Keeping the Peace: Selecting Safe snapping turtles tank mates

Keeping snapping turtles as pets brings no shortage of challenges. Their reputation for nipping fingers precedes them! But many enthusiasts discover their worse bite is reserved for potential tank mates.

With primal hunting instincts and powerful jaws evolved to crush prey, common snappers view most species as appetizers unless trained otherwise.

Despite difficulty earning their trust, certain animals can safely occupy snapping turtle habitats if given adequate provisions.

Through trial and error, some have even successfully integrated small communities featuring their cantankerous reptile stars.

This blog shares compatible snapping turtle tank mate options for experienced aquatic hobbyists, along with essential safety precautions all should heed.

Good Tank Mates for Snapping Turtles

Snapping turtles have a reputation for being territorial, solitary animals in the wild. Even as pets, they can be cantankerous and dangerous to keep with smaller or timid species. The ideal snapping turtle tank mate will be:

  • Large enough not to be considered prey
  • Able to fend for itself against displays of aggression
  • An active swimmer that can evade snapping bites
  • Non-territorial and unlikely to pick fights

Given those criteria, the following animals can make for appropriate tank mates:

Large Fish

Fish like koi and goldfish are fast enough in the water to avoid hungry snapping turtles. Their large size—6 inches or longer—is also generally off the dinner menu. While snappers may attempt to bite or intimidate fish, these species should be able to coexist safely.

Other Large Turtles

Certain turtle species thrive in groups and do well with aggressive tank mates. Red-eared sliders, map turtles, and river cooters all enjoy basking and typically avoid confrontation.

With adequate space and basking platforms for each turtle, they can make for interesting snapping turtle housemates.

Bottom Dwelling Fish

Bottom feeders like plecostomus, loaches, and catfish dwell in tank areas that snappers rarely occupy. Left alone and given shelter, algae eaters and scavengers can help clean up debris without drawing negative attention.


Snails, crayfish, and crabs armor themselves against predators. Providing additional live foods for snappers, many thrive in turtle setups. Just beware that cranky turtles may still attack slower-moving inverts if easily provoked.

Can You Keep Tank Mates with Snapping Turtles?

In general, if you select the suitable species and house them properly, snapping turtle tank mates can enrich pets’ lives.

Turtles are intelligent animals that may become bored or frustrated alone. Appropriate companions encourage more natural behaviors in captivity.

However, the decision should not be made lightly. Snapping turtles can reach over 2 feet long, boasting powerful jaws and territorial attitudes.

Only experienced aquarists should attempt mixed-species habitats. Beginners are better off housing common snappers solo.

Why Are Small Fish Not Safe from Snapping Turtles?

Snapping turtles feed on small fish, frogs, and even ducklings in the wild. Even well-fed captive turtles retain these feeding instincts for live prey.

Unfortunately, that leaves little guppies, tetras, and other petite fish extremely vulnerable around hungry snappers.

Within seconds, turtles launch themselves to bite and then swallow tiny tank mates whole. Aggressive snapping bites can maim or kill larger fish unlucky enough to venture too close.

Simply put, most common freshwater fish make very risky, if not lethal, snapper companions.

Snapping Turtles Eat Fish

Here are some examples of hapless fish that often appear on snapping turtles’ live food menus:

As you can see, fish do not tend to fare well around hungry snapping turtles! Owners must provide ample feeder fish or other meaty foods to divert snappers from viewing tank mates as appetizers.

Tank Setup Considerations 

Snapping turtle enthusiasts who wish to add compatible tank mates should be prepared to accommodate everyone’s needs. Here are some habitat considerations:

  • A 100+ gallon tank is strongly recommended
  • Powerful filtration to handle waste from messy feeders
  • Basking platforms and heat lamps for every turtle 
  • Hiding caves, decor, and sight barriers to reduce conflict 
  • Smooth substrate like river rocks to prevent impaction when eaten
  • Additional protein-rich foods to divert snappers from prey

With careful planning, snapping turtle aquariums can safely house organisms other than feeder fish. But the habitat must check the boxes for all inhabitants in terms of security, terrain, temperature gradients, and nutritional needs.

Why Are Other Species of Turtles Not Safe with Snapping Turtles? 

Sadly, many small to medium turtle species aren’t appropriate snapping turtle tank mates due to their modest size and non-aggressive natures.

