Suzita asked:


I have a large fish pond in my London garden, which has a thriving collection of mostly goldfish and one or two medium koi carp. The pond was here when I bought the house and I try to look after it well. Last week for the first time I bought two new fish – very small silver koi. I floated the bag they were in on the pond for two hours before releasing them into the pond. I haven’t seen them for three days – they could be hiding under the weeds, but my worry is that they have perished.

Any advice would be of great help. Thank you!
