We moved the two remaining fish into the half barrel and I screwed some lattice on top. It is just temporary until we catch the racoon and he goes on a little car ride.
You have my sympathy, although there are Racoons in my area I haven't had trouble with them. I think my dog and cats keep them away but every April - June I get Blue Heron invasions. Blue Heron's have had some expensive meals in my pond.
