You can call your local pet shop and see if they’ll take the turtles. If you choose to keep them, the tank is perfect, make sure they have a UVB light/lamp, a dry deck to come out of the water, and a water filter. They eat dry turtle food, live goldfish/krill/shrimp, or frozen krill/shrimp/bloodworms. It is important to know what type of turtle you have that way you can accommodate them better.
