We have large terracotta pots in the pond for that reason....and now the little goldfish use those to hide in. The gold fish are quicker and they cannot get themI've heard to sink big PVC pipes w/ rebar cemented inside them for weight. Gives the koi a place to hide / escape. Then again, no more sushi for Katy and Tessa.
I love reading about everyone's pets!
We are sadly petless, having lost our English Bulldog last summer and our Shar Pei in the fall.
We are going to meet the litter that we are getting our Newf pup from tomorrow and we can't wait!
