Shrimp is an invertebrate species that comes with an exoskeleton covering its body.
Like all invertebrate species, molting and replacing this exoskeleton is indispensable to a shrimp’s lifespan.
Understanding the basics of this process and helping the shrimp molt successfully is vital for their healthy growth.
However, unacceptable conditions and unwanted accidents can lead to shrimp’s failed molt.
So, what are the reasons for shrimp molting failure? I will discuss this question in detail and bring you an in-depth explanation. Keep reading to find out!
What Causes Molting Failure In Shrimp
Bad molts or molting failures are inevitable for inexperienced aquarium owners.
Therefore, you should not panic yet but try to identify the causes of these problems. Here are some potential reasons leading to shrimp molting failure.
Water Parameters
Shrimps need suitable water conditions like temperatures and ideal pH levels, which increase the chance of successful molt.
Therefore, you should monitor the water parameters like general and carbonate hardness (GH and KH).
Improper Diet
Sometimes, a diet focusing on calcium and protein-rich food is not the optimal option for shrimps.
They need a diversified and balanced diet that provides them with all fundamental nutrients for successful molts.
Besides snowflakes and calcium enhancers, don’t forget to feed your shrimp algae, plants, and blanched vegetables to boost their growth and molting process.
White Ring
There’s a popular molting problem called the white ring, which hinders the molting process in your shrimps.
You can check for the signs of this disease, such as a line running around the part between the shrimp’s head and body.
Stuck In Molt
If the shrimp doesn’t move at all during the molting process, chances are it cannot get out of the molt.
The old exoskeleton may be damaged at some point, making it impossible for the shrimp to get out.
How To Solve Shrimp Molting Failure?
After identifying the cause, you should quickly develop suitable adjustments to shrimps’ living conditions and diet.
In the sections below, I will suggest some effective and simple methods to help you deal with shrimp molting failure.
If these solutions don’t work and your shrimps keep failing to molt, consult professional and aquarium veterinarians to check on their health states.
It’s likely that your shrimps are suffering from some severe diseases.

Blanched Vegetables
You should adjust the shrimp’s diet if they are consuming unsuitable food that hinders their molting span.
Find nutritious and fiber-rich vegetables that suit each shrimp species.
For example, the favorite food of Cherry shrimps is biofilm and algae.
If your shrimps keep failing to molt, feed them with blanched vegetables that are rich in calcium, minerals, and vitamins.
Don’t Rush To Solve The Problem
Many inexperienced owners may rush to help the shrimps manually by touching their molts or applying physical impacts.
However, these practices won’t help your shrimp but carry risks of fatal damage to the shrimp’s bodies.
When touching the shrimp’s body, you can easily damage its legs and exoskeleton.
Unless you have experience dealing with the shrimps’ bodies, always seek aquarium doctors to check on your shrimps first.
Feeding Crushed Egg Shells
The lack of calcium-rich components in shrimp’s diet is a prevalent cause of shrimp molting failure.
Therefore, you can supply shrimps with calcium by feeding them crushed eggshells.
If you have any leftover eggshells from cooking, don’t throw them away.
Wash the shells with clean water and bake them in the oven for some minutes to eliminate the bacteria.
Crush the eggshells in a mortar until they turn into a powder-like texture.
Feed each shrimp around one pinch of this eggshell powder to supply it with calcium.
Preventions Against Molting Problem In Shrimps
Try to minimize the changes in water pH and temperature as much as possible to reduce the risks of molting failure.
You can change one-fourth of the total water supply in the tank once a week to reduce this change.
Each shrimp species has its ideal water conditions and living temperatures.
If you raise multiple shrimp species in one aquarium tank, ensure they have compatible characteristics and living conditions.
Feeding shrimps with a nutritious and calcium-rich diet is vital for their healthy development and successful molting.
My recommendations are algae, blanched veggies, and biofilm, which make excellent nutrient supplies for shrimps.

FAQs
The answers below will give you more information relating to shrimp molts and their molting process.
Check out the following sections to learn more!
Is It Advisable To Remove Shrimp Molts?
No, the molts will slowly dissolve or get eaten by fish and shrimp, so you don’t need to remove the molts.
However, the molts infected with bacteria or left in the tank for too long should be taken out.
Do Shrimp Eat The Molts?
Yes, shrimps love eating their molts left in the tank, which is an abundant source of calcium and minerals.
These nutrients can enhance the shrimp’s formation of its new exoskeleton.
How Long Do Shrimp Molts Last?
The molting process in shrimps typically lasts from 12 hours to one and a half days, depending on the shrimp’s state and environmental conditions.
During this time, the shrimp will recuperate and regain its energy from the previous molt.
How Many Times Does A Shrimp Molt?
Adult shrimps typically molt every 3 or 4 weeks if they have proper body conditions.
Meanwhile, the molting frequency in younger shrimps is higher, happening every 1 to 2 weeks.
Is My Shrimp Dying Or Molting?
The dead shrimps and molts may be hard to differentiate at first glance, but there are clear differences in their appearances.
While a shell looks like a living shrimp, the dead ones will feature a mildly pinkish color.
Final Thoughts
Failure in the molting process can significantly affect the shrimp’s healthy growth and living conditions.
The main reasons for this problem come from improper water conditions, diets, or diseases in shrimps.
Therefore, you should identify these causes and come up with proper solutions to protect the shrimps’ health.
