Are There Any Aquariums With Mantis Shrimp – The Ultimate Guide
You’ve likely seen the viral videos of a creature with the fastest punch in the animal kingdom, or perhaps you’ve heard rumors of a live rock hitchhiker that decimated a local reefer’s cleanup crew. It’s natural to wonder, are there any aquariums with mantis shrimp that actually thrive without ending in disaster?
I’m here to tell you that not only is it possible, but keeping these members of the order Stomatopoda can be one of the most rewarding experiences in the hobby. They are intelligent, visually stunning, and possess personalities that rival even the most interactive pufferfish.
In this guide, we will explore how to build a safe, sustainable home for these “thumb-splitters.” Whether you’re a beginner looking for a unique desk companion or an intermediate keeper ready for a species-only tank, I’ve got you covered with practical, expert advice.
Are there any aquariums with mantis shrimp suitable for beginners?
The short answer is yes, but with a specific caveat: you must treat them as the “star of the show” rather than just another inhabitant. Most hobbyists who ask, are there any aquariums with mantis shrimp, are often surprised to learn that these animals don’t play well with others.
Because of their predatory nature, they are generally not suitable for a standard community reef. However, a dedicated setup is actually perfect for beginners because it allows you to focus entirely on the needs of one fascinating individual.
If you have a 10 to 30-gallon tank sitting empty, you are already halfway to owning one of the ocean’s most sophisticated hunters. Don’t worry—while they have a reputation for being “tank busters,” most species are perfectly safe in standard glass aquariums if handled correctly.
The Allure of the Peacock Mantis
When people think of these creatures, they usually envision the Odontodactylus scyllarus, commonly known as the Peacock Mantis Shrimp. This species is famous for its vibrant, rainbow-colored chitinous exoskeleton and its incredible punching power.
They are highly active and will often watch you from their burrow, tracking your movements with their complex, rotating eyes. Keeping a Peacock requires a slightly larger setup, but the interactive “pet-like” quality they offer is second to none in the crustacean world.
Understanding the Two Worlds: Smashers and Spearers
Before you go out and buy a tank, you need to know which type of mantis shrimp you want to keep. They are broadly categorized into two groups based on their hunting hardware: smashers and spearers.
Smashers possess club-like appendages used to crack open hard-shelled prey like snails, crabs, and even clams. These are the species most commonly kept in the hobby because they are generally hardier and more colorful.
Spearers, on the other hand, have barbed, spear-like appendages designed to snatch fast-moving fish from the water column. These species often require a much deeper substrate depth because they are ambush predators that live in vertical burrows in the sand.
Which One is Right for You?
For most home aquarists, the smasher variety is the way to go. They are easier to feed—often accepting frozen silversides or krill—and their interactive behavior makes them much more entertaining to observe than the more reclusive spearers.
If you are interested in the specific mechanics of their care, checking out a guide on unique pet characteristics can help you decide if their temperament matches your lifestyle.
Setting Up the Perfect Habitat
The key to a happy mantis is security. In the wild, they spend a large portion of their time in burrows or crevices in the reef. When considering are there any aquariums with mantis shrimp that look natural, the secret lies in the rockwork.
You want to provide plenty of live rock or high-quality dry rock. Many keepers like to “pre-drill” a PVC pipe and bury it under the rockwork to give the shrimp a head start on a sturdy, safe burrow.
For smashers, a mix of sand and rubble is essential. They are the “architects” of the sea and will spend hours moving pieces of rock and shell to reinforce the entrance of their home. It’s truly a joy to watch them work!
Glass vs. Acrylic: The Great Debate
One of the most common questions is whether you need an acrylic aquarium to prevent the shrimp from breaking the glass. While it is true that a large Peacock Mantis can technically crack thin glass, it is extremely rare.
If you are worried, you can place a thin sheet of acrylic or a piece of eggcrate (lighting louvers) on the bottom of the glass tank before adding substrate. This protects the bottom pane if the shrimp decides to dig all the way down and strike at a reflected “intruder.”
For most smaller species, like the G. smithii or N. wennerae, a standard glass aquarium is perfectly safe. However, choosing appropriate tank dimensions is vital to ensure they have enough room to roam without feeling cramped.
Water Chemistry and Dietary Needs
While mantis shrimp are generally hardy, they do require stable water parameters to facilitate a successful molt. Molting is the most dangerous time in a shrimp’s life, as they shed their old chitinous exoskeleton and remain soft and vulnerable for several days.
Keep your salinity at a steady 1.025 to 1.026 and ensure your nitrates are kept low through regular water changes. Iodine supplementation is sometimes debated, but providing a varied diet is usually enough to ensure they have the minerals they need for a new shell.
Feeding is the highlight of the day. Since they are highly intelligent, you can even “target feed” them using a pair of long tweezers or a feeding stick. This builds a bond between you and your pet.
A Nutritional Checklist
To keep your mantis in top shape, vary their diet with the following:
- Frozen Krill or Mysis: Great for daily nutrition.
