s on edge then it’s going to slowly stress him out. That’s why it’s so important to decorate your tank in a way that makes him feel safe.
And this can even occur when he’s in a tank alone. Betta’s will always think there’s a risk of a predator trying to attack them, so by giving them places to hide you’re going to alleviate some stress.
Short/High Term Stress
It’s not just long term stress that is going to be detrimental to your bettas health. There are also many different causes of short, high term stress that will damage your betta too. Here are some of the most common.
Bullies/Aggressive Tank Mates
Aggressive tank mates that might bully your betta are going to be short/high term causes of stress, however, if left over time they can also cause long term stress. It’s hard to think that another fish in your tank will bully your betta, but they can.
Unfortunately bettas aren’t fast swimmers, so fish that are fin nippers may take a bite before swimming off rapidly. Not only is this going to stress your betta out it’s also going to increase his chances of suffering from fin rot, a disease which can become fatal if left untreated.
The problem with aggressive tank mates is there’s no way they can be escaped. In the wild, if a fish is acting aggressive, your betta can choose to either swim away or fight. In a tank, there’s no where he can swim too.
Sudden Changes To The Water Conditions
You should also be aware of sudden changes in the water conditions. Slowly deteriorating water causes low stress, but when the water shifts quickly it can often shock your betta, or stress him so much he’ll die.
There are a number of different causes that can change the water conditions in your tank. You may have introduced something into the aquarium on purpose (such as a new decoration) or by accident (accidentally spraying chemicals into the water). Whichever it is, you’ll need to act quickly to sort the situation out.
As well as introducing an agent of change, sometimes it’s beyond your control completely. For example, if your heater breaks then then this could cause a sudden change in the water conditions (Especially in 5 gallon tanks, which lose heat quickly. Check out some of the best heaters for 5 gallon tanks, as well as what to do if your heater breaks and you don’t have a spare.)
Illness
Another cause of high/short term stress are illnesses which can either be parasitical, bacterial or fungal in nature. Illnesses are going to be short in nature, and if left untreated they will often become fatal to your betta.
There’s a whole range of different illnesses and diseases that can affect your betta so it’s well worth your time reading up on them. Here are some of the more common illnesses and diseases bettas can suffer from.
What Are The Symptoms Of A Stressed Betta Fish?
The symptoms of stress in bettas are vast, and some of them may also be natural behavior. That’s why you should get to know your betta and how he acts, so you can realise when there’s something stressing him out. Here are the most common symptoms of stress in betta fish.
He Just Seems Off
One of the first signs of a stressed betta is that they just seem off. Maybe they aren’t swimming as much as they used to before. Or perhaps they’re not personality is different. Whatever it is, he just won’t be the same.
Spotting this early is one of the best ways to remove the cause of stress before it gets worse.
Lack Of Appetite
Another sign is a lack of appetite. When your betta loses his appetite you know there’s something wrong. they’re incredibly gutty so it takes a lot to put them off their food.
However, don’t take a lack of appetite as a sign they are stressed alone. It often means a lot of things including your betta may be sick, constipated or perhaps even depressed.
If you’re trying to diagnose stress in your betta then a lack of appetite should be an accompanying symptom.
More Prone To Disease
If your betta has become sick then it’s probably because he’s stressed. A lot of people think that disease causes stress when actually stress causes disease. Stress will weaken your bettas immune system making them more prone to infection.
So if you notice your betta has become sick then as well as treating the sickness, you should also look for what’s causing your betta to be stressed in the first place, such as poor water conditions, aggressive tank mates etc.
Skittish Swimming Behavior
It’s normal for your betta to dart around the tank every once and a while. But if you notice your betta constantly darting around or any other skittish swimming behavior then you should figure out the cause behind it.
Most likely it will be because he’s scared of other tank mates, but it could also be something in the tank or outside the tank that’s putting him on edge.
As well as skittish swimming behavior you may also notice him: rubbing and crashing into rocks, clamping his fins, darting to the bottom of the tank, and rubbing against the gravel.
Hiding
Another sign of stress is hiding. Every once in a while your betta will hide away and that’s fine. However, if you notice him spending most of his time hiding away rather than swimming then there’s something wrong.
You’ll need to figure out whether the fact he’s hiding is because of bullying, or because of some threat he sees (even if you realise it isn’t a threat).
Change In Color
You may also notice a change in the color of your betta. Instead of being his usual vibrant and colorful self, your betta may begin to become duller.
He’ll look a lot paler and won’t catch your eye as much when he’s swimming around. As well as this you may also notice stripes along his skin that are a different color. These are commonly referred to as stress stripes.
However, a loss of color can also occur when your betta is depressed, and in rarer cases, when he’s suffering from hole in the head.

How To Help A Stressed Betta Fish
Now that you know some of the most common causes of stress in betta fish and what the symptoms are, you’re going to want to know how to treat them effectively as well!
Remember, it’s important that you figure out the cause of the stress ASAP and address it straight away. Here are some of the most common ways you can treat stressed bettas.
Frequent Water Changes
Obviously water changes are going to stress your betta a little bit. But not changing the water is going to stress him out a lot more.
You should perform water changes once every week or two weeks depending on the size of the tank. This is going to reduce the amount of ammonia and nitrates in the tank, making it more hospitable for your betta.
The cleaner environment is going to stop your betta suffering from long term stress.
Use A Strong Filter
Going hand in hand with frequent water change is having a strong filter. Filter’s act as a way to keep your tank water clean when you’re not around to do it.
They are a lot less invasive than performing water changes, which is why they’re so good at keeping your betta stress free!
Just make sure that your filter isn’t going to produce a current, or your betta won’t like it.
Checking The Temperature
As well as making sure the water is clean, you also need to make sure the temperature is staying constant. Depending on the size of your tank, where it’s placed in your house, etc the temperature may be fluctuating.
Fluctuation in temperature is one of the things that will really stress your betta out. In fact, when the temperature drops too quickly and too low, it can even shock your bettas system so much that he’ll die.
Remove Any Aggressive Fish
Your betta is already aggressive so the last thing you need is to add him with other aggressive fish. If you notice a fish being consistently aggressive towards your betta then you’ll need to remove them from the tank.
Even if your betta is fighting back he’s still going to be stressed out.
Likewise, if you notice your betta constantly attacking other fish then to stop all the fish from stressing you should move him to another tank.
A Lot Of Hiding Places
One of the best things you can do to stop your betta from being stressed is to provide him with a lot of hiding spaces. Hiding spaces are vital a helping keeping your betta relaxed.
They provide him with places where he can rest without fear of being attacked and also make him feel safe if he’s beginning to feel stressed.
Some good hiding places are plants and caves as well as various decorations.
Provide High-Quality Food
If you’re giving your betta food which isn’t high-quality then his immune system is going to suffer. And a weakened immune system is obviously going to stress him out.
When choosing high-quality food you should have a mix of high-quality betta pellets, as well as live and frozen food!
Give Your Betta Enough Space
Your betta is going to need a minimum of 5 gallons to be happy and stress free. However, bigger is always betta. You may have heard that bettas can survive in small tanks even 2.5 gallons in size. And this is true. However, survive and live happily are two different things.
If you want your betta to be happy and stress free then stick to at least a 5 gallon tank.
(These are the best 5 gallon tanks you can purchase for your betta. My personal favourite is the Fluval Spec V 5 Gallon.)
Conclusion
In conclusion, if you’re treating your betta right and providing him with the necessary care, then the chances of him becoming stressed are low.
If you do notice your betta appears stressed then you should act immediately to fix whatever the problem is. When you do that, your betta will live a long life.
