Aquarists and pet fish lovers with aquariums are fond of the tiny, vividly colored freshwater fish known as tetras. Although many species have been introduced to other regions of the globe, they are indigenous to South America.
Here are a few facts about them:
- Tetras come in more than 700 species, but some of the most frequently maintained in aquariums are the neon, cardinal, black skirt, and serpae tetras.
- Tetras are renowned for their vivid colors and calm personalities despite usually being small fish that only reach lengths of a few inches.
- Tetras consume various foods in the wild, such as small insects, crustaceans, and plant matter. They can be given a range of commercial fish meals in captivity, such as flakes, pellets, and freeze-dried or frozen foods.
How to keep them
Tetras should be maintained in groups of six or more because they are social fish. They can be maintained in communal aquariums with small fish and invertebrates because they are typically calm.
Tetra species can vary in their nippy or fin-nipping tendencies, so it’s crucial to provide plenty of hiding spaces and swimming areas and carefully select tankmates. For example, Ember Tetras can live with Betta fish without problems since they thrive in the same conditions.
Tetras are hardy fish that can live in various water conditions, but keeping the water in their aquarium in excellent condition is crucial.
- They favor temperatures between 72 and 82 °F and a pH between 6.0 and 7.5.
Tetras are an excellent asset to any community aquarium because of their calm disposition, vibrant colors, and simplicity of maintenance.
