The Red Phantom Tetra, scientifically known as Hyphessobrycon sweglesi, is a small, peaceful freshwater fish native to the rivers of South America. Recognized for its vibrant red coloration and distinctive dorsal fin, this fish is a favorite among hobbyists for its stunning appearance and calm demeanor.
In the wild, Red Phantom Tetras inhabit slow-moving waters, such as streams and rivers, often in areas with dense plant growth. They thrive in slightly acidic to neutral pH levels and prefer warm water, conditions that can be replicated in a home aquarium.
Red Phantom Tetras are relatively easy to care for, making them suitable for both novice and experienced aquarists.
To create an optimal environment for Red Phantom Tetras, consider the following setup:
Red Phantom Tetras are known for their peaceful nature, making them ideal for community tanks. They pair well with other non-aggressive species such as:
However, avoid housing them with larger, aggressive fish that may see them as prey.
Red Phantom Tetras are omnivorous and thrive on a varied diet. Consider the following feeding options:
It’s essential to feed them a balanced diet to maintain their health and color.

The Red Phantom Tetra is an excellent choice for those looking to add color and tranquility to their aquarium. With proper care, they can live for several years and contribute to a harmonious aquatic community.
Use a tank of at least 60–75 cm (24–30 inches) in length to accommodate a group of Red Phantom Tetras.
Introduce the fish to the tank gradually to minimize stress and ensure a smooth transition.
Keep the water temperature between 22–28°C (72–82°F), pH between 5.7 and 7.0, and hardness between 4–12°dH.
Use subdued lighting to mimic their natural habitat and reduce stress.
Offer a variety of foods, including quality micro-flakes, small sinking granules, and occasional live or frozen foods like baby brine shrimp and daphnia.
Keep them with other small, peaceful fish that prefer similar water conditions to maintain harmony.
Maintain a temperature of 22–28°C (72–82°F), pH between 5.7 and 7.0, and water hardness of 4–12°dH for optimal health.
It's best to keep at least 8–10 Red Phantom Tetras together to encourage natural schooling behavior.
Red Phantom Tetras typically reach a maximum size of 4 cm (1.6 inches) in length.
With proper care, Red Phantom Tetras can live for 3–5 years.
Red Phantom Tetras are native to the upper and middle Orinoco River basin in Colombia and Venezuela, inhabiting slow, vegetated blackwater and clearwater creeks.
