Pixar fans were introduced to Ellen Degeneres’ Dory, the energetic and forgetful Pacific regal blue tang, in Finding Nemo, and 13 years after that release, she’s leading her own movie, Finding Dory.

Now that Finding Dory is almost here, it’s expected that the blue tang will be the new popular fish to buy, but that isn’t a good thing, according to marine biologists.
