These two movies changed the way we think about fishes. Kids were asking their parents to get them Nemo and Dory fish.

The 2016 movie revolved around the adorable, little, and suffering from short-term memory loss blue-colored fish. However, real Dory is significantly different from the movie counterpart.

Species of Dory

Many kids asked their parents, “Is Dory a real fish?” A lot asked to keep it as their pet. Though the beloved fish of ours, most of us don’t know the real name of Dory.

Dory is the Pacific Blue Tang Fish or the Paracanthurus hepatusas per the scientists. Dory belongs to the family of surgeonfish.

Although the name implies that it is blue, the actual color changesnear to white at night.It’s one of the details missing from the movie. During childhood, they are yellow.

What do the blue tangs eat?

Like the other members of the surgeonfish family, blue tang fish are herbivores. They feed on the algae.

Their role in the food chain is to maintain the coral reefs. Also, by feeding on the coral reefs, they keep them healthy.

Memory issues

In the movie, Dory has a terrible short-term memory, which is funny yet sad. Although that makes her a gullible, adorable, and lovely fish, that’s hardly the case. Contrarily, in real life, the blue tang has an impeccable memory, just like any other fish.

The behavior of blue tang/Dory

Behave of Dory Fish

The Dory in both of the movies is fun-loving and jolly. However, the reality is disappointing. The seemingly merry blue tang is more aggressive than the shark. The temper becomes worse when two blue tangs are together in a tank. One tends to exert dominance over the other.

Capturing Dory

Thanks to the animated movies, there was a significant increase in the sales of the fish. This huge demand is turning to be detrimental for the species.

Moreover, the fishermen capture the blue tang using cyanide to bring them up, which isn’t the smartest way. Cyanide damages the water, the environment, destroys the coral reefs, and kills the fish.

As you may have figured it by now, having a pet Dory isn’t good for the fish, for the environment, andthe other fish in the tank. So, it’s best to keep it alone where it belongs, in the wild water.
