Clownfish and Damselfish

A group of scientist did an experiment on clownfish and damselfish larva and found out the acidification in the ocean environment can cause behavioral changes in fish. They got clownfish and observer them to see what they would do. The ones with low CO2 avoided the scent of the predator but the ones with high CO2 was oblivious of the scent. Which as you know would cause a higher rate of death in the fish. The damselfish were put in a maze. The ones with low CO2 would constantly turn one way right or left while the damselfish with high CO2 level would turn at random with no reasoning. The fish with a intermediate CO2 levels did show some slight changes that show the fish could probably change over time.
