Overwintering Pond Frogs with Koi

Front-yard pond with koi (brought in for winter) and resident frogs. Found dead frogs during spring clean. Asks if frogs can move to aquarium.

Frog Overwintering Options

• Active indoors (warm, fed).
• Hibernating indoors (cold, unfed).
• In pond if deep enough (≥3 ft) with aeration.
• Relocate to deeper pond.
