I checked the pump filter when the water seemed a bit slow. After removing a couple of leaves, I gently lowered the pump to the bottom. Just as I did, I saw a pair of eyes looking at me from the water. That was all that was visible. Frog jumped to the stone and hid his head in the plants. He stayed motionless, and so did I. Maybe, just maybe, he was getting used to me. I slowly moved away and didn’t see him again until the next day. He was sunning himself on a different stone, then jumped into the pool above the big one. Both times, I saw only one frog.
