How to feed the Emperor tetra?
Omnivorous: live prey will be the basis of its diet (daphnia or artemias for example), but all forms of food are accepted. Note that it likes small flies. By respecting this diet, the tetra’s color will be accentuated and this will encourage it to breed.

Behavior
What kind of behavior does the Emperor tetra have?
The Emperor Tetra is far from shy! Beware of aggression between males: make up your group with a ratio of 1 male to 3/4 females. Ideally, have 3 males so that the aggressiveness of the dominant does not always target the same rival. With this, you already have a nice group of 12 individuals, minimum! Do not worry, the agressions will not be serious if you have a good decor and a territory large enough.
Like all species of the genus, it is gregarious and must imperatively be kept with a shoal.

Who can live with the Emperor tetra?
Community aquarium accepted. However, avoid cohabitation with long-finned fish such as Scalars, Guppies, Fighters, under penalty of continual harassment, and they could damage the fins.
You can associate it with Danios, Rasboras or ground-fish like small Loricariidae. Dwarf cichlids like Apistogramma are also good companions. Also note that cohabitation with larger shrimp (Japonica type) is possible.
Finally, watch out for the predation of big fish and cohabitation with Corydoras that can intimidate.

Breeding
How to breed the Emperor tetra?
Breeding will be easier in groups (females may be slightly more numerous than males). Place the group in a 50 L (13 US Gallons or 11 Imperial Gallons) container with a protective grid and tufts of fine-leaved plants (java mousse). Temperature 24/26°C or 75/79°F and pH to 7 with moderate lighting. Females are not very prolific and success depends mainly on the choice of males. Before spawning, separate males and females for 15 days, then re-introduce the couple into an aquarium and stimulate breeding by feeding them live prey. As soon as you observe the presence of eggs, remove the parents. The incubation lasts 24 hours. Leave the eggs in the water where the parents were.
Fry food: Artemia nauplii.
