This graceful looking tetra, are best kept in planted tanks with other peaceful species. Males are easily identified by their blue eyes and longer fins. 


This is a very popular, graceful looking tetra, native to Colombia. Mature males are easily determined by their blue eyes and longer fins. Best kept in a planted aquarium with other peaceful species, it is not unusual to have self-sustaining populations in heavily planted aquaria. Maximum size is about 5cm.

Tetras are considered easy to keep in a community aquarium of at least 20L, with a pH of 5.07.0 and KH of 1.02.0. However, they will not tolerate dramatic changes to their environment. The Tetra can live 10 years or more with the proper conditions. They tend to be timid and, because of their small size, should not be kept with large or aggressive fish who may bully or simply eat them.

Fish that mix well in an aquarium are other types of tetras, and other community fish that live well in an ideal Tetra water condition. Mid-level feeders, they are best kept in schools of five to eight or more, for the "shoaling" effect when they move around the tank. They shoal naturally in the wild and are thus happier, more brightly coloured, and more active when kept as a shoal as opposed to singly.

Tetras are best kept in a densely planted tank with subdued light and an ideal temperature of 2024?C to resemble their native Amazon environment. Tetras are omnivores and will accept most flake foods, but should also have some small foods such as brine shrimp, daphnia, freeze-dried bloodworms, tubifex, and micro pellet food to supplement their diet.

Great fish! Stunning and fun to watch!
Ordered 5 of these and got 2 boys and 3 girls. No stress from the travel. Fit right in with my other fish and have bred a few times.

Emporer Tetra
Fish arrived really healthy and happy as I have come to expect from Live fish. Unfortunately these fish were really quite small and the size did not reflect the price in this instance. Hopefully wont get picked off by my angels and will start to grow soon

Very pretty though a tad aggressive
I ordered 12, one died shortly after being put into quarantine and another was euthanised since it looked on its way out. I seemed to receive mostly makes which is great from a display perspective although they are not peaceful as its literature says including Baensch. They seem to be quite aggressive though I am putting that down to a smaller space than they will eventually be in and boys being boys. I definitely recommend a densely planted tank for these guys to hide in. Beautiful fish though and some were closer to 5/6cm.
