Can A Turtle Go In A Fish Tank

Turtles and their habitat have always intrigued both enthusiasts and casual observers. A frequently asked question is, Can A Turtle Go In A Fish Tank? Let’s explore this query in depth.

Can You Reuse a Fish Tank for Turtles?

The short answer to this question is yes. However, before repurposing a fish tank for turtles, there are certain precautions to ensure the environment is safe. A fish, turtle, or other aquatic pet might have left bacteria or pathogens that could be harmful to new inhabitants.

Steps to Clean a Previously Used Tank:

  1. Take the tank outside for a thorough wash with dish soap. Rinse well.
  2. Fill the tank and add 4-5 cups of bleach.
  3. Stir the mixture for a few minutes and let it sit for approximately 30 minutes.
  4. Empty the tank and allow it to dry under the sun. The sun’s UV rays will break down any residual bleach.
  5. After drying, give the tank one final rinse.

It’s vital to test the tank’s PH levels and ensure stability before introducing a turtle.

However, it’s essential to note that turtles may occasionally eat fish. Before integrating them, it’s crucial to understand their nature and habits.

Advantages of Using Fish Tanks for Turtles:


  • Space: Turtles require spacious habitats. A general rule suggests 10 gallons for every 1 inch of shell length, per turtle. This means species like the red-eared sliders, which can grow significantly large, will need an appropriately large tank.

Alternative Turtle Habitats

While fish tanks are popular, turtles can also thrive in other environments:

Indoor Plastic Tubs: These offer a vast habitat indoors. They are budget-friendly but may not be the most aesthetically pleasing. Custom adjustments, like creating a basking platform and setting up filters, might be needed. Perfect for those who prioritize function over form.

Outdoor Pond

Outdoor Ponds: An ideal choice if space and resources are available. Turtles can enjoy a natural environment. Learn about creating an indoor or an outdoor turtle pond.

Best Turtles for Fish Tanks

Aquatic turtles are the best fit for fish tanks. Examples include:

  • Red-eared sliders
  • Painted turtles
  • Yellow-bellied sliders
  • Map turtles

These species naturally thrive in watery environments, making fish tanks ideal for them. The tanks provide ample swimming space, especially when paired with accessories like the Turtle Topper.

In Conclusion

For most aquatic turtle species, a traditional fish tank is the optimal choice. They’re attractive, easy to set up, and simple to maintain. However, always consider the turtle’s species, size, and specific needs when choosing a habitat.

If you decide on a different habitat like plastic tubs or outdoor ponds, ensure it meets the turtle’s requirements for a comfortable and healthy life.
