Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
These tetras are peaceful and active swimmers that do well in a community aquarium setting. They are shoaling fish, so it is recommended to keep them in groups of at least six individuals to help them feel secure and exhibit their natural schooling behaviour. Costae Tetras are generally non-aggressive and make excellent tank mates for other peaceful fish species.
Tank planning
Maintaining stable water parameters is crucial for the health of Costae Tetras. They prefer slightly acidic to neutral water with a temperature range of 22-26°C. Provide ample hiding places among plants and driftwood to create a natural environment for them to explore. Regular water changes and a well-maintained filtration system will help keep the aquarium clean and ensure the well-being of the fish.
