Finding Dory will make the blue tang fish popular and that’s not a good thing

When Pixar’s Finding Nemo was released in 2003, it unleashed a tidal wave of demand for the cute orange clownfish, the species that the character Nemo is based on. Sales of clownfish rose as much as 40%, according to some estimates. Some scientists were concerned that the population of the fish would be severely depleted if too many were caught in the wild. Aquarists, however, soon figured out how to breed clownfish in captivity, reducing the impact of lots of them being taken from coral reefs.
