Frogs in the Buckets

A couple of months ago we added a half dozen 20 gallon buckets to grow additional plants and grow our baby fish. After the baby fish were moved to the small pond, a couple of green frogs decided to make a bucket their home. I guess the frogs are pretty teritorial as I only see one per bucket. I haven't ever seen a frog fight but somehow they seem to know which bucket is already taken and so they move to a vacant bucket to set up home. Here are two different frogs in two different buckets.
