Answers:
* Turtles don't exactly have ears, not like mammals do, but they have structures that allow them to hear.
*If your turtles are young, less than two years old, you should feed them twice a day. If they're adult turtles, you can feed them once a day. Feed each turtle an amount of food roughly the size of its head.
*The Repto-Min floating food sticks are a great choice. Jurassi floating pellets are also good. You can also feed your turtles small live fish (just dump some into the tank, they'll chase them down), live plants like anacharis or duck weed, fruit, and vegetables, just not iceberg lettuce, because it doesn't really have any nutritional value.
*Oh, words in English are pluralized with an s, not a z. I don't know if this isn't your native language, but it's not the way it's done.
