My turtles have big aquarium, and they have a place where they swim, sunbathe... Today I made them a little cave. They like it, but they fight about it. My male turtle doesn't let a female to get anywhere near the cave and it is acting very aggressive. My female is now bored becouse she wants to be in a cave, so I am wondering what coud I make for my turtles that could be very interesting so they wouldn't be bored?
