Black Phantom Tetra Species Profile and Identification

The Black Phantom Tetra, also known as Hyphessobrycon megalopterus, is a small, attractively colored fish native to the freshwaters of South America. With a uniquely shaped physique, it easily stands out in your aquarium.

  • Size: An adult Black Phantom Tetra measures from 1.4 to 1.8 inches (3.6 – 4.6 cm) upon attaining full maturity.
  • Color: Their bodies primarily showcase a muted silver-grey shade, convincingly accentuated by iridescent black patches.
  • Lifespan: If treated diligently with optimal care, these adorable creatures dwell for 4 to 6 years.

Recognizing a Black Phantom Tetra is simple. Males flaunt deep black coloration on their dorsal and anal fins, while females exhibit an alluring reddish hue to their anal fins. Only the males possess an enlarged dorsal fin. This fin becomes vertically erect during clashes or slight confrontations, crafting a majestic display.

Visual identification, albeit elementary, isn’t foolproof. Therefore, familiarization with their distinctive traits, including their semi-aggressive nature, comes in handy. Interestingly, the Black Phantom Tetra is often mistaken for its peer, the Red Phantom Tetra. Still, discerning hobbyists can spot the differences, most notably the color disparity on the dorsal and anal fins.

To ensure your fish tank is indeed a home to Black Phantom Tetras, follow this simple identification rule: ‘silver-grey body with black patches and differing dorsal and anal fin colors between males and females’. Always note, proper identification is a significant step towards successful fishkeeping.

Characteristic Description
Size 1.4 – 1.8 inches (3.6 – 4.6 cm)

Black Phantom Tetra Diet and Feeding

Understanding the dietary needs of your Black Phantom Tetra is crucial. These fish are omnivores.

In the wild, their diet consists of:

  • Small insects,
  • Crustaceans,
  • Plant matter.

As owners, your goal is to mimic this diet in your home aquarium.

Start by providing high-quality flake food. It should form the core of their diet. Ensure it’s rich in both:

  • Proteins,
  • Plant matter.

Occasionally, introduce live or frozen foods. You can use:

  • Daphnia,
  • Brine shrimp,
  • Bloodworms.

These additions provide key nutrients and mimic hunting rituals. It breaks the monotonous routine of flake food.

Remember to feed them sparingly. Overfeeding can lead to:

  • Health problems,
  • Poor water quality.

Follow the “5-minute feed rule.” Anything they can’t consume in 5 minutes is excessive. It adjusts portion sizes to their appetites.

Create a feeding schedule. Consistency is important. Feed them once or twice a day. It caters to their natural feeding patterns.

Black Phantom Tetra Care Schedule

Following a consistent Black Phantom Tetra care schedule is the key to having healthy, vibrant aquarium pets. Here’s a simple, direct guide to maintaining a routine that caters to their needs.

  • Daily: Feed your Black Phantoms with a balanced diet, typically twice a day. Small, frequent meals are advisable, as large feedings can pollute the tank. Monitor their behavior for any signs of health issues.
  • Weekly: Use a testing kit to check water parameters each week. This includes temperature, pH, and general hardness. These should ideally fall within 22°C-27°C/71.6°F-80.6°F, 6.0-7.5, and 100ppm respectively. Adjust as necessary.
  • Biweekly: Change about 20% of the tank water every other week. This helps keep nitrate levels down and ensure a fresh environment. Clean the glass with a proper aquarium-safe scrubber.
  • Monthly: Inspect the filtration system for any required maintenance. It should work properly to prevent ammonia spikes. Don’t forget to trim live plants, get rid of dead or dying ones, and check the substrate for vacuuming.
  • Annually: Replace light bulbs once a year, as their output decreases over time.

Accurate adherence to this care schedule is an integral part of Black Phantom Tetra keepership. Remember – the quality of care you provide directly affects your tetra’s health and lifespan, which can range between 4-6 years.

In essence, care for Black Phantom Tetras goes beyond feeding and water change. It also includes observing their behavior, maintaining their habitat, and regular checks for potential health problems.

