My turtle needs to advise!?

you sholdn't really spend your money on a 10 gallon tank. I have 2 red eared slider turtles who in a tank now my father and i are making an out door pond with a cage for them for shelter. It has cinder blocks all around and a broken rabit hutch for shelter. All we need to do right now is dig a hole in the ground and put a bowel of water so my turtles can swim and they'll have a place to rest and sun bathe. The sun's heat is better for them than a heating lamp. Turtle's always need a place to rest not only for warmth and sun light but for their health too. Turtles who live too much in water and have no resting place or light could get sick or shell rot. They could even get a pyramid shell which can never go away. My turtles are girls and came from a terrible pet store. We found dents and scratches on their shells from being thrown around by cruel people. Keep in mind that the boy turtles have longer claws than the girls. So if your going to use my advise and build one out doors make sure it's secure enough for her not to get out or preditors to get in. Turtles need alot of love and affection, like if they start to climb around the sides near you it means the want attenion. Turtles are knida picky when it comes to eating. They can eat worms, meal worms, and rod flooding sticks. If you have a special food that you give her make sure it's small or big enough for her to swallow it and once in awile give her meal worms as a snack for nutrions. Make sure if you have gold fish you want alive if you let them swim with your turtles make sure she is not hungry or else she start to eat the fish. And pay attention to your turtle alot even in a outdoor pen that do need alot of love.
