Sharing is caring!

Did you walk by your aquarium today and notice that one of your beloved ghost shrimp had suddenly passed away? If so, you may be feeling confused and frustrated about what could have possibly caused this unexpected death.

There are many possible culprits when it comes to why your ghost shrimp might have died. Some common causes include poor water quality and overcrowding in the tank, as well as parasites and infections that can easily be transmitted from shrimp to shrimp.

In this article, I’ll take a closer look at why ghost shrimp might die, and offer some tips on how you can help prevent this from happening in the future. Read on to learn more!

Why Do My Ghost Shrimp Keep Dying?

Wrong Water Parameters

Water parameters act as the foundation of a healthy shrimp tank, so if the right water conditions are off, it can lead to a number of problems for your ghost shrimp. Some common issues include high levels of ammonia, nitrite, and pH, which can all be damaging to the health and well-being of your shrimp.

Also, any sudden changes in water temperature, salinity levels, or lighting conditions can shock these guys leading to losing their balance and dying.

For example, you did your weekly water change and suddenly noticed your shrimp acting strangely, lying at the bottom of the tank or floating up to the surface. This is a clear sign that something has gone wrong, and you should take action right away to get your shrimp back on track.

Before you start to solve the problem, you should know first the exact water parameters you need to keep your ghost shrimp healthy and thriving. Here are some things to look out for:

  • Temperature: 65 – 75 degrees Fahrenheit (18.3 degrees to 23.8 degrees Celsius)
  • General Hardness (GH): 3 – 10 dGH
  • Carbonate Hardness (KH): 3 – 15 dKH
  • Nitrate Level: Below 20 ppm
  • Ammonia and Nitrite: 0

Next, consider doing regular water testing to make sure that your shrimp are getting the right conditions. This can include investing in a good test kit, or if you have access to a local aquarium store, asking for help with testing your water parameters.

Also, you should use an aquarium thermometer and hydrometer to monitor your tank temperature and water levels, respectively. Plus, if you live in a region with low water quality or high levels of heavy metals, you should use a water purifier to help keep your shrimp safe and healthy.

Poor Maintenance & Incomplete Cycling

Unfortunately, many aquarists are not aware of the importance of basic tank maintenance, which can lead to a number of problems down the line.

One common mistake is incomplete cycling or allowing your aquarium to go through the nitrogen cycle without testing and adjusting water parameters accordingly. This can cause high levels of ammonia and nitrites in your tank, which can be deadly for your ghost shrimp.

To avoid this, you should make sure to complete the cycling process and keep a close eye on any changes in water quality. Additionally, you should do regular maintenance tasks such as cleaning filters and replacing filter media, vacuuming gravel or sand, and removing debris from the tank.

To cycle your tank, you can add ammonia to the water in small amounts, and then test for nitrites and nitrates over the course of a few weeks. This will help establish beneficial bacteria colonies that feed on the ammonia and break it down into more harmless byproducts.

Excessive Water Changes

While regular water changes are important for maintaining healthy water parameters, you can also run into problems if you overdo it. Ghost shrimp are sensitive to sudden fluctuations in the quality of their environment, and too many major water changes can lead to discomfort or death.

When doing routine water changes, you should aim to keep the frequency of your changes and the amount of water you remove consistent. For example, try doing a 20-30% water change every 2 weeks or so, and make sure not to remove more than 50% of the tank’s water at any given time.

Then, slowly acclimate your shrimp back into the tank by floating them in a small container of water out of the tank, and slowly releasing them once they start to move around.

If you do notice any signs that your ghost shrimp are struggling, such as lethargy, loss of appetite, discoloration, or rapid breathing, double-check your water parameters. If you notice any significant changes, you should take action right away to save your shrimp.

You Put Them in a Saltwater Aquarium

Shrimps are freshwater creatures by nature, and putting a ghost shrimp into a saltwater tank may seem harmless. However, this can lead to serious complications down the road.

Saltwater aquariums tend to have higher pH levels and different water chemistry than freshwater tanks, which can cause stress or shock in your shrimp. Plus, the increased salinity in the water can make it difficult for your shrimp to breathe, leading to respiratory distress and death.

To avoid this, it’s best to keep your ghost shrimp in a freshwater tank with regular water testing and maintenance. And if you do need to move them into a saltwater tank for any reason, be sure to slowly acclimate them as described above, and closely monitor their behavior for signs of stress.

Further, you should know that saltwater tanks have to be a temporary option for ghost shrimp, as they aren’t meant to live in this environment for long periods of time. So if you need to put them in a saltwater tank, transition them back into a freshwater aquarium as soon as possible.

You’re Using Tap Water

Using municipal tap water in your aquarium might seem like a convenient option, but it can be extremely harmful to your ghost shrimp.

Since tap water tends to have high levels of impurities and chemicals, such as chlorine and chloramines, this can cause serious health problems for your shrimp. And even if you use a water conditioner to remove these chemicals beforehand, the water can still contain trace amounts of chloramine.

