I'm planning on building a nice display setup for dart frogs. I'd like to throw a turtle in there and need some suggestions. I need a species that doesn't get very big (no more than 5" or so full grown) can handle the temps related to the frogs (70-80) and won't try to eat the frogs. I definitely plan on doing some research before I get the turtle but I don't want to research every turtle under the sun looking for the right one. Some suggestions on where to begin would be greatly appreciated.
