Care and Environment

Providing optimal care for Penguin tetras involves replicating their natural habitat and meeting their specific needs.

What is the minimum tank size for a Penguin tetra?

A minimum tank size of 60 liters is recommended to house a small group of Penguin tetras comfortably.

What are the ideal water parameters for Penguin tetras?

Maintain a water temperature between 22°C and 28°C, with a pH range of 5.5 to 7.5.

How should I set up the tank for Penguin tetras?

Incorporate live plants, driftwood, and rocks to provide hiding spots and mimic their natural environment. Ensure there is ample open swimming space, as Penguin tetras are active swimmers.

Regarding filtration and lighting, use an efficient filtration system to maintain water quality, and provide moderate lighting to support plant growth while allowing for shaded areas in the aquarium.

As omnivores, Penguin tetras accept a variety of foods. Offer high-quality flake or pellet foods supplemented with live or frozen options like bloodworms, brine shrimp, and daphnia to ensure a balanced diet.

Be aware that Penguin tetras can be susceptible to diseases such as Neon Tetra Disease. Quarantining new tank additions and maintaining high water quality are essential preventive measures.

Origin and Habitat

Penguin tetras are native to the upper Amazon River Basin in Peru and Brazil. They inhabit slow-moving rivers and tributaries characterized by slightly acidic to neutral waters, with temperatures ranging from 22°C to 28°C. These environments often feature sandy or muddy substrates, abundant leaf litter, and dense aquatic vegetation, providing ample hiding spots and feeding grounds.

Temperament and Compatibility

Penguin tetras are peaceful, schooling fish that thrive in groups of six or more. Their social nature makes them excellent candidates for community tanks.

Are Penguin tetras compatible with other fish species?

Yes, they coexist well with other peaceful species such as Neon tetras, Guppies, and Corydoras.

Can Penguin tetras be kept with aggressive fish?

It's advisable to avoid housing them with aggressive or fin-nipping species, as this can lead to stress and potential harm.

How can I create a harmonious tank community with Penguin tetras?

Ensure the tank is spacious enough to accommodate all inhabitants comfortably, provide plenty of hiding spots, and maintain stable water conditions to promote a peaceful environment.

Interesting Facts

Penguin tetras exhibit a unique swimming behavior, often tilting their bodies upwards, which has earned them the nickname "Hockey Stick Tetra."

How long do Penguin tetras typically live?

With proper care, they can live up to 5 years in captivity.

Are Penguin tetras easy to breed in home aquariums?

Yes, they are relatively easy to breed. They are egg scatterers, and providing a dimly lit aquarium with fine-leaved plants can encourage spawning. It's important to remove the parents after spawning to prevent them from eating the eggs.
