It depends on the size of your aquatic friend. If your turtle is the size of a fifty cent piece it should be cool.
smaller aqarium
YES, you can put a map turtle in the same tank with a slider.
you can put a turtle in a tank with no cover and it wont crawl out while you are sleeping
you can put fish in the tank but you can also put frogs in it too!
no the big turtle would eat him
tee hee
I don't see why not.
put it in your backyard or a pond
First if you have not already got a tank, go to a pet store and ask for the right size tank for your turtle. Also while you are there get at least 2 or more bags of gravel. Plus get some sand too. fill the bottom of the tank with the gravel and put a large hill goring up with the sand so your turtle can have land. put some small logs and drift wood into the tank so your turtle can hide. also put some aquatic plants in to so if you forget to feed it he/she can eat the plants. plus get a filter. then put your turtle in and he/she can enjoy the tank.
Yes. Not too much thought ;)
Put something in there for it to climb out of the water on.
Turtle will most likely kill frog eventually.