- Fresh Clams or Mussels: Essential for smashers to exercise their clubs.
- Live Ghost Shrimp: Provides enrichment by allowing them to hunt.
- Silversides: High-protein snacks for larger species.
Always remove any uneaten food after a few hours. Because mantis shrimp like to “hoard” food in their burrows, a piece of rotting shrimp can quickly spike your ammonia levels. For more on this, look into their specific nutritional requirements.
Maintaining the Mantis Shrimp Aquarium: A Weekly Schedule
To ensure your Stomatopoda friend lives a long and healthy life, consistency is your best friend. Here is a simple maintenance routine I recommend for any specialized mantis setup.
| Frequency | Task | Why it Matters |
|---|---|---|
| Daily | Check temperature and behavior | Ensures the heater is working and the shrimp isn’t in a stressful molt. |
| 2-3 Times Weekly | Target feeding | Prevents waste buildup while ensuring the shrimp gets its calories. |
| Weekly | 10-20% Water change | Removes nitrates and replenishes essential minerals for the exoskeleton. |
| Monthly | Clean filter media | Maintains high oxygen levels and clear water for better viewing. |
Debunking the Myths: Can They Really Break Glass?
We see this question constantly: are there any aquariums with mantis shrimp that haven’t shattered? The “glass-breaking” reputation is largely exaggerated. Most incidents occur when a shrimp strikes at its own reflection on the bottom glass or a piece of food held against the side.
In a home aquarium, they are much more interested in their burrow than in attacking the walls. If you provide a deep enough substrate depth (2-4 inches depending on species), they will feel secure and have no reason to strike the glass.
If you are still nervous, stick with smaller species like the Neogonodactylus wennerae. These guys are common live rock hitchhikers from Florida and are virtually incapable of damaging even a standard 10-gallon glass tank.
Selecting Your Species: From Peacocks to Smiths
Not all mantis shrimp are created equal. Some are shy, while others are bold and inquisitive. Choosing the right one depends on your tank size and how much interaction you want.
The “Smithii” (Gonodactylus smithii)
If you want a hardy, colorful, and active shrimp for a smaller tank, the Purple Spot Mantis (G. smithii) is my top recommendation. They stay relatively small (about 3-4 inches) and are incredibly interactive.
They are known for their “mowhawk” of sorts and their vibrant purple spots on the inside of their smashing arms. They are less prone to hiding than other species, making them a joy to watch throughout the day.
The “Wennerae” (Neogonodactylus wennerae)
Often found as hitchhikers, these are the “tanks” of the mantis world. They can vary in color from bright green to deep red depending on the lighting in your tank. They are very hardy and perfect for those new to keeping Stomatopoda.
Troubleshooting Common Mantis Shrimp Issues
Sometimes things go wrong, even in a well-maintained tank. The most common issue hobbyists face is a “bad molt.” If you notice your shrimp hasn’t come out of its burrow for a week, do not poke or prod it.
During a molt, the shrimp is soft and can be easily injured or killed by stress. It is normal for them to seal the entrance of their burrow with sand and rubble. Just keep the water quality high and wait—they will emerge when their new shell has hardened.
Another common issue is algae growth. Since mantis shrimp tanks are often species-only tanks, you can’t just throw in a handful of snails to clean up, as they will quickly become an expensive snack. Instead, rely on manual removal and perhaps a few fast-moving, “disposable” hermit crabs.
FAQ: Common Questions About Mantis Shrimp Aquariums
Can I keep a mantis shrimp with any fish?
Generally, no. While some keepers have success with very fast, small fish like Damsels, it is usually only a matter of time before the mantis catches them. For the health and safety of all animals, a dedicated setup is best.
How long do they live in captivity?
Depending on the species, they can live anywhere from 3 to 7 years. Large Peacocks tend to have shorter lifespans in captivity if water temperatures are kept too high, so aim for a stable 76-78°F.
Do they need special lighting?
Most mantis shrimp prefer subdued lighting. In fact, high-intensity reef lighting can sometimes lead to shell disease in certain species. Use a standard LED and provide plenty of shaded areas and deep burrows.
Can they recognize their owners?
Many hobbyists believe so! Because of their advanced vision and high intelligence, they often learn to associate their “human” with food, coming to the front of the glass when you enter the room.
Conclusion
So, are there any aquariums with mantis shrimp that truly succeed in the long run? Absolutely. By understanding that these are intelligent, specialized predators rather than standard “clean-up crew” members, you can create a fascinating display that will be the talk of anyone who visits your home.
Remember to prioritize a secure burrow, maintain stable water parameters for molting, and provide a varied diet. If you follow these steps, your Stomatopoda will reward you with years of incredible behavior and unmatched personality.
Don’t let the “tank buster” myths scare you away. With a little bit of planning and a species-only tank, you can safely enjoy one of the most remarkable predators the ocean has to offer. Happy reefing!
