What type of fish is Nemo?

In this blog, our main topic will be what type of fish is Nemo. Apart from that, we will also discuss the characteristic features of this class and how they adapt to the environment and survive in the wild.

What type of fish is Nemo?

Nemo is a member of Clownfish, a type of anemonefish. It is one of the thirty clownfish species that have their habitat in the warm waters of the Indian and Pacific oceans, with yellow, orange, red and black whitish streaks or bars.

What are the characteristics of the Clownfish?

Clownfish are falsely known as anemonefish with a similar orange colour tinge that you might have observed in Finding Nemo with distinct white bands with black outlines:

  • They are small animals with bodies reaching up to 11 cm long on average.
  • Nemo or clownfish are hermaphrodites that are both male and female.
  • They are born male and can change their sex to female. It happens mostly when a dominant female dies. Dominate males will change to females and will then mate with other males. Once they change their sex, they can’t change it back.
  • They are omnivores and can eat both plants and animals. 
  • The diet of Nemo consists of algae, zooplankton and small crustaceans. 
  • They have a symbiotic relationship with sea anemones. 
  • Clownfish have a protective mucus layer to protect them from sea anemone toxins they produce to capture their prey. 
  • Sea anemones protect them from predators; in return, they remove the parasites and drive away the introduces.
  • They have a life span of about 3-6 years.

How does Nemo survive in the wild?

Nemo, a species of clownfish, has a symbiotic relationship with the sea anemone, protects it from predators and gives them a hideout to avoid predators. Sea anemone provides food scrapes to them as their food.

Nemo fertilizes the sea anemone with its feces, providing the necessary nutrients for the sea anemone to grow and nourish. 

Nemo or clownfish have very peculiar survival body adaptability that helps them to survive in the wild. They are slow swimmers, there is no doubt, but they have great drifting ability, which allows them to make a sharp drift around, avoiding predator bites.  

The reason for this ability of the clownfish is their caudal fins that help them move around and gives them the ability to turn in different directions without being caught. 

If you are setting yourself up a little aquarium with Nemo as your pet, you better be mindful that they can’t control their movement if the current is strong. So, keep that in mind when setting up the aquarium for your Nemo. 

Another interesting fact about Nemo is that they can camouflage themselves to the same colour as the sea anemone to avoid their predators and rest without worrying about being captured.

What are the life stages of Nemo?

Nemo’s reproductive life starts with egg fertilization, as other fish do, and is natural and mutual to all other fish. Nemo or the clownfish reproductive cycle is remarkably interesting because they can change their sex. 

Newborn clownfish are male by birth, but they can change their sex depending on the need or when the dominant female dies out of their community. A dominant male will change their gender to female and will, mate with the other male and will reproduce to ensure the continuity of their species. 

Life stages

The life stages of the clownfish include the embryonic period, incubation period, larval stage, youth stage, and sub-adult period. 

  • After fertilization of the egg, the embryo stage proceeds, and a smooth chorion membrane develops.
  • Then the egg moves to incubation which takes place after sunset and is peaked during complete darkness. 
  • After the incubation period, larva develops; in this stage, total ossification of the axial skeleton happens. 
  • After the larval period completes, the youth stage comes, and in this stage, the vast majority of temporal organs are replaced with the definitive organs. This stage involves the development of the larval to the juvenile stage and deals with major body changes. It is the stage when fish starts to eat.
  • Next is the stage of rapid growth marked with aggression and territory marking and involves gametes maturation.
  • The adult period is measured with eth maturation of gametes that allows them to reproduce.
  • A stage comes when the egg production, spawning frequency, and growth rate decrease. The senesce comes 6 to 7 years after first spawning. 


In this blog, we answered the question What type of fish is Nemo? We also covered the characteristics of Nemo and the class to which it belongs. We also covered how Nemo survives in the wild and adapts to their environment, along with the reproductive and developmental stages of Nemo.
