How Many Red Eared Sliders in One Tank
Red-eared sliders are not very territorial and they tend to live together in groups in the wild. So, there is no reason why you can’t keep multiple turtles in a tank. However, since each adult red-eared slider needs to be housed in at least a 100-gallon tank it might be challenging to keep multiple turtles in a single tank unless you want to get a 200+ gallon tank.
In most cases, if you want to keep multiple red-eared sliders it’s better to keep them in a pond, or you should look into getting Rubbermaid Commercial Structural Foam Livestock Tanks, or the BOSWELL 470-Gallon Above Ground Turtle Pond.
Red Eared Sliders can get quite big, so it’s important to make sure the tank you get is large enough to comfortably house them. They also need a lot of plants and turtle tank decorations, both of which will take up space in the tank, and you need to remember that when you calculate how much room they’ll need.
The best way to figure out what size turtle tank you should buy is by using our Turtle Tank Size Calculator–it’s free and easy-to-use! You just need to enter some basic information about your slider (shell-length) to find out exactly how many gallons their new home needs to hold.
