I agree with Hammerman, giving such advices like killing all toads and frogs in our ponds based on possible infections is totally irresponsible. I just bought 1 goldfish and 1 koi fish yesterday evening and they were happy and fearless in my pond when I put them there. However, this morning I don't see them, so either they were frightened by something or they were humped by the toad(s) as I learned from your discussions here. I have some small cactus around my pond to discourage the overpopulation of toads, especially the venenous one, as I want to replace my previous Frenchie, and I am afraid that the new puppy will sniff a venenous toad etc... So now I have probably only one toad/frog, not sure, will shoot a picture and try to figure out. Here in the Grove these toads and frogs have a lot of places to go other than my pond, without emptying my pond to exterminate whatever, especially when they are sitting in the bushes around it ! Thank you for the valuable info.
