Does a turtle tank need gravel?

Gravels are the most common substrate for the captive aquatic environment, such as turtle tanks. However, as the turtles do not require gravel to survive, so keeping the gravel in the turtle tank is not mandatory. 

They are suitable for turtle tanks as far as you can make sure that your turtle does not try to eat them. You can pick large rocks to avoid turtles trying to eat them by considering them their food.

They are functional and decorative for aquatic and semi-aquatic turtles. Gravels include various stones such as pebbles, cobbles and boulders that are classified according to size. A pebble can be as small as 2 millimetres and as large as 64 millimetres or 2.5 inches, that are more than double the size of a red-eared slider turtle and half the size of many pet turtles. You need to check for the size of the stone you are purchasing for your turtle tank as it is very important for the turtle.

The turtle can swallow anything it finds in the turtle tank, including the pebbles, if small enough to swallow. If they do this, it can lead to serious health issues like intestinal blockage and might require surgery. Make sure the size of the pebbles is bigger enough so that the turtles do not swallow them.

How many gravels should you put in a turtle tank?

The number of gravels for your turtle tank depends on the size of the turtle tank. If you have a bigger size tank, you need more gravel. If the turtle tank is small, you need comparatively less gravel. If you multiply the capacity of your tanks in gallons with the number of inches of depth, it will give you an approximate number of pounds (gravel) you need. 

Do not keep too many gravels inside your turtle tank as it traps dirt and debris. Use large stones instead of small ones as the large gravels will not trap as much debris as smaller ones. Also, it is less likely for the turtles to eat larger gravels than small ones. Hence, even if you keep fewer gravels in your turtle tank, you need to clean them regularly. 

You can keep the turtle in some temporary container and thoroughly clean the gravel. You can also do this by sweeping the gravel with a siphon-style aquarium vacuum. Make sure to press the siphon deep into the gravel to suck up the polluted water.


Gravels are the most commonly used substrate by turtle owners. Gravels are eye-pleasing and add an attractive look to your turtle tank. You can use gravels in a tank but ensure that the turtles do not swallow them. If the turtle swallows the gravel, it can lead to serious health issues in the turtle. Make sure to choose the size of the gravel properly, and it needs to be larger than the size of the turtle head. The smaller pebbles trap more dirt and debris than the larger pebbles. You need to clean the gravel regularly to keep the turtle tank’s environment clean.
