Nemo is a very energetic young clownfish. He is very eager to go to school at the beginning of the movie, but lazy at the end. He is also quite friendly with anyone he meets.
His father’s over protectiveness leads to him being frustrated most of the time, which leads him into being captured by scuba divers. Adventuring and exploring are some of his likes. He can also be very brave, as shown when he was willing to risk his life to jam the filter after hearing about all his father had done to come and save him and when he willingly entered a net that captured a school of fish to lead them to freedom.
