Week 10: Emperor Tetra

This week’s Fish of the Week is the striking Emperor Tetra.

Originating from the San Juan and Atrato river basins in Colombia, this uniquely shaped Tetra can grow to around 4cm in length and can be easily identified by its forked tail and deep black stripe which runs down the entire length of its body.

This lively yet peaceful Tetra is compatible with most community fish and is best kept in shoals of 6 or more. Emperor Tetras are omnivorous and will accept most live, Frozen and flake foods.

The minimum recommended tank size for the Emperor Tetras is 60 litres. The aquarium water should ideally be kept with a temperature of between 22°C and 27°C with a pH of around 5 to 7.5.
