Beautiful Blue Fish With Yellow Eyes

Fish can refer to any vertebrate from numerous evolutionary lineages. Instead of describing a taxonomic group, it represents a life form. A few fish and other vertebrates share several characteristics in the phylum Chordata, where they both belong. These characteristics include a tail, a notochord, or bony support rod; dorsal hollow nerve cords; and gill slits at some stage in the life cycle—any of the approximately 34,000 freshwater and saltwater fish species that exist worldwide. The diversity and abundance of living species span from the earliest jawless lampreys and hagfishes to the cartilaginous sharks, skates, and rays. Most fish species have cold blood, but the opah contains warm-blood. In this blog, we’ll discuss blue parrotfish.

A few words about parrotfish

The dentition of parrotfish, which is different from that of other fish, including other labrids, gives them their name. Their teeth are organized in a closely packed mosaic on the outside of their jaw bones, resulting in a parrot-like beak that they use to scrape algae from coral and other stony surfaces, aiding in bioerosion. Within the family, maximum sizes vary, with most species growing to a length of 30 to 50 cm. Only a few species, like the green hump-headed parrotfish, can grow longer than 1 m. The blue-lipped parrotfish, which can grow to a maximum size of 13 cm, is the smallest species. The parrotfish is one of the most beautiful species, with many sub-breeds. A list of their breeds is below. 

Blue parrotfish Sub-Breeding List: 

  1. Rainbow parrotfish
  2. King Kong parrotfish
  3. Polar Blue parrotfish
  4. Blue tiger parrotfish
  5. Ember parrotfish
  6. Jamaican parrotfish
  7. White parrotfish
  8. Purple parrotfish
  9. Yellow parrotfish

Other than the species mentioned earlier, there are a lot of different breeds of this specific fish. Blue parrotfish are fish that do not have any threat of disappearing from the waters.

1. Blue parrotfish

The western Atlantic Ocean and the Caribbean Sea are home to the Blue Parrotfish, scientifically known as Scarus Coeruleus, a member of the parrotfish family. This ocean-dwelling fish prefers tropical and subtropical seas. One of the almost 60 parrotfish species in reef waters today is the blue parrotfish. They are the second-largest species of parrotfish in the Caribbean and are common in the southern part of the Gulf of Mexico. A parrotfish famous as the midnight parrotfish lives mostly on coral reefs in the Caribbean, Bahamas, and Florida and is known as the Florida parrotfish.

They have an age-related fading yellow patch on their heads and are evenly blue. With a maximum size of 1.2 meters, or 3 feet and 11 inches, they range in size from 30 to 75 centimeters or 12 to 30 inches. They have a large “beak” like other parrotfish, which they utilize to scrape algae and other small creatures from rocks. Their pharyngeal teeth convert the stones they swallow into the sand. No other species’ adults are a consistent shade of blue. They weigh about 9.1 kilos each.

Do blue parrotfish face endangerment?

According to the International Union for Conservation of Nature, the Blue Parrotfish is classified as having a low Concern for endangered species and conservation. Although it is uncertain how many blue parrotfish there are, the species appears to be constantly expanding. The blue parrotfish will probably be reclassified as Critically Endangered in the next ten years, even though the species is now not thought to be in danger of extinction. Due to coral reef bleaching and human degradation, the blue parrotfish is at risk of becoming increasingly endangered.

The loss of healthy ocean coral will make it challenging for the blue parrotfish to adapt because this species relies on the reefs for food and refuge. Concerns about too much fishing of the species and overall harm brought on by extensive commercial fishing are also present. In some Caribbean nations, the blue parrotfish is consumed, and the scales are used to adorn goods sold by merchants. The brilliant blue color of the blue parrotfish scales makes them desirable for jewelry making, basket lining, and other household craft projects. Threats to the blue parrotfish include those caused by climate change and ocean pollution.

Diet and Behavior

Most blue parrotfish spend most of their time in search of food, which consists of dead coral covered in algae. Consuming algae from coral reefs helps to conserve the coral by reducing the number of algae that could smother it. They break up the coral to access the algae using their second dental set after grinding off chunks of coral with their first set of teeth.

Sand is deposited in these locations, made up of undigested coral fragments. It is crucial for the ecosystem because it forms the Caribbean’s sand beaches, but it’s also essential for blue parrotfish because it regulates the size of their teeth.

As this specific fish is a daytime creature, the blue parrotfish looks for cover at night. They accomplish this by secreting mucus that covers their aroma, tastes unpleasant, and makes them more challenging to locate. Each end of the mucus has a hole that lets the water pour over the fish when it sleeps. To ward off potential threats, males can also change their hues. With a male leader and all-female followers, they travel in sizable groups of forty people. The male is incredibly hostile, aggressively pursuing intruders up to 20 feet beyond the group. One of the females will experience a physical transition and turn into an aggressive, vividly colored male blue parrotfish if the male dies.


Although mating season lasts all year, it peaks from June to August. Both sexes mature sexually between the ages of two and four. As oviparous beings, females lay eggs that hatch in the water. They concentrate on massive reproductive groups at this time, and the males and females form couples. The female delivers the fertilized eggs into the aquatic environment after mating. After 25 hours, the eggs hatch on the seafloor. These larvae start feeding three days after they hatch. They prefer to live alone since birth. Young animals consume tiny plants and animals while feeding on turtle grass beds.

How to take care of blue parrotfish?

Blue parrotfish prefer water between 75 and 78 degrees Fahrenheit because they are native to warmer climates and need this range to maintain a healthy body temperature. Cooler water temperatures may result in blue parrotfish losing some of their color brilliance and possibly weakening their immune systems, putting them at an increased risk of catching infections and lethal diseases. In a tank with water that has an alkalinity range of 8.1 to 8.4, the Blue Parrotfish will survive. The aquarium tank will require routine water changes and tests to maintain good water quality and fish health when caring for reef species like the blue parrotfish. The blue parrotfish, a saltwater fish, will require a tank with a water salinity between 1.020 and 1.025.

Life span

Blue parrotfish can live up to twenty years comfortably in their natural environment. Still, even with reasonable care, they are more likely to live significantly shorter lives when in aquariums. While certain varieties of parrotfish make excellent aquarium inhabitants, it is not usually lead a happy or healthy life in captivity.


Are blue parrotfish good to eat?

Parrotfish are delicious to eat practically any way they are prepared, whether raw, fried, grilled, baked, or included in a curry.

For the people who pet or want to keep this specific fish breed, an aquarium fish that is mature and in good health can live anywhere from three days to a whole week without eating. Even some fish can survive for longer than two weeks without food. A fish’s body weight and fat reserves allow it to occasionally skip a few meals, whether in the wild or an aquarium.


It belongs to the most beautiful species of fish and has a lot of breeds. They are not so big. Due to their diet differing from that of other fish because they eat algae, putting them in the aquarium is difficult. Also, it needs a lot of care in many different aspects; one common element is maintaining the temperature. Purchasing a blue parrotfish falls into the high price range and can go up to $300. Since these are not very common aquarium fish and are not frequently caught for retail sale, it isn’t easy to locate them in stock at most aquatic businesses. Human-caused coral reef death or bleaching affects them. Furthermore, several nations frequently contract it, which consumes them even though it might result in fatal fish poisoning.
