Latin Name: Paracheirodon innesi
Other Names: Neon Fish
How hard are they to keep? Neon Tetras are generally easy to keep, making them suitable for beginner aquarists. They are hardy and adaptable to a wide range of water conditions.
What is their maximum size? Neon Tetras typically reach a maximum size of around 1.5 inches (3.8 cm).
Where are they from? Neon Tetras are native to the blackwater streams and tributaries of South America, specifically the regions of Brazil, Colombia, and Peru.
How many can I keep? Neon Tetras are shoaling fish and should ideally be kept in groups of at least six individuals. However, larger groups are even better for their well-being and to showcase their beautiful schooling behaviour.
How compatible are they with other fish? Neon Tetras are generally peaceful and get along well with other peaceful fish species. They should not be kept with aggressive or fin-nipping fish as their long, delicate fins can make them targets. Suitable tank mates include other small community fish like guppies, platies, and rasboras.
What are the ideal water conditions? Neon Tetras prefer slightly acidic to neutral water with a pH ranging from 6.0 to 7.5 and a temperature range of 72°F to 80°F (22°C to 27°C). Soft and well-filtered water is preferred, and they appreciate the presence of live plants and plenty of hiding spots. The Neon Tetras that are for sale have been climatized to our local water conditions.
How do you tell the difference between male and female? It can be quite challenging to visually differentiate between male and female Neon Tetras. However, there are some subtle clues that can help. Males tend to have a more vibrant coloration and a straighter (or slightly bent) blue stripe running along their sides compared to the females. Females, on the other hand, are usually larger and have a slightly rounder belly when they are full of eggs.
Fun Fact: The vibrant neon colours that give Neon Tetras their name are actually a result of iridophores, specialized cells that contain reflective pigment. These cells give the fish its stunning fluorescent appearance and make them a popular choice for aquarium enthusiasts.
