Why Can’t I Find My Shrimp in My Tank? Molting, Hiding, and Dead Shrimp in Your Tank

If you’ve ever wondered “where did my shrimp go?”, this post is for you. We’ll discuss the three most common reasons why shrimp disappear from aquariums: molting, hiding, and death.

What are the common causes of shrimp disappearing from a tank?

Trapped Inside the Filter Intake Tube

The filter intake tube can be a dangerous place for shrimp because of the powerful currents and suction that can occur.

If the filter intake tube is not properly covered with media, shrimp can easily become trapped in it due to the strong currents and suction.

This can lead to them getting stuck or even killed if they are unable to escape.

Tankmates are aggressive

If you find that your shrimp are constantly disappearing, it’s possible that their tankmates are to blame.

Aggressive fish or invertebrates can easily kill and eat shrimp, so it’s important to choose tankmates carefully.

If you already have aggressive tankmates, you may need to remove them or set up a separate shrimp-only tank.

Jumped Out Of The Tank

Shrimp may jump out of a tank if the water parameters are not ideal or if there is a plant or decoration that protrudes outside of the tank.

To prevent this, an inch or two gap between the water and the top of the tank should be left to discourage any shrimp from jumping out.


One of the most common causes of shrimp disappearing from a tank is molting.

Molting is when shrimp shed their exoskeleton in order to grow. This process can take anywhere from a few hours to a few days, and during this time the shrimp are very vulnerable.

They will often hide away in order to avoid predators. Molting can also be stressful for shrimp, and sometimes they will not survive the process.

If you think your shrimp may be molting, check for any shed exoskeletons in the tank. You may also see the shrimp hiding in caves or other hiding spots. If you see a shrimp that looks like it is molting, do not disturb it.

Where do shrimps hide in tanks?

1. In live plants

Shrimps often hide among plants at the bottom of tanks in order to avoid predators or other dangers.

They may also find safety among fish that have been recently added to the tank.

To ensure that shrimps feel safe, it is important to provide them with hiding places near the front of the tank so they can easily find their way around.

2. Under driftwood

Shrimp may hide under driftwood in tanks as this provides them with a dark place to hide away from potential predators.

The driftwood also provides an ideal spot for molting, as shrimp shed their exoskeleton periodically throughout their lives in order to grow.

3. In caves and grottos

Shrimps often seek out dark and secluded places in their tanks to hide, especially when they are feeling stressed.

To provide shrimps with adequate hiding places, it is recommended that they be given rocks, fake plants, driftwood, and other decorations with small caves.

4. In crevices

Another common place for shrimp to hide in tanks is in crevices. This could be between rocks, behind plants, or anywhere else where there are small spaces.

Shrimp are very good at finding these places and making themselves hidden. If you cannot find your shrimp, check all of the nooks and crannies in your tank.

5. In PVC pipes

Shrimps may hide in PVC pipes in tanks to avoid predators, as they cannot swim well and do not like being in the water. These pipes provide them with a sense of security, as they can fit inside and be hidden from view.

6. Behind decorations

One place your shrimp might be hiding is behind decorations in your tank. If you have plants or other objects that provide cover, check to see if any shrimp are lurking there. Shrimp are often skittish and will dart away when disturbed, so it may take a little patience to find them.

7. In the substrate

Shrimps may hide in the substrate of their tanks to avoid predators and de-stress, as well as blend in with their surroundings by losing coloration due to stress.

They also use their bodies to create a refuge from predators by shaping and adjusting the substrate.

8. In filter intakes

To prevent shrimp from getting sucked into the filter, it is recommended to cover the intake with a media such as a sponge filter, HOB (hang on back) filter, or corner filter.

If a more powerful filtration system is needed in larger aquariums, using a sponge filter head instead of an open intake can help keep shrimp safe while still providing adequate filtration.

What is molting and why do shrimp molt?

Molting is a process that shrimp go through in order to grow and replace their old, worn-out shell with a new, larger ones. It occurs every month or so depending on the age of the shrimp and during this time they will typically hide from predators and other threats.

Molting is an indication that the shrimp are healthy and growing, as it provides them with essential nutrients for growth.

