Our back yard Koi pond was put in 20+ years ago. At first is was just Koi, but the water, and surrounding garden has grown, and critters arrived. The toads were first, and then a few frogs, then came the Five Lined Blue Tailed Skinks.
And the tiny little earthworm eating snakes.
We had a very dry August and for the first time ever, we had three different skinks come into the house. All of them were lucky, in that I managed to grab them and relocate them to the front garden area. Our male Dachshund chases and kills any he can get to.
I just ponce on the skinks and manage to hold them in my hand and not hurt them at all, they don't even drop their tails. They must like thee habitat, as they are plentiful in the neighborhood as my neighbors even mentioned seeing them as something new. They eat lots of bugs, so we like em! My wife acts like they are Gila monsters.
