You sit back and watch them swim around, admiring their gracefulness… when suddenly, one of them starts darting and dashing around the tank wildly!
Now you’re wondering – why is my discus fry darting and dashing, and is there anything I can do about it? First of all, don’t panic!
Every problem has a solution, so let’s take a look at some of the possible reasons why your discus dashing and darting, and what you can do about it.
What Are the Symptoms Discus Darting?
To start with, it’s important to identify the symptoms of darting. This can help you figure out what’s causing the problem and how to solve it.
Here are some signs tell your discus fry is darting:
- Loss of appetite
- Clamped fins
- Discus fish swimming straight up and down
- Swimming strongly towards the walls
- Swimming quickly around the tank
- Discus jumping out of the tank
Why Are My Discus Dashing & Darting?
Improper Water Conditions
Sometimes you can get deceived by the fact that your discus fish are robust and able to withstand a lot of abuse.
However, they are still very sensitive creatures, and if the water conditions in their tank are not ideal, it can stress them.
This can lead to them darting and dashing around the tank as they try to escape the stressful situation.
Ammonia Concentration & Nitrite Levels
These toxins can build up for a number of reasons, such as overfeeding, too many fish in the tank, or not cleaning the tank regularly enough.
If you don’t provide a refuge for your discus, it will become stressed and start zipping around the tank trying to escape.
Sudden Change in the pH Level
In fact, a rapid shift in pH levels is one of the most harmful things discus fry can encounter in a fish tank.
While they may be able to adapt to slowly changing pH levels over time, a sudden change can cause them to feel disoriented and stressed.
In an attempt to feel better, your discus fry will start darting and dashing around the tank like they are looking for a way out or trying to find something they’ve lost!
Wrong Water Temperature
Discus fry needs warm waters similar to their natural habitat in the Amazon basin.
When the temperature falls below 82°F (28°C), they will start looking for somewhere warmer to swim.
If there’s nowhere for them to go, they will become anxious and start darting and dashing around the tank in an effort to raise their body temperature.
Similarly, if there is a sudden change in water temperature, it can also shock your discus fry and cause them to start swimming erratically.
Parasites can attach themselves to your fish in several ways, such as by sucking its blood or attaching to the body or digestive system. These parasites might be worms, protozoa, or other organisms.
Consequently, your fish will feel irritated and itchy. They will start trying to scratch themselves on the gravel or decorations in the tank to get rid of the parasites.
When your discus fry doesn’t have the space to swim around and feel comfortable in their tank, it will cause them a great deal of stress.
They will start to push other species around, causing fights and making everyone in the tank feel uncomfortable. Thus, your fish will start darting around as they try to find some peace and quiet!
In addition, too much fish means too much waste in the tank, which can lead to ammonia and nitrite buildup, further making the problem worse.
Aggressive Tank Mates
Imagine living in a place where you always get bullied and pushed around. It would be pretty stressful, right?
Well, that’s exactly how your discus fry feel when they are living with aggressive tank mates.
Discus fish are relatively peaceful creatures, so they don’t do well with bullies in the tank. This bullying can manifest in nipping at the fins or tails, chasing, or simply not letting them have their share of food.
In this case, it will make your discus fry anxious and stressed, causing them to start darting and dashing around the tank in an effort to get away from their bullies.
I think we all know the feeling of being triggered by something we ate. It doesn’t feel good, right?
Well, the same goes for your discus fry. If they are not getting the right diet, it can lead to all sorts of problems, such as malnutrition, indigestion, and even organ damage.
If your discus fry is not receiving the proper nutrients, it will become weak and sick. This often manifests in erratic swimming as they attempt to find a solution on their own!
Like any other fish, discus fry is very sensitive to sound. In fact, loud noises can be even more harmful to them than sudden changes in water temperature or pH levels.
This is often seen in tanks that are located near a TV or stereo system. Even if the volume is not turned up too loud, the vibrations can still be enough to stress out your fish!
As a result, they will start searching for a quiet place to hide, or just hitting the glass to try to get away from this loud and stressful environment.
Sudden Lights Changes
Discus fry is used to living in murky waters, so they are not used to sudden changes in light.
For example, if you turn on the lights in the room too suddenly, it can startle your fish and cause them to dash around with anxiety.
The same goes for any sudden changes in lighting, such as from a power outage or a flash of lightning. These sudden changes can be very stressful for your fish, causing them to feel disoriented and lost.
What Should I Do If My Discus Darting & Dashing?
Do Frequent Water Changes
There is a great chance that your discus fry is experiencing stress due to the water quality in their tank.
Therefore, make sure to do a water change of at least 20-25% once a week to keep the water fresh and clean. This will reduce the stress on your fish and make them feel more comfortable.
Treat Ammonia in Your Tank
If the levels are high, you can do a water change to bring them down. Also, you can add an ammonia remover to your tank to help get rid of the ammonia more quickly.
To control ammonia levels in the future, you can install an aquarium filter with an ammonia-removing pad.
Add Suitable Tank Mates
If you think that the problem might be due to aggressive tank mates, you can try adding some more peaceful fish to the tank.
Adjust pH Level & Water Temperature
As I mentioned before, sudden changes in pH levels and water temperature can be extremely stressful for your discus fry.
The ideal range for discus fry is between 6.0-7.0 for pH levels and 82-86 degrees Fahrenheit for water temperature.
To keep the pH levels stable, you can use a pH buffer in your tank. As for the water temperature, you can use an aquarium heater to keep the water at a consistent temperature.
Sometimes you might think that you are feeding your discus enough when in reality you are overfeeding them.
For discus fry, it is best to feed them 2-3 times a day with only as much food as they can eat in 2 minutes.
If you are still not sure how much to feed them, you can always consult with your local fish store or veterinarian. They will be able to give you more specific advice on how to properly feed your fish.
Maintain Stable Lighting
Last but not least, adequate lighting is crucial for the health and well-being of your discus fry.
To avoid any sudden changes in lighting, you should use an aquarium hood with a timer. This way, the lights will turn on and off at the same time every day and your fish will get used to the light schedule.
