Yep, I noticed the guppies too. They do a great job with the mosquitoes!
Loved the story about the Butterfly Koi, had much the same happen with a salt water aquarium once.........lost one expensive Butterfly fish to a very large anemone!

I love your fish. Your set up looks great. I recently purchased a small preformed 3' x 4' irregular shaped pond shell with a one level waterfall at a yard sale. The pump was not included. My pond project may not kick off till next year as I have many things to consider before installing it such as location, light, theme, and appropriate plants and inhabitants for such a small space. It will probably need to be extended. How large is your pond and have you had any luck with a smaller scaled version? You did a fantastic job!
we have a smaller preformed one like you described in the front yard and the one in the back yard has the soft rubber liner and is 700 gallons. also, more frogs will come!
