I am not sure what this video is trying to prove, even if it turns out to be fake. Animal studies have an important place in medicine, pharmacology & toxicology, but this is completely unnecessary amateur experimenting. So is freezing goldfish in ice cubes. I am going to lock this thread.
MFK is dedicated to fishkeeping excellence. For some monsters, this includes using animals such as goldfish as feeders. However, we differentiate this from and condemn cruelty to animals.
