I do not consider rude to have different opinions than mine.
If you have a mosnter tank, which yours is not, everything is possible. If you have an atomic filtration sstem, everything is possible.
If you speak of a public display sized tank, it is possible.
In your tank, the ammonia and waste excreted by the turtles will destou the water. Period.
Try with a more common fish. Do an experience with convicts or whatever. Do not sacrifice a Saratoga, which, by the way, is too big for your tank, once grown.
