Turtles and Frogs together?

Question
I have a 25 gallon aquarium are there any small turtles and frogs that can live together with the tank semi-filled with water? And what kind of maintainance would i have to do and how often.

Answer
You've got a couple problems off the start.

Turtles should have AT LEAST 5 gallons of swimming space per inch of turtle, with 10 being the norm, so a partially filled 25 gsllon tank would really only be adequate for a couple inches worth of turtle- and none wills tay that small for too long.

Next, turtles eat frogs- and if it can't eat them, they'll harass them. The smaller the tank, the worse the problem.

You can try tree frogs, but then you'll need a screened top and have to be pretty careful about opening the tank.
