Turtle care help anyone?

well one you need some rocks or gravel on the bottom of the tank so that it is not so slippery.two you need a filter and a platform.turtle pellats are good for them but in the wild they eat small fish like minnows,krickets,blood worms,meal worms,earth worth worms,snails,plants,and you can feed it sqash and carrots.unmature ones must eat two meals every day but when they are full grown adults they need to eat two meals every other day.make shure the tank has a screened lid.the water must be 4 or 5 inches in hight and atleast a little warm.it always needs access to water and i am so sorry this is so long.
