Tetras

Tetra Fish

Most species will adapt to a range of water conditions so long as the water is clean and well aerated. Extremely high pH (e.g. over 7.6, or 8 for hardy species) and very hard water should be avoided.

Most tetras will fade in color if they are stressed or uncomfortable with their surroundings. (But note that many lose all their color at night, which is not a cause for alarm).

They are schooling fish and will not be happy unless kept in a group of at least four of their own species.

Large fish such as Gouramis, Angelfish and Silver dollars should be avoided: even quite passive fish will eat other fish if they can fit them in their mouths!

Larger tetra species such as buenos aires tetras, congo tetras, serpaes and others can be mixed with quite large tank mates.

Breeding Tetras Tetras are egg scatterers that do not tend their eggs or fry and so a separate spawning/fry tank is needed. Spawning occurs usually between pairs, although some species spawn in schools.
