A brick now thats raw lol :lol:
I thought putting stuff in freezers were classed as "cruelty" these days?
from wiki
Unlike humans who fall asleep and die from the freezing temperatures, fish can actually feel the ice crystals forming on their skin causing immense pain and suffering before death. Fish do not pass out from cold as humans would and tend to live for hours at extreme temperatures before death.
Dont know as not a scientist but would a brick be nicer seems so harsh ahahahahah
