What Size Tank Do I Need For 2 Turtles?

The rule of 10 gallons per inch of shell only works for one turtle. For each turtle added to an enclosure, increase the tank’s surface area by at least another square foot. For example, one 7-inch spotted turtle can live in a 40.5” x 32” x 24” tank. Two should be kept in at least a 52.5” x 44” x 24”. In general, bigger is better.

They will happily use as much space as you give them.

Smaller aquariums limit the range of natural behaviors your pet can express. They also become dirtier faster which leads to a higher risk of stress and illness.
