Tetras are the most common type of fish found in South America after catfish. Their name is commonly used for a large group of fish characterised by the presence of a small adipose fin between their dorsal and caudal fin. They are popular because of their vibrant colours, manageable size, mild behaviour and schooling habits. Many species tend to have a silver coloured background to their body over which splashes of iridescent colours occur. The fins of many species also contain various colours and patterns.

Max Size:4cm


Many Tetras are omnivorous and will readily take most types of aquarium foods used in the hobby. Due to the small size of many species, ensure that food particles are not too large for their small mouths. Small pellets and flakes are best, as well as frozen tropical mixes and brine shrimp.


Tetras are best kept in large schools and different species can generally be kept together with few problems. Tetras will also mix readily with a range of species and are generally an ideal community fish. Beware of size differences as bigger fish may eat them and become aggressive. Best kept in schools of 6 or more.
