What to know before you buy.
The Emperor Tetra is a regal fish with a unique trident-shaped tail fin in males and striking blue eyes. They are not a tight schooling fish but prefer to shoal, with males often displaying to each other. Their subtle purple and yellow sheen makes them a sophisticated addition to a peaceful community tank.
