Hey there! I’ve been keeping aquariums for years, and one question that keeps popping up is whether mantis shrimp can survive in freshwater. Let me break down everything you need to know about these fascinating creatures and their habitat requirements
Quick Answer
Nope, mantis shrimp are strictly marine animals. They can’t survive in freshwater tanks – all stomatopods (that’s their fancy scientific name) need saltwater to live.
What Makes Mantis Shrimp So Special?
Let me tell you, these little guys are absolutely mind-blowing! Here’s what makes them unique:
-
They’re Not Actually Shrimp: Despite their name, mantis shrimp aren’t related to regular shrimp at all! They got their name because they look a bit like praying mantises.
-
They’re Super Strong These guys pack a serious punch! The “smasher” types can hit with the force of a .22-caliber bullet We’re talking about enough power to potentially crack aquarium glass – that’s why some folks call them “thumb splitters”!
-
Two Types of Hunters
- “Spearers”: Silent assassins that stab soft-bodied prey
- “Smashers”: The boxers of the bunch that crush hard-shelled prey
Housing Requirements
If you’re thinking about keeping a mantis shrimp, here’s what you need to know:
Tank Setup
- Must be a saltwater setup
- Should be kept alone (they’re not great team players)
- Need plenty of hiding spots
- Like to burrow and create tunnels
- Can grow up to 12 inches long (though most are smaller)
Why They Can’t Live in Freshwater
I know it’s tempting to try keeping these cool creatures in a freshwater setup, but here’s why it won’t work:
- Their bodies are adapted to process salt water
- They’ve evolved specifically for marine environments
- No known mantis shrimp species can survive in fresh water
Alternative Options for Freshwater Tanks
If you’re set on having something similar in your freshwater tank, here’s what I’d recommend:
- Electric Blue Crayfish: These guys look similar and are totally freshwater-friendly
- Regular Freshwater Shrimp: While not as powerful, they’re still fascinating to watch
- Freshwater Crayfish: Various species available with interesting behaviors
Caring for a Mantis Shrimp (In Saltwater)
If you decide to keep a mantis shrimp in the proper saltwater setup, here’s what you should know:
Pros:
- Super hardy
- Easy to feed
- Low maintenance
- Fascinating to watch
- Don’t need specific water conditions
Cons:
- Can’t be kept with other fish
- Might damage tank glass
- Need their own dedicated tank
- Can be aggressive
Signs You’ve Got an Unexpected Mantis Shrimp
Sometimes these little ninjas sneak into tanks on live rock. Here’s how to spot them:
- Missing Fish: If tank mates start disappearing mysteriously
- Clicking Sounds: Though this could also be pistol shrimp
- Sand Mounds: Look for tunnel entrances with piles of sand nearby
- Night Activity: They’re most active when lights are out
Removing Unwanted Mantis Shrimp
If you’ve got an uninvited mantis shrimp, here’s what we usually do:
- Use a water stream to flush them out
- Try the freshwater dunk method (for the rock they’re in)
- Set up night-time traps
- Use a net during dark hours
- Consider natural predators like triggerfish
Final Thoughts
While mantis shrimp are absolutely amazing creatures, they’re definitely not suitable for freshwater aquariums. If you want to keep one, you’ll need to commit to a proper saltwater setup. Trust me, though – if you do decide to keep one in the right conditions, you’ll never be bored!
I’ve seen many newbie aquarists try to force these guys into freshwater setups, and it never ends well. Remember, sometimes the best way to appreciate these incredible animals is to give them exactly what they need – and that’s definitely saltwater!

Common Sign of a Mantis Shrimp
When fish, crustaceans, and invertebrates start mysteriously disappearing from your aquarium, many aquarists suspect a mantis shrimp. While this is a key sign of their presence, other marine animals could also be the cause. Consider a mantis shrimp as a suspect, particularly if fish are disappearing, but thoroughly investigate other possibilities before jumping to conclusions.
Popping Noises: Mantis Shrimp vs. Pistol Shrimp
Some believe clicking, popping, or snapping sounds from your tank indicate a mantis shrimp. Others argue these noises suggest a pistol shrimp instead.
If you have a pistol shrimp, suspect it for the sounds. However, pistol shrimp are unlikely to attack or kill fish but may punch holes in hermit crab, snail, and other mollusk shells to feed.
As natural burrowers, mantis shrimp create tubes or cavities in sand, rubble, or mud. Look for holes or tunnels with mounds of sand or rubble outside them. Pistol shrimp also exhibit this behavior, so if you spot such a hole, dim the tank lights and observe what emerges.

Behavior. Mantis Shrimp can only live in Water and will slowly die if on land for too long, that is unless a Water Bucket is given to a tamed Mantis Shrimp to help it survive on land.
