They are ‘great socialisers’ and get comfortable in large groups, but with suitable tank-mates.

Serpae and Buenos Aires are the only tetras who show superficial aggression to dominate other fish in the tank.

A group of at least six tetra fish is recommended.They don’t need special equipment around them to keep them happy.

All they need is balanced nutrition and clean sanitation like other fish.

Quarantine the new members for at least two weeks before introducing them to the main tank to avoid parasitic and other diseases.
