Blue Phantom Pleco Overview

This is a fish species found in the Amazon River basin in South America. It is also known as L128.

It grows to a length of up to 7 inches. It can also be a bit territorial as it will not hesitate to attack other fish who come too close and make them feel threatened.

The Phantom Pleco is a popular aquarium fish because it has a cheerful temperament and is easy to care for. It can be kept in either tropical or temperate water conditions and should be fed small pieces of meat, vegetables, and fruit.

Its amicable disposition and ability to coexist peacefully with other fish make it a popular choice for community fish tanks.

Any significant factors do not currently threaten the Blue Phantom. Still, its population may be declining due to the expansion of the Amazon River basin into new areas and the loss of habitat due to deforestation.

If you are interested in keeping this fish as an aquarium pet, please be aware that it requires ample space for its activeness. If you are considering buying this fish, please research first to ensure it is a suitable pet.

Origin And Classification

The fish is from kingdom Animalia, phylum Chordata, subphylum Vertebrata, class Teleostei, order Siluriformes, and family Loricariidae. The genus of the fish is Hypostomus, and the species name is Hypostomus Plecostomus L.

It is believed to have been introduced to other parts of the world through the aquarium trade. It is not known to have established populations outside of its native range.

However, it is possible that individuals could escape from aquariums and establish populations in other parts of the world.

Habitat

The blue phantom is a natural freshwater fish that prefers to live in slow-moving waters, such as rivers, creeks, and lakes. They can also survive in acidic soft waters.

They are primarily found in Rio Orinoco in the downstream area of Puerto Ayacucho.

The blue phantom is a nocturnal fish, meaning that it is most active at night. During the day, these fish will hide in caves or among the roots of plants.

The fish species is a bottom-dweller, meaning that it spends most of its time exploring the depths of the water.

This fish is an omnivore and will eat small fish, invertebrates, and plant matter. The habitat of the blue phantom is essential for this fish because it helps to ensure that this species has access to food and shelter.

This fish is not tolerant of changes in its environment, so it is essential to keep its habitat consistent if you want to keep a specimen of this fish.

Water Parameters

According to the origin of the fish species, they are used to string water currents. They can, however, adapt easily to the mild movement of water.

This type of fish prefers warm waters with temperatures between 77 to 84 degrees. The pH level is acidic from 6.0 to 7.0.

You need to be extra careful with this as this fish species tend to die when the water becomes alkaline.

The fish is also highly sensitive to sudden changes in water quality or quantity. The water should be kept at the same level with adequate oxygen.

The water conditions are tested using the kit to keep track of the conditions required.

Appearance And Size

Their name comes from their body color: blue and beautifully stunned with white spots. They possess a typical shape of the plecos’ body.

Their dorsal fins are upright with a flat head and their mouth is modified to suck and dig. They also have abdominal solid and pectoral fins for digging deeper into the rocks.

The juveniles are 3 to 5 inches long. The mature ones are averagely 7 inches.

They have no scales, a unique feature that allows them to have plates for protection.

Care

The fish is easy to care for and is an excellent option for beginners interested in pet fish. You only need to provide plenty of fresh water with a moderate current and adjust the pH to 6.5-7.0.

You also need to remove uneaten food and debris from their tank daily or regularly.

However, you are required to use an aquarium heater in the winter if necessary to maintain a comfortable temperature range (around 75-80 degrees Fahrenheit).

Another thing to keep in mind is that blue phantom are omnivorous fish, so they require a diet mainly of meat and plant materials. They will also eat small aquatic invertebrates, but make sure you provide them with plenty of fresh food and vegetable matter too.

Substrate

It is a freshwater fish that requires a substrate of sand, gravel, or rocks. Plants are not necessary but can be used for decoration to make their environment natural in the aquarium.

This fish does best in an aquarium with plenty of hiding places. It may become aggressive when its territory is invaded by other plecos.

Sand and gravel are required because the fish feeds on small invertebrates that live in the sand and gravel. A filtration system is also necessary to keep the fish clean and healthy.

However, harsh gravels should be avoided so they don’t accidentally injure their fins.

Behaviour And Temperament

The fish species will be most active at night and reduces their activities during the day. They are popular in an aquarium because of their hardiness and beautiful pattern.

They prefer to stay hidden most of the time.

They are shy, but when they are comfortable in their habitat, they will come out of hiding. They are good community fish and can survive well with others.

But, they are a little sensitive to changes in the water quality, so it is advised to do frequent water changes to maintain the quality of the water.

They are also sensitive to medications, so caution is advised when treating them with any medication. The fish requires a temperature of 75 to 82 degrees Fahrenheit with a pH of 6.8 to 7.4 and a hardness of 2 to 12 dGH.

Breeding

The fish are livebearers in that they lay eggs. The female and males should be put in the same tank to facilitate this process.

Tanks that are 48 inches long are recommended because of the fish’s size. A small tank will only accommodate both males and females if they have enough spaces to hide and find their happy space in case of threats.

The young ones will be hatched in 24 hours, and the females should be fed frequently. The juveniles are many at the time of hatching, and a good number of them do not survive to maturity.

This may be because of elimination by nature or being fed on by other larger species.

The juveniles become adaptive at almost three weeks of age and start moving around the tank. This movement behaviour reduces their tendency to be fed on.

They grow rapidly during their first trimester, and they are transferred to their own aquarium. They then mature after one year and start spawning themselves.

Lifespan

The lifespan of the fish is typically around 10 years. However, some individuals have been known to live up to 15 years in captivity.

In the wild, their lifespan is shorter due to predation and other environmental factors. Plecos are generally sensitive and adaptable fish, so if their environment is maintained healthily, they should be able to live quite a long time.

Tank Requirements And Level

This is a bottom dweller small tropical fish that needs a lot of space to live comfortably. It needs at least 1 inch of water above its base and a tank size of at least 50 gallons minimum.

The pleco also requires hiding places and rocky surfaces to rest on.

Water changes every two weeks are also necessary for a blue phantom. Plecos are hardy and easy to care for, but they do require regular water changes to maintain good health.

Tank Mates And Compatibility

Compatibility in fish is when two different species of fish can live together in the same environment without harming each other. This can be due to the fish having similar dietary needs or because they can avoid each other’s territories.

Compatibility is essential for the health of both species, as it allows them to live in close quarters and share resources. It is also necessary for the environment, as it will enable different species to share resources and help to keep ecosystems healthy.
