Penguin Tetra

The Penguin Tetra is a popular freshwater species among hobbyists due to its striking coloration and active nature. They are relatively small, growing to an average size of 2-2.5 inches (5-6.5 cm). They have a silver body with black and white markings resembling a penguin, hence the name Penguin Tetra.

In the wild, Penguin Tetras are omnivorous and feed on small insects, crustaceans, and plant matter. In captivity, they will readily accept a variety of foods, including flakes, pellets, frozen or live foods, such as bloodworms, brine shrimp, and daphnia. It is important to provide a varied diet to ensure their nutritional needs are met.

It can be difficult to determine the sex of Penguin Tetras, but males may be more colorful and have a slightly larger dorsal fin than females. Females may also appear rounder when viewed from above.

Penguin Tetras are relatively easy to breed in captivity. A separate breeding tank with soft, acidic water and fine-leaved plants, such as Java moss or spawning mops, should be set up. The males will establish territories and court females by performing displays and flaring their fins. After spawning, the adults should be removed, as they may eat the eggs. The eggs will hatch in 24-36 hours, and the fry can be fed infusoria or liquid fry food until they are large enough to eat newly hatched brine shrimp.

Penguin Tetras are generally hardy and not prone to specific diseases, but like all fish, they may be susceptible to bacterial or fungal infections if water quality is poor. It is important to maintain good water quality and a clean environment to prevent disease.

The Penguin Tetra is native to the Amazon basin in South America, specifically the rivers and tributaries of Brazil, Colombia, and Peru.

Penguin Tetras are generally peaceful and suitable for community aquariums, but they may nip fins of long-finned species. It is best to keep them in groups of at least six individuals to reduce stress and aggression.

Penguin Tetras should be acclimated slowly to their new environment to prevent shock. The bag should be floated in the aquarium for 10-15 minutes to equalize the temperature. Then, a small amount of aquarium water should be added to the bag every 5-10 minutes until the water volume doubles. The fish can then be gently netted and released into the aquarium.
