> MS-222 is expensive to buy. I did not know that Petco was supplying it
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).
