The Glolite Tetra, also known as ‘Glowlight Tetras’, have an iridescent silver body with an orange or red line running centrally from their nose to their tail.
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. The term Tetra is actually not a taxonomic grouping, as many unrelated fishes from differing families have been commonly called Tetras.
Tetras are the second most commonly kept fish in community tank setups, after livebearers (see our Livebearer Care Sheet for more information on these fish) . They are popular because of their vibrant colours, manageable size, mild behaviour and schooling habits.
Tetras range from 2 – 12cm depending on species. Longevity ranges from around 1 year for some small species to several years
