It’s tricky to house two turtles together. Turtles are solitary animals, so if they don’t have enough space, they might fight with tank mates. If you house a bigger turtle with a smaller one, the risk of bullying is greater. Housing a larger and smaller turtle is possible, but you’ll need to take caution. Make sure there is enough space and the enclosure is set up correctly. Be sure to watch your turtles for signs of aggression and prepare to separate them if needed.
