Big surprise for two men who ate this bland-looking fish...LSD-like hallucinations!
This rare occurence is known as ichthyoallyeinotoxism (hallucinogenic fish poisoning). It comes from eating the heads or body parts of certain species of herbivorous fish after they ate some potent algae.
According to fish expert Matt Clarke, the effects of eating ichthyoallyeinotoxic fishes, such as certain mullet, goatfish, tangs, damsels and rabbitfish, are believed to be similar to LSD, and may include vivid and terrifying auditory and visual hallucinations. Thus the common name: "dream fish."
Just in case any enthusiasts decide to go out looking for "electric fish," be aware that your results may vary.