To avoid this, you should treat tap water with an aquarium-safe de-chlorinator to remove these harmful chemicals. Then, you should use a water testing kit to check the pH and salinity of your treated water and make sure that it’s within the appropriate range for ghost shrimp.

In addition, you can install a water filter or UV sterilizer in your fish tank to remove any impurities and prevent them from building up over time. I recommend using a 3 stage filter that combines mechanical, biological, and chemical filtration to keep your water clean and healthy.

Excessive Amount of Copper in Your Aquarium

Copper is toxic to many fish and invertebrates, including ghost shrimp, as it can damage their gills and interfere with vital processes like breathing and reproduction. Your tank can get copper through copper-based medications, tap water, aquatic plant fertilizers, and even some types of fish food.

To avoid this, you should regularly check that your tank water does not have high levels of copper. This can be done with a copper test kit or by consulting the test results of your local fish store.

In addition, you should avoid using any copper-based medications in your shrimp tank. Instead, you should opt for natural remedies that have proven safe for shrimp and other aquatic creatures.

Further, you should read the labels of any fish food, plant fertilizers, or other products that you add to your tank carefully to make sure they don’t contain copper.

Wrong Medication

Sometimes you think you’re helping your aquatic friends, but it turns out you’re actually harming them. If you use too much medication or the wrong type of medication in your shrimp tank, this can lead to a whole host of problems.

For example, using medications that contain copper can damage their gills and interfere with important processes like breathing and reproduction. Also, improperly dosed medications can cause stress, shock, and even death in your shrimp.

To avoid this, you need first to quarantine any new shrimp that you add to your tank. This will allow you to monitor them for signs of illness and check if they’re sensitive or allergic to the medications that you use.

Then, when treating sick shrimp, it’s important to only use high-quality medications specifically designed for aquatic creatures like ghost shrimp. And be sure to dose them exactly according to the instructions on the label, as this will help reduce any adverse effects.

Malfunctioning of Aquarium Equipment

Aquarium equipment isn’t foolproof, and sometimes it can malfunction or break down. If this happens, it may not be immediately obvious to you why your ghost shrimp are dying.

For example, a power outage could cause the filter to stop working, which in turn would allow impurities to build up in your tank water. Or the pump might become clogged and start sucking your shrimp up into the filter, leading to their deaths.

For this reason, you should regularly check that all of your equipment is functioning properly and replace any parts or filters as needed.

Additionally, it can be a good idea to invest in backup power supplies for your tank, such as a battery-powered pump, in case of an emergency.

Poor Diet

When it comes to food, there are three things to keep in mind. You can kill your shrimp by feeding them too much, or not enough, or by giving them a diet that lacks the nutrients they need.

For example, if you overfeed your shrimp, their food will start to decay and release harmful toxins into the water. On the other hand, if you feed them too little or give them an unhealthy diet, they will not be getting enough nutrients and vitamins that are essential for growth, development, and overall health.

Also, low nutrients in their diet can impact their ability to fight off diseases and parasites. So you should always be sure to feed your shrimp a nutritious, well-balanced diet that is tailored specifically to their needs. Some good options for shrimp food include:

  • Zucchini
  • Algae wafers
  • Soft vegetables
  • Pellets or other sinking food items

Furthermore, ensure you provide them with a single meal each day consisting of food they can eat within 20 minutes. However, if you fear you overfed your ghost shrimp, don’t fret. Just withhold their food for a couple of days.


Can you imagine living in a confined space with hundreds, or even thousands, of other people? Of course, this would be completely overwhelming! Well, the same can be true for shrimp living in a tank.

Overcrowding your shrimp in tanks can create an unhealthy, stressful environment that can lead to poor growth and development, infection, and even death. This problem rises if you’re not providing them with adequate space to swim freely or hiding places where they can escape any competition.

So if you notice your shrimp are dying off more frequently than usual, it may be a sign that you need to expand their tank. For the best results, try to provide each shrimp with at least a tank size of 10 gallons or more for multiple ghost shrimp.

Also, you can add some plants or hiding places to give them the space they need to thrive. Some good options include:

However, be careful not to add too many decorations or items to your tank, as this can have a negative impact on water quality by increasing the risk of toxins, debris, and bacteria building up. In addition, avoid any sharp or rough items in your tank, as these can cause injury and stress to your shrimp.

Wrong Tankmates

Why Did My Ghost Shrimp Die

Do you remember your mid-school science classes and the lessons on ecosystem interactions? Well, this same concept applies to your tank. If you’re keeping ghost shrimp along with other types of fish or invertebrates, there’s a good chance that it could be harming them.

For example, some common tankmates – such as large cichlids, bettas, or aggressive fish – are notorious for preying on ghost shrimp. Not only is this bad news for your shrimp, but it can also lead to a buildup of harmful ammonia in your tank due to their decaying corpses.