For example, musk turtles, mud turtles, and box turtles may fall prey to bullying—even predation.

Likewise, slow-moving semi-aquatic types like Eastern painted turtles can’t readily escape snapping bites. Fingers, tails, and legs are unfortunately at risk around nippy common snappers and alligator snappers.

Given their 100+ year lifespans, it’s best not to take chances mixing vulnerable turtle varieties.

Can You Keep Multiple Snapping Turtles Together?

Interestingly, some snapping turtle enthusiasts have had success housing small groups long-term. Juveniles and subadults often tolerate snapper company better than solitary adults.

If attempting a multi-snapper habitat, provide 200+ gallon tanks with partitioned basking platforms. This grants each turtle a safe zone and may decrease territorial scuffling.

Still be prepared to separate bullying individuals if aggression escalates over time. Generally, one snapper per tank remains the safest approach.  

Can You Keep Crabs with Snapping Turtles? 

Yes, some freshwater crab varieties can work! Vampire crabs and Thai micro crabs fare better than slow fiddlers with their speed and reclusive ways.

Ensure each crab has sandy burrows or rock piles to disappear into when feeling vulnerable.

Also, recognize that crabs sometimes nibble resting turtles, risking defensive bites.

So, while compatible, you may need to treat injuries if housing feisty crabs and snappers together occasionally. Their armored shells help protect against severe turtle damage if scuffles ensue.

Can You Keep Snails as Tank Mates with Snapping Turtles?

Surprisingly, yes—ramshorn, mystery, apple, and nerite snails can occupy the same turtle tanks safely. Their rugged shells protect tissue, allowing snails to retreat and close up at signs of danger. 

Just know that juvenile snappers may eat small ramshorns and mysteries, needing alternative foods until they mature. By one-year-old, though, most lose interest in snails. They prefer juicier feeder options. So, the combo can work nicely in established aquariums.

As a bonus, snails help eat nuisance algae and waste. Their low bioload also makes them an ideal cleaner crew in addition to handling messy snapper leftovers. 

Can You Keep Frogs with Snapping Turtles?  

Frogs and newts are best admired from a safe distance outside snapping turtle enclosures! Their small size, delays in escaping danger, and delicate skin leave amphibians extremely vulnerable as tank mates.

Even an average 5-6 inch juvenile snapper can easily bite legs and tails or fatally wound petite frogs and salamanders while hunting.

Until common snappers mature and ignore live foods, fast-moving creatures literally ‘jump’ onto their menus given any opening.


While notoriously aggressive, snapping turtles can share space with select tank mates, given careful selection and plenty of resources.

Favorite options include large hardy fish, more giant turtle species, scavenging bottom feeders, and armored invertebrates like crabs and snails. 

Conversely, small fish, frogs, salamanders, and tiny turtles should never occupy snapper habitats long-term due to imminent risk.

Rear juveniles solo whenever possible, only attempting companions once mature and less likely to demonstrate predatory behaviors. 

With extra planning and precaution, multi-species snapping turtle aquariums can thrive! Just be sure to provide security, nutrition, and adequate living space if taking on the challenge of these commanding freshwater pets.

Here are some important frequently asked questions (FAQs) related to keeping snapping turtle tank mates:

Can I keep small fish like guppies or tetras with a common snapping turtle?

No, small fish should never be kept with snapping turtles. Even if the turtle is well-fed, it will likely attack, bite, and potentially eat little fish. Snapping turtles are quick, powerful predators that view tiny fish as prey, posing an imminent threat in shared enclosures.

What are some optimal snapping turtle tank mates?

Some of the best snapping turtle tank mates include large koi, goldfish or other hardy 6 inch+ fish, bigger peaceful turtle species like sliders, bottom feeding catfish/plecos, crayfish, crabs, and snails. These animals can hold their own and are often ignored by mature snappers when provided enough live foods and habitat resources.

Is it safe to keep snapping turtle juveniles together?

While risky, some enthusiasts have success raising small groups of young snapping turtles under 5-6 inches in 200+ gallon partitioned habitats. However, adults tend to be far more territorial and aggressive, often attacking or cannibalizing tank mates. Breeders usually separate snapper hatchlings before sexual maturity to prevent confrontation, injury or death.
