You can get clove oil at most any health food store or pharmacy and the fish
just go to sleep... Much to the bane of some ichthyologists because they
don't get the It's usually much less expensive at a health food store.
There's no chemicals to clean up or worry about, and gee, it smells good too

free. There might be some liability concerns, because it is not without
danger if unless used carefully. That is true of other chemicals that stores
supply, however.

carbon dioxide. Formalin is not considered humane by veterinarians, and the
American Society of Ichthyologists and Herpetologists recommends an
anesthetic like clove oil, MS-222, or carbon dioxide before immersing fish
in formalin for collections, if possible. Carbon dioxide does anesthetize,
but it suffocates too, if too much is given, and the fish die with their
mouths open. So, I'm not sure about humane, or even what that means with
fish (see below).
