Penguin Tetra

The penguin tetra, Thayeria boehlkei, is a small and lively freshwater fish native to the waters of South America, particularly found in the Amazon River basin. Known for its distinctive coloration and active swimming behavior, the penguin tetra typically grows to about 2-2.5 inches in length. It features a translucent body adorned with a striking black stripe that runs horizontally along its side, reminiscent of a penguin’s coloration, hence its name. The fins are often tinged with shades of orange or yellow, adding to its visual appeal.
 
Penguin tetras are social fish that thrive in groups of six or more, displaying their natural schooling behavior in a community tank. They prefer well-planted aquariums with plenty of open swimming space, along with some hiding spots to mimic their natural habitat. Ideal water conditions for penguin tetras include temperatures of 72-82°F and a pH level ranging from 6.0 to 7.5.
 
As omnivores, penguin tetras enjoy a varied diet that includes high-quality flakes, pellets, and live or frozen foods such as brine shrimp and daphnia. Their peaceful nature and striking appearance make them an excellent choice for community aquariums, where they can coexist harmoniously with other small, non-aggressive species, bringing lively movement and color to the tank.
