When do tadpoles need to be put in a pound?

Tadpoles typically need to be placed in a pond when they are ready to transition from their aquatic larval stage to a more natural environment. This usually occurs when they are several weeks old, have absorbed their tails, and developed legs, indicating they are nearing metamorphosis. It's essential to ensure the pond has suitable water quality, vegetation, and minimal predators to support their growth and development. Additionally, timing should align with seasonal conditions to ensure a stable habitat.
