Species Overview
The Super Blue Emperor Tetra (Inpaichthys kerri) is a selectively bred form of the Blue Emperor Tetra known for its especially intense blue to violet-blue coloration. Its metallic color can shift noticeably with aquarium lighting and the angle of the fish, while a darker lateral stripe provides contrast along the body.
These Tank-Bred tetras are small, active community fish that show their best behavior and appearance when maintained in a proper social group. Rather than purchasing one or two as individual display fish, keeping a group allows the Super Blue Emperor Tetra to interact naturally while creating considerably more movement and color throughout the aquarium.

The blue color is stunning, especially under LED lighting. I kept six fish together and they swim in tight groups, creating a lively scene. Easy to care for and very active.

These tetras are vibrant and show off their colors beautifully. I noticed the blue shifts depending on the light, which is a nice effect. They’re peaceful and don’t bother other fish.

Great color and active behavior. I kept them in a 55-gallon tank with plants and gentle flow. They seem to thrive in groups and are easy to maintain.

The tank-bred quality is noticeable. The blue hue is richer than standard Blue Emperor Tetras. I’ve had them for three months and they’re still lively and healthy.
