Dead Goldfish Aren't So Bad

Normally, I would have been very unhappy to discover two of my goldfish dead in the pond, but the good news is that these two moved into our first "raccoon-proof" pond more than two years ago, after living at least one year in a Portola classroom fish bowl. They survived many fishing attempts by marauding raccoons the past late summers-early falls and seem to have lived out their goldfish lifespans.

After taking the plants out yesterday afternoon, there was still at last 15 inches of water space at the bottom, as well as space at the top of the "squarepond". Before deciding to remove the pond

So now I have an opportunity to "remodel" the pond area again. It's been three years since I built the current configuration; this coming weekend, I'm going to try connecting the two ponds and giving the two koi and the four other goldfish a bigger home. Tom has his doubts that it will work since I'll need to connect the smaller pond to the bigger one with two separate pond liners and a channel under the bridge for the fish to travel between water holes. There is definitely the possibility of creating a big leak or dirt collapse, so wish me luck!This week's configuration
