The fish, up close
The Blue Emperor Tetra, scientifically known as Inpaichthys kerri, is a stunning freshwater fish species popular among aquarists for its vibrant blue colouration and peaceful nature. This tetra species boasts iridescent sapphire-blue bodies with a silver sheen that shimmers under the aquarium lights. Their fins are typically transparent with a hint of blue at the edges, adding to their overall elegance. Blue Emperor Tetras are schooling fish, so they thrive best in groups of six or more, showcasing their best colours and behaviours when kept in a well-planted tank with subdued lighting.

Plan your setupBehaviour
Blue Emperor Tetras are peaceful and social fish that do well in community aquariums with other non-aggressive species. They are active swimmers and enjoy exploring their environment, especially when provided with ample hiding spots among plants and driftwood. These tetras are known for their schooling behaviour, so keeping them in groups is crucial for their well-being.
Tank planning
Maintaining stable water parameters is key to the health of Blue Emperor Tetras. They prefer slightly acidic to neutral water with a temperature range of 24-27°C. Regular water changes and a well-maintained filtration system are essential to ensure optimal water quality. Provide a planted tank with open swimming areas and hiding spots to mimic their natural habitat.
