I don't know why you asked. We told you what we thought, but you seem to be trying to convince us, and yourself, otherwise. Go ahead and give it a try. Maybe it will work out for a while.Even in a large pond, where is a 30" koi supposed to escape from a red-eared slider?
It requires more than space to allow a vulnerable animal to escape. They need an actual safety refuge.
As you can see from this video, a frog living in the same enclosure as a turtle doesn't have to share the same space.
If we created a barrier between the frog and turtle, the frog would have little space to roam at night when the turtle sleeps.
But even if the frog is unable to escape from the turtle one day, I would probably be content knowing that it lived a pretty good life. Maybe not the same quantity of life as a bullfrog in an aquarium, but a more quality life.
I would definitely not name any animal that coexists with Teresa.
