The Emperor Tetras are stunning with their vibrant colors and shiny scales. I kept them in a 10-gallon community tank with neon tetras and they get along well. They stay calm and add a lot of visual appeal to the tank.

They are easy to care for and look beautiful under regular aquarium lighting. I noticed their black stipe stands out well against the background. Just make sure to keep them with calm fish and avoid strong currents.

I bought a group of five and they’ve been thriving for three months. They swim in schools and are very active without being aggressive. The colors are vivid and the fish seem healthy and happy.
