Species Summary

The Black Phantom Tetra, scientifically known as Hyphessobrycon megalopterus, is a popular freshwater fish species among aquarium enthusiasts. It is commonly referred to as the Black Phantom Tetra due to its striking appearance and dark coloration. The Black Phantom Tetra is also commonly known as the Black Tetra or the Black Widow Tetra.

Native to the Amazon River basin in South America, the Black Phantom Tetra is found in various countries including Brazil, Colombia, and Peru. It inhabits slow-moving rivers, streams, and flooded areas within the dense vegetation of the Amazon rainforest.

Appearance

The black phantom tetra is a small fish with a sleek and elongated body shape. It has a slightly compressed body, which means it is flattened from side to side. This body shape allows the fish to easily maneuver through the water and navigate through plants and other obstacles in its environment.

One of the most distinctive features of the black phantom tetra is its coloration. As the name suggests, this fish is predominantly black in color. However, it also has a shimmering silver or blue iridescence that gives it a beautiful and eye-catching appearance. This combination of black and silver/blue creates a striking contrast and adds to the overall allure of the fish.

FUN FACT

The black phantom tetra has two dorsal fins, one located towards the front of its body and the other towards the back. These fins are triangular in shape and are generally transparent, although they may have a slight black or dark gray coloration. Its anal fins are located on the underside of the fish near its tail. These fins also transparent with a black or dark gray hue.

The black phantom tetra gets its name from a unique eye-shaped marking located behind its gills. This marking is black in color and resembles an eye, complete with a circular shape and a dark center. It is believed that this marking serves as a defensive mechanism, confusing predators by making them think that the fish is facing in a different direction. This eye-shaped marking is a fascinating adaptation that adds to the mystique of the black phantom tetra.

Native Habitat and Distribution

Originating from South America, specifically Bolivia and West Brazil, Black Phantom tetras are accustomed to warm waters with dense vegetation. In the wild, they inhabit slow-moving rivers, streams, and flooded areas where they can find shelter among submerged roots or fallen leaves. Their natural habitat also includes areas with ample crustaceans and other small aquatic organisms on which they feed.

Size, Growth Rate, and Lifespan

Adult black phantom tetras typically reach a size of around 1.5 to 2 inches (3.8 to 5 centimeters) in length. It usually takes them about 6 to 8 months to reach full maturity. Black phantom tetras are considered to be relatively fast-growing fish. They can experience noticeable growth within a few weeks, especially when provided with a nutritious diet and optimal black phantom tetra tank conditions.
