Dory, The Blue Tang Fish


Dory is a beloved character in the animated movie “Finding Nemo” and its sequel “Finding Dory”. She is portrayed as an absent-minded but kind-hearted fish who suffers from short-term memory loss. But many people wonder what kind of fish Dory actually is. In this article, we will explore the physical characteristics that define Dory’s species.

Physical Characteristics of Blue Tang Fish

Blue tang fish (Paracanthurus hepatus), commonly known as Pacific blue tangs, are found primarily in the tropical waters of the Indo-Pacific Ocean. They have flat, narrow bodies with vibrant blue coloration and yellow tail fins. These fish can grow up to 30 cm long, making them quite large compared to other reef fish.

The distinctive blue coloration of the blue tang covers most of their body, but they also feature black markings on their face, eyes, dorsal fin, and tail. One unique characteristic of these fish is their ability to rotate the eyes independently, allowing them to observe multiple objects at once.

You may notice that Dory has a darker-colored pattern around her eyes and mouth. This shading is common among juvenile blue tangs, but it fades away as they mature into adults.

In addition to their striking appearance, blue tangs have sharp spines along their backbone that help protect them from predators. While these spines may seem dangerous, they are only used for defense purposes and do not contain any venomous properties.

Native Habitat Of Blue Tang Fish

Geographical Location

The Blue Tang fish, also known as Dory, is a saltwater fish that is found in the Indo-Pacific region. They are primarily found along the reefs of Indonesia, Malaysia, Philippines, and surrounding areas. These regions offer ideal conditions for blue tangs to thrive.

Blue tangs prefer living in shallow, warm waters ranging from 24-30 degrees Celsius. Some of their preferred habitats include coral reefs, rocky outcrops, and seagrass beds. In these environments, they can find food, shelter, and protection from predators.

Water Conditions

In their natural habitat, Blue Tang fish require excellent water quality with high oxygen levels. The acidity levels should be between 8.1 and 8.4 pH because they need alkaline conditions to thrive. Water salinity should range from 32-35 parts per thousand (ppt) which closely approximates seawater levels.

To maintain optimal health, it’s essential to keep the water temperature stable and consistent. Any fluctuations may cause stress to the Blue Tang fish, making them more susceptible to diseases or infections.

It’s important to note that obtaining a Blue Tang fish as a pet requires extensive research and preparation before attempting to create similar water parameters suitable for its survival.

The Blue Tang fish, popularly known as Dory, is native to the warm waters of the Indo-Pacific region. These beautiful saltwater fish live comfortably among the coral reefs, rocky outcrops and seagrass beds of Indonesia, Malaysia, the Philippines, and surrounding areas. To maintain optimal health, it is essential to replicate their habitat’s water conditions as closely as possible.

Physical Characteristics Of Blue Tang Fish

Size and Shape

The blue tang fish is a popular marine species, widely known for its striking appearance. These fish typically have an oval-shaped body with a pointed snout, and they grow up to 12 inches in length.

Their small size makes them suitable for smaller aquariums, but it’s necessary to keep them in large groups as they are social creatures and exhibit better behavior when kept alongside their own kind.

Blue tang fish express sexual dimorphism, meaning males and females look different from each other. Males tend to be larger with more extended dorsal fins than their female counterpart.

Coloration and Patterns

The vibrant colors of the blue tang fish make them a favorite amongst aquarists and experts alike. They have a deep royal blue color that covers most of their body with black markings around the eyes and a yellow anal fin at the bottom part of their abdomen.

The juvenile counterparts of these fish usually possess bright yellow coloring throughout their bodies instead of blue until they reach adulthood. Their skin also carries smooth scales, which provide a sleek shine reflecting off of their stunning hues.

The blue tang fish boasts distinctive physical characteristics such as its unique shape and vibrant blue color, making it stand out from the rest in the ocean world. Keeping these curious critters in your home aquarium requires responsibility, love, and understanding.

Behavioral Patterns Of Blue Tang Fish

Feeding Habits

Blue tang fish, also known as the regal tang or surgeonfish, are herbivorous feeders in their natural habitat. They mainly consume marine algae from hard surfaces like rocks and coral reefs.

Their diet consists of a variety of green seaweed species such as Ulva (sea lettuce), Dictyota, and Halimeda. The blue tangs use their sharp teeth to graze on the algae, which can grow up to 9 inches long. They spend most of their day searching for food that keeps them energized throughout the day.

If these fish don’t get enough food, they become lethargic and inactive resulting in serious health problems. Therefore, it is crucial to provide them with an adequate amount of vegetables that have essential vitamins and minerals.

Social Behavior

Regal tangs live in the Pacific Ocean, Indian Ocean, and near Australia’s Great Barrier Reef. These highly social creatures love to move around in groups consisting of other blue tangs and different varieties of fish species. In fact, the nature of schooling among regal tangs was studied and reported by several scientists.

A study conducted at Lizard Island showed that young tangs in groups were faster reaches compared to the solitary ones. Moreover, the researchers discovered that fish learn and remember important information collectively – namely threats, breeding ground locations, and feeding sites. It is evident that having good relations with each other might help cope with stress-inducing situations better.

While observing these fish, one may notice unique behavioral patterns such as sudden swim bursts, slow swims with certain body language, inclined position, or darting out when sensing danger. Additionally, the males tend to be more protective of their home territories compared to female one’s.


The blue tang fish breed year-round, particularly during the warm summer months. They reach maturity at about 9-12 months old and, on average, grow to be 8 inches long.

A study shows that regal tangs have a special way of mating when breeding; females release their eggs in a specific meeting area, after which males fertilize them by releasing sperms. Younger male tangs are often referred to as “sneakers” because they tend to sneak into these meetings areas and fertilize some egg clumps before dominant male ones can get around to it.

Once the eggs are fertilized followed by hatching (5 days), the larvae still require feeding assistance from their parents for approximately two weeks until they’re big enough to swim independently. A baby blue tang can remain sticky due to its mucus coat that helps protect it from predator attacks while growing up.

Migratory Patterns

Blue tang fish don’t migrate during any part of their life cycle. In fact, most of them form stable groups within home territorial reefs throughout Austrailia’s wild waters, with aggregation sites extending across hundreds of kilometers. The extended range allows populations to benefit from diverse food availability and physical properties of habitats where their water temperatures may vary seasonally.

“Based on our findings studying reef fishes and sharks, we believe that marine reserves should represent as many different types of coral reef ecosystems as possible within manageable spatial scales,” said Michael Heithaus, an expert in shark ecology and conservation.

Blue tang fish play key ecological roles as central grazers in coral reef communities. Their feeding habits keep algae populations under control, promoting coral growth, and providing shelter for other fish. Furthermore, their social behavior and unique mating habits make them highly fascinating creatures to study by biologists.
