Watch these Penguin Tetras with their horizontal black stripe in schools swim through your heavily planted aquariums. They also have a unique swimming style that will keep you entertained.

 

A Penguins diet in the wild mainly consists of crustaceans, insects, and larvae. Try live foods of brine shrimp and bloodworms. For a rounded diet, include nutrient-rich flake and pellet foods. Penguins are schooling fish and will need to be kept in a group of at least half a dozen. As calm schooling fish, keep them with other like-minded small fishes. Penguins will not do well with larger, aggressive fish with long flowing fins, like angelfish or guppies. Bottom-dwelling fish of a similar size would be suitable tankmates.

 

Keeping Penguins is easier when compared to other Tetras. They are not picky about their water conditions, when their waters are consistent. So long as water changes are regular and water tests are carried out, Penguins should be happy. They will spend most of their time in the mid to top levels of your tank, so, will be less affected by the type of substrate in your aquarium. But sand or small pebbles will suit their wild environments. Penguins will enjoy the dense vegetation, tree roots, and driftwood; these help them feel safe from brighter lights and predators. Skirt your vegetation closer to the outer areas of the aquarium, so Penguins have room to swim freely.

 

There are no distinguished physical differences between males and females, except females will have rounder bellies that become more noticeable when they are ready to spawn. Males may appear more brightly coloured. When getting ready to breed, slightly softer, acidic waters will prompt their breeding season. Create these waters in the separate breeding tank. Plant vegetation or use spawning mops so eggs have something they can settle in. Penguin adults will have to be removed from the tank to avoid eating their fry.