Here are the tankmates you should avoid while setting up your tank:

On the other hand, there are some fish species that would make great tankmates, such as:

Acclimation Issues

If you have recently got a new ghost shrimp, you should be aware that it may take some time for your shrimp to acclimatize to its tank. Otherwise, it could be a contributing factor to why your ghost shrimp are dying.

For this purpose, you should make sure to slowly acclimate your shrimp to its new tank. You can do this by floating the bag they came in outside of the tank for 15-30 minutes. Then add a few tablespoons of tank water every 5-10 minutes until the bag is about halfway full.

After that, you can add the shrimp to your tank and monitor them closely to ensure they are adjusting well. Another way to acclimate your new shrimp is the drip method, which involves adding a small amount of tank water to the bag every few minutes.

Then, once the bag is about halfway full, you can use a siphon to slowly release the shrimp into your tank. When you’re ready to add them to their new home, be sure to keep an eye on them and provide them with plenty of hiding places, such as rocks and plants.

Molting Process Issues

Did you know that Ghost shrimp frequently molt, or shed their exoskeleton? They’ll replace it will a new one eventually, sometimes sooner than later. But what happens when a Ghost shrimp doesn’t escape its old shell in time?

The shrimp becomes trapped and people refer to this as the white ring of death because there’s a visible white band where the head meets the body. As they get trapped, the molting shrimp can’t absorb oxygen from the water, which leads to suffocation and, eventually, death.

To avoid this, you should always be on the lookout for any signs of molting and ensure that your shrimp has a safe place to molt in peace. This can include adding some extra plants or decorations in the tank, or even leaving parts of the tank bare so they have room to move around.

Also, they need a high-quality diet, clean water, and a stress-free environment to ensure that they molt successfully and don’t experience any issues. And, above all else, you should avoid disturbing them or removing them from their tank while they are molting.

Improper Male to Female Ratio

Male shrimps can be quite aggressive towards their female counterparts, especially when there are no females present to distract them.

This is why you should have a balanced male-to-female ratio in your tank, as too many males could decrease their lifespan dramatically.

Ideally, you should aim for three female shrimps per male shrimp. This will keep the males busy and less likely to attack or bother their female counterparts.

And, of course, you should make sure that your shrimp are at least roughly the same size, as this can help avoid any dominance issues or fights.

Should I Get Rid of Dead Ghost Shrimp?

Of course, you should never simply ignore the death of your shrimp and assume that they will decompose on their own. If you leave dead shrimp, it can lead to ammonia buildup and other issues that can be detrimental to not only your shrimp but also the other tank inhabitants.

However, aquarists debate whether or not you should intervene if living shrimp in your tank are already eating dead shrimp. Some would say to let nature take its course, but others believe that it’s best to remove the carcass before it begins to rot and pollute the shrimp aquarium.

Anyway, if your living ghost shrimp haven’t shown any interest in the dead one, or they started eating it but then stopped and a day later there are still remains visible, you should remove the carcass.

How to Determine If Your Ghost Shrimp Is Dead or Just Molting?

Dead shrimp and molting ghost shrimp have one key difference: the former sinks to the bottom while the latter will rise. Additionally, decomposing shrimp turn pinkish while those that are molting become white.

Also, it’s worth mentioning that a molting shrimp won’t stay still. Once the molting process is complete, the creature will start moving again and you’ll see its old exoskeleton in the water.


Do Ghost Shrimp Turn White When They Die?

Ghost shrimps turn pinkish when they die, and this can happen for a variety of reasons. Some common causes include molting issues, improper male-to-female ratios, and poor water quality.

Do Ghost Shrimp Eat Other Dead Ghost Shrimp?

Sometimes they would eat dead shrimps, but other times they wouldn’t. If you’re not sure whether or not your ghosts are eating dead ones, it’s best to err on the side of caution and remove any carcasses as soon as possible.

How Do I Know When My Ghost Shrimp Is Molting?

There are a few key signs to look for when trying to determine if your ghost shrimp is molting. These include staying still and not moving, developing a white band at the head-to-tail border, and becoming slightly transparent.

Is My Ghost Shrimp Dead?

One of the best ways to tell if your ghost shrimp is dead is to check whether it’s sinking to the bottom or rising toward the surface. Additionally, look out for signs of decomposition like pinkish coloration and a lack of movement.

If you suspect that your shrimp has passed away, it’s best to remove its body as soon as possible to avoid ammonia buildup and other potentially harmful issues.

How Long Does It Take a Ghost Shrimp to Molt?

Molting usually takes anywhere from 3 to 4 weeks, though this can vary depending on factors like temperature and water quality. If your ghost shrimps are still molting after several weeks, it’s best to have a chat with an experienced aquarium or shrimp expert for advice.

Last Words

Phew! That was a lot of information to take in. If you’re worried about why your ghost shrimp might have died, the key is to keep a close eye on your tank and try to identify any potential causes.

And if you do suspect that one of your shrimp has passed away, don’t hesitate to remove its body as soon as possible for the sake of your other tank inhabitants.