Black Phantom Tetra Health Problems

Despite Black Phantom Tetras being considered hardy and resilient, they are not entirely immune to health issues. Here are few common problems you should be aware of:

  • Ich: Also known as white spot disease, Ich is a common health concern in aquarium fish. Indications include white spots on your tetra’s body and erratic swimming behaviors. The best remedy is a specific ‘Ich treatment’ available at pet stores.
  • Fungal infections: These are common in environments with poor water quality. Symptoms include fluffy white patches on the body or fins. Regular water changes and addition of anti-fungal medicines can help combat these problems.
  • Fin rot: A consequence of bacterial infection, fin rot causes the fins to discolor and fray. It’s vital to incorporate antibiotic treatments and maintain water cleanliness to treat this issue.
  • Bloated stomach or swim bladder disease: The symptom is exactly as the name suggests – the fish’s belly becomes bloated, and the fish may float upside-down. A balanced diet, reducing feeding, and medication can alleviate this.

Below is a table that shows these diseases, their symptoms, and possible treatments.

Disease Symptoms Treatment
Ich White spots on body, erratic swimming Ich treatment
Fungal Infections Fluffy white patches on body or fins Anti-fungal medicines, water changes
Fin rot Discoloration and fraying of fins Antibiotic treatments, maintain water cleanliness
Swim Bladder Disease Bloated stomach, fish swims upside-down Balanced diet, reduce feeding, medication

Remember, the key to ensuring your Black Phantom Tetras’ health is prevention rather than cure. Regular water changesfeed monitoring and keeping an eye out for odd behaviors will go a long way in maintaining their health.

Black Phantom Tetra Tank Mates

When it comes to choosing tank mates for your Black Phantom Tetras, it’s crucial to make the correct selection. Follow these guidelines:

  • Firstly, Black Phantom Tetras are peaceful fish, so avoid pairing them with aggressive species. This could subject them to undue stress or even injury.
  • Strive for a harmonious tank environment. Medium-sized freshwater fish make excellent companions. Species such as Neon Tetras, Swordtails, or Guppies are good choices.
  • They also fare well with other Black Phantom Tetras. A small school of 5-6 fish can create a stunning visual effect and can promote comfort and social interaction within the species.
  • Consider similar water condition requirements. Tank mates should be able to thrive in the same conditions — pH between 6.0 to 7.5, hardness levels between 8 to 18dGH, and temperature range of 22°C – 27°C (or 71.6°F – 80.6°F).
  • Consider adding some bottom dwellers too. Cory Catfish and Dwarf Gouramis make great tank mates as they occupy different areas of the tank and usually don’t cross paths.

Keep these tips in mind, and take pleasure in the serene and lively aquarium environment you’ll create.

Black Phantom Tetra Breeding

When it comes to breeding Black Phantom Tetras, it’s best to have a separate tank. This should be a smaller, 10-gallons or approximately 38-liters tank, dimly lit with some hiding spots for the female when she needs respite.

Here are some breeding tips:

  • Selecting Breeding Pairs: Do this based on bright coloration and vigor.
  • Tank Preparation: Soft, slightly acidic water (pH 6.0—7.5) and mid-70s degrees Fahrenheit (22°C – 27°C) aims to mimic their natural breeding ground.
  • Feeding: Feed them live or frozen food to prepare for spawning.

After a successful spawning, females will scatter around 300 to 500 clear to pale yellow eggs. Once eggs are laid, remove the parents to reduce risk of them eating the eggs or fry.

The eggs will hatch within a day. Initially, feed them infusoria-size foods. When they mature, you can gradually introduce brine shrimp and micro-worms.

Success in breeding can be challenging due to their egg-scattering nature and parental tendencies. Remain patient during this process. Equipping yourself with the right knowledge, you’re off to a good start in Black Phantom Tetra breeding.


Caring for Black Phantom Tetras, despite their specific requirements, can be greatly rewarding. With their unique coloration and peaceful nature, they make a fantastic addition to any home aquarium.
