History, Origination & Distribution

The Black Phantom Tetra is a newly discovered freshwater species from the twentieth century. Hence, in order to reproduce their habitat in your tank, you must have a thorough grasp of it.

One will find this phantom tetra fish swimming through the sluggish tributaries and backwaters such as rivers, ponds, and lagoons.

Their lifestyle and habitat lean towards aquatic vegetation, so it is common for them to belong to the Neotropical and Paraguay vegetation.

Since they are endemic in South America’s inland water, their home resides in the upper Paraguay and Guapore river basins. 

How Big Does this Fish Get?

The average size of black phantom tetra is about 3.5 cm, but it can grow up to 5 cm.

Moreover, the size of the phantoms in the wild can be taller.

Their dimensions make them very comfortable integration for any community tank or aquarium.

Good to Know: The black phantom tetra gets its nickname ‘dwarf tetra’ because of its size.

Colour and Appearance

Black Phantom Tetra – Care Guide

Contrary to popular belief, their dark and easeful color is a heartthrob that adds immense class to the tank.

To differentiate the black phantom tetra from the other breeds, look for a black mark on either side of the fins, and it would be hard to miss.

The black phantom tetra has a tetragonal and rhomboid structure that construes their bodice. Moreover, their long-tailed fin and red or gray dorsal fins are defining characters.

While giving attention to detail, look for the black vertical line that separates their upper and lower bodice.

Maximum Life Expectancy

The longevity of the black phantom tetra is 3 to 5 years in captivity. Their lifespan can increase up to 1 year more by correct maintenance.

Adding a single tetra or a school of at least 6 + black phantom tetras is strongly suggested (with one male and more females). If you want to keep your fish alive for a considerable time, avoid brackish water.

Male or Female – How Do we Tell them Apart?

Some key characteristics assist in differentiating the gender of phantom fishes as they show a relatively higher sexual dimorphism.

  • Fin: Look out for the length. The male black phantom tetras tend to have longer fins than the female.
  • Dorsal Fin: The concentration of the color of the dorsal fin is a credible differentiating factor. The female phantom’s dorsal fin is blacker compared to the male.
  • Adipose fin: The adipose fin is behind the dorsal fin. The female fish adipose fin is more noticeable than that of the male.
  • Behavior: Surprisingly, one can conclude their gender even though their behavior. The male phantoms are more territorial as compared to the female black ghost tetras.

Black Phantom tetras aren’t a troublesome breed because their nature is harmonious and social.

Although, there are some factors that the fish parent must be sure to consider.

These fishes are prone to attacking the fins by exchanging blows. Be sure to notice their dorsal and anal fins, as it is how they express themselves.

They might get discreet and require a credible hiding place in the presence of a larger neighbor. Hence, they are usually found swimming in the mid-depth of the water.

Reproduction: How does it occur in the black phantom tetras?

Given below is an intricate guide on how the ghost tetra reproduces.

Mating and Breeding

The breeding difficulty in the black phantom tetra is hard. Hence, many fish keepers use conditioning to their power. Although, the phantoms can breed in captivity.

Tweaking the external environment and rendering a mating-friendly tank can spike their possibility to mate.

Keep the following tips in mind for a successful mating procedure:

  • Blood worms are used as a conditioning food. Hence, be sure to feed them with it once a day.
  • Make the tank more acidic. Decrease the Ph of the tank to 5-5.5
  • Lower temperature, higher breeding chances. Reduce the temperature by 4 degrees than the ideal one.

This must lead to a successful mating procedure.

Spawning

As spawning is induced, it is necessary to learn the procedure.

The black phantom tetras are oviparous and spawn in the open water. Given that they are an egg scattering species, the female releases more than 300 eggs.

Within 48 hours, the egg hatches.

After the spawning procedure is complete, separate the fry from the tank as the parent fishes tend to feed on it.

Ensure that you feed the fry a sufficient amount of infusoria. Their development speed is relatively high, and they are hardy, so the fry will be matured within five days.

Author Note: Separate the phantoms in pairs to maximize the breeding procedure.

Can They Fall Ill?

In a nutshell, the black phantom tetras can fall ill. Having a clear insight into the symptoms and diseases can mitigate the probability of it being fatal

  • Reduced mobility and activity.
  • White spots and coloration around their fins, mouth, and other body parts.
  • Malnourishment (The tetra appears to be more slender than usual)

The phantom black tetra can be prone to the following diseases –

  • Fungal infections are most common
  • Bacterial infections such as columnaris
  • SBD
  • Dropsy
  • Ick

The external environment plays a crucial role in their health. Sometimes when their living conditions aren’t optimal, they fall sick.

Keeping a suitable diet, temperature, and water current are vital.

Any filter that generates a minimal water movement is the correct choice, or else it can be hazardous for their health.

Peat filter is a credible suggestion. 

Pro Tip: Chlorine is a very hazardous chemical for any kind of fish. Hence, be sure to make use of anti-chlorine in each change. 

Water Parameters

The water parameters make or break the sustainability of a fish in the tank. Hence, for the black phantom tetra, keep the following water levels in mind- 

  • They prefer acidic-neutral water ranging from 6-7.5 PH. 
  • The tropical fish is comfortable and happy with a temperature between 22-28 degrees C. 
  • The phantoms have an endurance of hard water. Hence, the hardness of the water must range between 10-18 GH. 
  • The nitrate concentration mustn’t be more than 50 mg/l 
  • Change 20-30 percent of the water every month. 

Tankmates – Who Make a Good Fit?
