tetra breeding feeding and keeping

Tetra’s are among the most common and popular tropical fish. This is due to their small size, calm temperament, low cost, hardiness and strong colorations.

Tetras are very easy to care for and can be housed with almost any other non-agressive species. The small size and nature of Tetra fish often means they will school together in the aquarium. This is a desirable trait in freshwater species and can add a brilliant effect to any large aquarium.

There are countless species of tetra. The most common aquarium additions include Neon Tetra, Cardinal Tetra, Penguin Tetra, Harlequin Tetra, Rummynose Tetra, Glowlight Tetra, Ember Tetra & Glowlight Tetra. These species have excellent colorations, lively personalities and are less sensitive to water conditions than other fish. They have a maximum size of 2" and can live up to 10 years in captivity if properly cared for.

Purchasing Tetras

Tetra species are originally South American streams including the Amazon. This explains their need for softer water conditions and lower pH. Although tank bred varieties will tolerate elevated levels of pH or dH, lowering these will help them thrive.

A few species of tetra like the Congo Tetra tend to be more aggressive and are best kept in a species aquarium. Discuss stocking options with your local fish store and mention your concerns about compatibility before making any purchase decisions. An excellent, reasonably priced tetra to trial as your first tropical fish is the neon tetra. These are easily identifiable by their bright red and neon blue stripes. They are usually around $1 each and even less when purchased in a school.

Tetras are best purchased as a school of at least 3 to 4 of the same species. This will help make the fish more secure in the environment and less stressed.
