I read the recent email concerning Petco. It mentioned that sick animals are not to be put in the freezer. Though the company may have a legitimate reason for that, if a fish is to be euthanized, that is actually a very humane approach. Unfortunately, some university Animal Care and Use Committee personnel reject it since it is not approved for veterianarians. However, the fish simply slow down their metabolism, eventually it goes to zero, and the animals die a painless death.

I use it, and I think it is the best approach, rather than the (1) expensive, and (2) toxic MS-222 mentioned. Clove oil is an inexpensive and less toxic alternative to MS-222, but is not really necessary for euthanasia.