How can I prevent my shrimp from getting lost or hiding in my aquarium?

Adjust the tank size and environment for your shrimp

The size and environment of an aquarium can have a significant effect on the health and well-being of shrimp. For example, smaller tanks are easier to maintain with less water volume, but they may not be large enough for all of the shrimp in your tank.

It is also essential to cycle an aquarium before adding any new shrimp as this will help balance out ammonia levels, pH levels, and nitrates produced in the tank.

If there is too much waste in a small aquarium then it could cause problems for your shrimp such as stress or even death.

Keep your shrimp in groups

If you’re keeping your shrimp in groups, they’ll be less likely to wander off and hide.

Plus, they’ll feel more secure in a group.

Keep an eye on them though, as they may still molting and shedding their exoskeletons.

Choose the right tank mates

Choosing the right tank mates is important in preventing shrimp from getting lost or hiding in an aquarium because some small aquarium fishes can harass shrimps, leading to a stressful environment.

In order to prevent this, it’s essential to avoid aggressive fish, cichlids, and small rasboras when selecting tank mates for shrimp.

Instead, dwarf suckers, small tetras, and angelfish are good options for compatible tank mates for cherry shrimp. Keeping them in a separate tank with these compatible fish can help reduce the chances of the shrimp becoming lost or hiding.

Ensure the water is suitable for shrimp

It is important to maintain correct water conditions for shrimp in order to ensure their health and survival. This includes maintaining the correct temperature, pH level, GH level, KH level, TDS levels, and ppm of the water.

The ideal temperature for cherry shrimp is between 70-75 degrees Fahrenheit and a pH between 6.5-7.

Additionally, the GH should be 5-8 ppm and KH should be 6-8 ppm with a TDS range of 1-4 ppm and 150-250ppm.

Maintaining these parameters over time will help the shrimp balance out ammonia levels along with nitrates that are produced by them which are necessary for their growth process.

Add a few hiding pots

Hiding pots can be used to provide shrimp with plenty of safe hiding spots in an aquarium.

To make sure that the shrimp are still around, owners can try luring them out with their favorite food, such as pellets or blanched vegetables.

Leaving a bowl of this food out for 20 minutes will give owners an idea of whether their shrimp are still present in the tank.

Provide vegetables for your shrimp

It is important to provide vegetables for shrimp in an aquarium to ensure a varied diet and that the shrimp get all of their essential nutrients.

Caridina and Neocaridina shrimp should be fed foods such as canned sliced carrots, green beans, or blanched zucchini, which provide more plant content than their natural diets.

These vegetables also give them the energy to molt. It is therefore important that aquarium owners provide these types of food sources to make sure the shrimp are healthy and well-fed.

Check if your shrimp are breeding

It is important to check if your shrimp are breeding because they can reach sexual maturity between two and three months of age.

Female shrimp produce pheromones which attract male shrimp, and mating will eventually occur. This can be difficult to detect if the female is hiding in order to protect herself from being eaten.

Checking for signs of successful breeding helps ensure that your tank remains populated with healthy, happy shrimps!


Should you remove dead shrimp?

Removing dead shrimp from a tank can have various consequences. If the tank is small or there are not many shrimp or snails present, it is best to let the body decay before consuming it as this can provide nutrients for the aquarium fish.

However, dead shrimp can also increase ammonia levels in the water which can lead to other issues such as contamination and toxicity.

Therefore, it is important to remove dead shrimp from tanks unless there are enough other creatures around to consume them.

Tricks To Bring Shrimps Out From Hiding

The little trick to bring shrimps out from hiding is to feed them their favorite food and wait 10-20 minutes for them to get interested in it. This way, one can easily check if the shrimp are doing well.

The benefits of shrimp in a planted tank

Shrimp is a great addition to planted tanks, as they can help maintain the water quality and provide natural food sources for other tank inhabitants.

By eating algae and plant material, shrimp help breaks down nitrates in the water, improving its overall health.

Additionally, shrimp appreciate having lots of plants for hiding and exploring in their tank environment.

The presence of live plants further helps reduce nitrates in the water which is beneficial for all organisms living in an aquarium ecosystem.
