Can yellow bellied turtles go in an tank of guppies?

Yellow bellied turtles should not be kept in a tank with guppies. Yellow-bellied turtles are omnivorous and will eat whatever they can fit in their mouths, and this can include guppies. In addition, yellow-bellied turtles can carry parasites and diseases that can transmit to guppies and other fish. Finally, yellow-bellied turtles can be quite large, and they can quickly overwhelm a small tank, making it difficult for the fish to swim and find food.
