Yes, shrimp do eat their molts! As a shrimp keeper for many years, I’ve witnessed this fascinating behavior countless times. The old exoskeleton serves as a valuable source of calcium and other nutrients that help shrimp build their new shell. Let me break down everything you need to know about shrimp molting and why they munch on their old shells.
What Exactly is Molting?
Before we dive deeper into why shrimp eat their molts let’s understand what molting is
Molting is when a shrimp sheds its external skeleton (exoskeleton) to grow bigger Think of it like a kid outgrowing their clothes – except shrimp wear their skeleton on the outside!
Some key facts about molting
- Adult shrimp typically molt every 3-4 weeks
- Young shrimp molt more frequently (every 1-2 weeks) because they’re growing faster
- Female shrimp molt more often than males
- Molting is necessary for breeding to occur
The Molting Process: A Step-by-Step Guide
The molting cycle happens in 4 main stages:
-
Pre-molt Stage
- Shrimp becomes less active
- Eats less food
- New skin starts forming under old shell
-
Molting Stage
- Shrimp absorbs water to break old shell
- Shell splits between head and body
- Shrimp wiggles free from old exoskeleton
-
Post-molt Stage
- New shell is super soft
- Shrimp hides to avoid predators
- Takes few days for shell to harden
-
Inter-molt Stage
- Period between molts
- Normal activity resumes
- Growth occurs
Why Do Shrimp Eat Their Molt?
Now for the main question – why do these little guys eat their discarded shells? Here’s what I’ve learned:
-
Calcium Recovery
- The old shell contains valuable calcium
- Helps build strong new exoskeleton
- Natural recycling process
-
Nutrient Conservation
- Other minerals are recovered
- Efficient use of resources
- Common behavior in nature
Should You Remove Molts from Your Tank?
Here’s my advice based on years of keeping shrimp:
Leave the molts in if:
- Your shrimp colony is healthy
- No disease outbreaks
- Tank parameters are stable
Remove molts when:
- Dealing with parasites
- Bacterial infections present
- Disease outbreak in tank
Common Molting Problems to Watch For
Even though molting is natural, things can go wrong. Here are some issues I’ve encountered:
1. White Ring of Death
- Clear white line around shrimp’s body
- Shell splits wrong way
- Often fatal if not addressed
2. Stuck Molts
- Shrimp can’t escape old shell
- May appear motionless
- Can be caused by poor water conditions
3. Failed Molts
Usually caused by:
- Wrong water parameters
- Poor diet
- Stress
Tips for Successful Molting
To keep your shrimp molting happily:
- Maintain Stable Water Parameters
General Hardness (GH): Species dependentCarbonate Hardness (KH): Species dependentTemperature: StablepH: Consistent- Provide Proper Diet
- Varied food sources
- Calcium-rich foods
- Protein-rich foods
- Algae and biofilm
- Regular Water Changes
- Max 15% weekly
- Match parameters closely
- Avoid sudden changes
My Personal Experience
In my shrimp tanks, I’ve noticed that sometimes one shrimp will eat another’s molt before the original owner gets to it! It’s pretty funny watching them scramble for these calcium-rich snacks.
One time, I freaked out thinking I had a dead shrimp in my tank – turns out it was just a perfectly preserved molt! That’s how realistic they can look. Now I know better and wait a bit before assuming the worst.
So yeah, shrimp definitely eat their molts, and it’s totally normal and healthy! It’s nature’s way of recycling important nutrients. As long as your water parameters are good and your shrimp are healthy, just let them do their thing.
Remember:
- Molting is natural
- Old shells = valuable nutrients
- Only remove molts if there’s disease
- Keep water parameters stable
- Feed a varied diet

How to Promote Healthy Molting in Freshwater Shrimp
To support healthy molting for fresh shrimp, consider:
- Regular Water Testing: Maintain stable water conditions.
- Balanced Diet: Offer calcium-rich foods like cuttlebone, spinach, and shrimp-specific pellets.
- Proper Tank Setup: Include freshwater plants and hiding spots for post-molt recovery.
- Monitor Behavior: Observe changes that may indicate molting issues.
Caring for Freshwater Shrimp During the Molting Process
To ensure a stress-free molt for alive shrimp, follow these care tips:
- Avoid sudden water changes to prevent osmotic shock.
- Provide mineral supplements like calcium and iodine.
- Do not remove molted shells immediately, as shrimp consume them to replenish lost nutrients.
- Minimize disturbances during and after molting.
Why shrimp are molting (shedding skin)? Should you remove shrimp molt?
FAQ
How long does shrimp molt last?
However, younger shrimp will change their skin more frequently, every 1 to 2 weeks, to be precise. This is because young shrimp experience a faster growth process. Meanwhile, replacing old shells with new shells in shrimp only takes a few hours.
Are shrimp happy if they molt?
If they’re grazing and molting, they’re probably doing all right. I had a hard time spotting my first 10, but after they bred to a bigger number and got used to the tank, they’re almost constantly out and about.
Do shrimp molt?
Sharing is caring! If you’ve ever kept shrimp as pets, then you’ve probably noticed they undergo a process known as molting. In layman’s terms, molting means that shrimp basically shed their exterior shell at certain periods in their life cycle.
Is my aquarium shrimp molting?
Even though shrimp molting their exoskeleton is completely normal, some fishkeepers mistakenly believe their shrimp to be dead. This guide will help you avoid such mistakes in judgment, and let you troubleshoot any possible molt problems with your aquarium shrimp. Why is Your Aquarium Shrimp Molting?
Why do shrimp die after molting?
Most of these problems stem from two reasons: Issues with the water parameters or diet. Sometimes, you may find a shrimp died after molting because it got hurt while vulnerable. The most common reason shrimp fail to molt is due to subpar water parameters.
Why do shrimp hide after molting?
Molting is a natural process that allows shrimp to grow and develop properly. During molting, the shrimp sheds its old exoskeleton and remains hidden until its new shell hardens. Molting is a sign of a healthy shrimp and a necessary process for the shrimp to continue growing and thriving in the aquarium. How long do shrimp hide after molting?
How to increase molting of shrimp?
However, once it attains adulthood, the molting will slowly decrease and come near to zero, when fully grown. You can boost or reduce the molting by controlling the water temperature, water parameter, and diet. However, when the molting starts, you should observe the shrimp regularly to avoid the problematic issues related to the process.
How do you know if a shrimp is molting?
Generally, speaking, there are some telltale signs a shrimp is preparing to molt. The most obvious sign is when you notice your aquarium shrimp standing still without moving much, or at all. This is what I personally call the “shrimp freeze” and can last for an hour or longer at times.
