Psilocybin Turns a Fiercely Aggressive Fish Surprisingly Calm

Researchers found that psilocybin, the active compound in magic mushrooms, made a highly aggressive fish species noticeably calmer. The result suggests the substance can alter aggressive behavior in nonhuman animals.
The study examined a fish species known for intense aggression. Researchers reported that exposure to psilocybin, the active compound in magic mushrooms, produced a noticeably calmer behavioral state in the animals.
The result suggests that the substance can alter aggressive behavior in nonhuman animals. It points to a wider neuroscience question: how such compounds may influence behavior in animals other than humans.
This finding could draw interest from neuroscientists, animal-behavior researchers, and people following psychedelic science. It may shape how such compounds are studied in animals and could influence public discussion of psychedelics, though any societal effect would depend on further research and interpretation.
