Some of use may have put have put koi in our bathtubs in an emergency, but how about carp to keep alive until our Christmas feast?
 
"Picture the Czech idyll. It’s the evening of 24 December, and one’s immediate family are sitting down to the Christmas Eve meal, the highlight of the festive season. 
In the days beforehand, you would have visited one of the thousands of carp sellers that line the streets of the country. 
For the traditionally minded, you would have bought your carp alive and kept it in the bathtub until 24 December."
