Just for future reference Beverly, if you every have to put something down that's from your tank. The most humane way to put down a fish or other creature would be to place it in a container with some tank water and place it in the freezer. I have only had to do this one, when first starting out. Most cases though, there is usually a second choice other than putting it down. 
 
cheers, Rich
