Glass Tetra

The glass tetra, Moenkhausia sanctaefilomenae, is a captivating freshwater fish known for its unique and translucent appearance. Native to the rivers and streams of South America, particularly in the Paraguay and Paraná river basins, this small tetra typically grows to about 1.5-2 inches in length. Its most distinguishing feature is its almost transparent body, which allows observers to see the internal organs and bones, giving it an ethereal look. The glass tetra also has a hint of iridescence, especially under bright lighting, which enhances its beauty.
 
Glass tetras are social creatures that thrive in groups of six or more, exhibiting natural schooling behavior that makes them an engaging addition to community tanks. They prefer well-planted aquariums with open swimming areas and some hiding spots, mirroring their natural habitat. Ideal water conditions for glass tetras include temperatures of 72-82°F and a pH range of 6.0-7.5.
 
As omnivores, glass tetras enjoy a varied diet consisting of high-quality flakes, pellets, and live or frozen foods like brine shrimp and daphnia. Their peaceful demeanor and striking appearance make glass tetras a popular choice among aquarists, adding charm and movement to aquariums while being compatible with a wide range of other fish species.
