I will have more also Cheryl. I will just be adding another deicer. We have raccoon trouble here but mostly with our trash when they can get it.
I have had pretty good luck with them not really bothering my fish. I am sure it is because the water lilies need thinned and they can't get to them.
I try to stay away from the Koi, they are gorgeous but they cost to much to risk loosing for me.
