I don't have a setup, but can give some advice--use a lift-out shallow plastic dish for a water area, rather than having the water directly in the tank. Water for amphibians must be very regularly changed (use chlorine/chloramine-free water).
Be sure the water dish is shallow enough for them to climb out easily, and the water is shallow enough for them to reach the surface of the water when they stand in it.
