that reminds me..

a lot of people use freezing as a way to euthanize fish, but I read that they can actually feel themselves freezing, so I know a lot of people chose to put them in clove oil instead because this just makes them fall asleep.

"When cold blooded animals become chilled they cannot move so their death appears peaceful but there is some evidence (I cannot remember where I read this as it was 7 yrs ago when I was researching this subject in regards to humanely killing frogs). However, the animal can feel the pain of ice crystals forming in the body while it freezes. The eugenol method as written above is far more humane since I believe it is an overdose of anesthetic which stops nerve function thus eliminating pain. We switched from freezing to using an overdose of an anesthetic (the active ingredient in Anbesol) for frog euthanasia."

heres the link where I found that info:

actually if anyone has any proof that fish can indeed feel themselves freezing Id be interested in hearing/seeing it, since this person isnt 100% sure. hopefully I wont need to be using any of these methods in the near future though. my fish are all doing well and I hope to keep them healthy! :O its very distresing to watch a sick-beyond-repair fish suffer for days though. I wish I knew about fish euthanasia when amadeus was dying.
