Will Cha Cha survive? At the koi club meeting yesterday, there was discussion about changing some of the pond water out, even in the winter. Since the temperatures are in the low 40s this week and the ice is retreating, we decided to change out a few inches. In the process, one of our missing koi showed up…about 90% dead – but that means 10% alive. So we’re experimenting with a little salt therapy and quarantined Cha Cha in a box with oxygen. Cha Cha will be renamed Lazarus if he/she returns to the pond.
