Appearance:

• Black and White Coloration: The Penguin Tetra is characterized by its striking black and white coloration, resembling the distinctive markings of a penguin. The upper body is predominantly black, while the lower body is white, creating an eye-catching contrast.

Water Conditions:

• Temperature: Maintain the water temperature between 24°C and 28°C (75°F-82°F) to provide optimal conditions for the Penguin Tetra.
• pH Level: Aim for a slightly acidic to neutral pH range of 6.0 to 7.5 to replicate their natural habitat.
• Water Hardness: These tetras prefer soft to moderately hard water, with a general range of 2 to 12 dH.
• Filtration: Ensure efficient filtration and regular water changes to maintain excellent water quality for the Penguin Tetra.

Tank Setup:

• Tank Size: Provide a spacious aquarium with a minimum capacity of 10 gallons to accommodate a small school of Penguin Tetras comfortably.
• Plants and Decorations: Incorporate dense planting, including floating plants, to provide ample hiding spots and create a natural environment. Use dark substrates and add driftwood or rocks to mimic their natural habitat.

Tank Mates:

• Peaceful Community Fish: The Penguin Tetra is a peaceful species that can be kept with other small, non-aggressive fish species that share similar water parameter requirements.
• Schooling Behavior: These tetras exhibit strong schooling behavior, so it is recommended to keep them in groups of at least five individuals. The presence of a school will help them feel secure and encourage natural behavior.
